Flare Gas to Power refers to converting flare gas into electricity. Flare gas is excess gas generated by production processes that, in some industries, may be sent to a flare stack for appropriate disposal. However, when the gas can be recovered and put to productive use, a Gas-to-Power system can be designed to convert the energy contained in the gas into electrical power.

In the agricultural and industrial sectors, a common example is Biogas, which is produced through the decomposition of organic matter—such as animal manure, wastewater, or other organic feedstocks—under anaerobic conditions.

How Is Gas Converted into Electricity?

Generating electricity from gas involves more than simply connecting a gas supply to a generator. The entire system must be designed to suit both the properties of the gas and the electrical demand at the site.

The process generally begins with collecting gas from its source. The gas then enters a treatment system that controls moisture, contaminants, pressure, and other components that could affect the engine. Once the gas meets the required specifications, it passes through the Gas Train and enters the gas engine.

The engine converts the fuel’s energy into mechanical energy, which then drives a Generator or Alternator to produce electricity. A Control Panel and protection system regulate the unit’s operation to match the electrical load.

An efficient system therefore consists of several components, including a gas collection system, gas treatment system, contaminant-removal system, Gas Train, gas engine, Generator, control system, cooling system, and exhaust system.

Why Must Gas Quality Be Improved Before Generating Electricity?

Gas quality directly affects engine efficiency and service life, especially in Biogas systems, where the gas may contain several contaminants, including moisture and hydrogen sulfide, or H2S.

H2S can cause corrosion and accelerate equipment deterioration. Therefore, an H2S-reduction system is usually required before the gas enters the engine. Examples include a Desulfurization Tank or an adsorption system that uses media suited to the specific gas conditions.

One approach is to use Compressed Iron Oxide Pellets in a dry H2S-removal process. Gas flows through a bed of material inside the tank, where the media captures or reacts with H2S under suitable operating conditions.

Tank and media sizing should not be based solely on gas volume. H2S concentration, flow rate, moisture, temperature, and contact time should also be analyzed to ensure that the gas treatment system operates effectively.

Why Is Converting Flare Gas into Electricity Cost-Effective?

The reason Flare Gas to Power is a cost-effective solution for energy and the environment is that it turns energy that might otherwise be wasted into useful electrical power. The economic value of the system depends on gas quantity and quality, operating hours, generator efficiency, and the facility’s electricity-consumption profile.

1. Convert Excess Gas into Energy

If a production process generates gas continuously, using it to produce electricity adds value to an existing resource instead of allowing its energy to be lost through flaring alone.

2. Reduce Electricity Purchases from the Grid

The electricity generated can be used for on-site loads such as water pumps, motors, ventilation systems, aeration systems, cooling systems, and other equipment in factories and farms. This can reduce the amount of electricity purchased from the grid in line with the system’s actual generating capacity.

3. Reduce Long-Term Energy Costs

The value of the system does not depend on the equipment price alone. It should also be assessed based on fuel savings, operating hours, the cost of displaced grid electricity, spare parts, and maintenance expenses. If the site has a sufficient gas supply and a suitable electrical load, a gas-to-power system can support long-term energy-cost management.

4. Connect Waste Management with Energy Production

For farms and factories with wastewater-treatment or organic-digestion systems, producing Biogas and using it to generate electricity creates an integrated connection between waste management and energy production.

5. Use Resources More Efficiently

Recovering gas for electricity generation helps reduce energy losses and, in some cases, can lower dependence on external fuels. However, environmental performance should be evaluated across the entire system—from gas collection and treatment to engine efficiency and exhaust-emission control.

Factors to Consider Before Installing a Gas-Powered Generator

Generator selection should begin with actual site data rather than focusing only on the kW or kVA rating. At least five factors should be reviewed: available gas volume, gas composition, methane content and heating value, H2S level and moisture, and the characteristics of the electrical load.

Operating hours, the cooling system, control system, maintenance requirements, and installation area should also be considered to ensure that the generator can operate continuously and is suited to the actual operating environment.

Biogas Generators for Farms and Factories

For farms and factories that produce biogas, a Biogas Generator Set is another system capable of converting the gas into electricity. Typical applications include pig farms, poultry farms, dairy farms, food-processing plants, and wastewater-treatment systems.

First Technology and Control Co., Ltd. (FTC) provides biogas-powered generator solutions with generating capacities ranging from 20–2,000 kW, according to the company’s information. Its services include design, manufacturing, installation, control systems, maintenance, modification, and overhaul.

Selecting a Biogas Generator or gas-to-power system should therefore begin with a detailed analysis of the site’s gas supply and electrical load. This information is essential for determining the appropriate generator capacity, gas treatment system, and supporting equipment.

Flare Gas to Power is a cost-effective solution for energy and the environment when the system is designed correctly. It is more than simply generating electricity from gas: it recovers available energy, reduces waste, and improves the long-term energy-management efficiency of a factory or farm.

Types of Generators Commonly Used in Agriculture

Generators available on the market can generally be divided into 2 main types based on the type of engine used. Each type has clearly different advantages and limitations:

Gasoline Generator

• Who is it suitable for? Small to medium-sized jobs, applications that require frequent relocation, and intermittent operation rather than long continuous use (around 3-4 hours at a time).
• Advantages: Lightweight, easy to start in cold weather, and generally more affordable to purchase.
• Limitations: Gasoline costs are higher than diesel, and it is not suitable for continuous operation throughout the day or overnight.

Diesel Generator

• Who is it suitable for? Heavy-duty applications, large farms, and operations that require electricity continuously throughout the day and night (such as livestock buildings or large water pumping systems).
• Advantages: Strong and durable, consumes less fuel relative to the amount of power produced, and generally has lower long-term maintenance costs.
• Limitations: The unit is heavier, more expensive than a gasoline generator, and produces more noise (unless it is a soundproof or silent model).

How to Calculate Power Requirements (Watts) Before Buying to Prevent Generator Damage

The most important rule is that you should never choose a generator with a power output that exactly matches the rated power of your equipment. This is because most agricultural equipment, especially equipment with motors, produces a surge of power known as Starting Wattage during startup, which can be 2-3 times higher than normal operating power.

Simple Calculation Formula for Beginners

• Check the wattage (Watt) of all equipment that you want to operate at the same time (this information can usually be found on the equipment label).
• Separate equipment that contains motors. Multiply the wattage of each motor-driven device by 3 to allow for startup power.
• Add all wattages together and then include approximately 20% extra capacity as a Safety Factor.
• Calculation example: If you want to operate a 1,000-watt submersible water pump, the pump may require up to 3,000 watts during startup (1,000 × 3). Therefore, you should choose a generator with a continuous power output of at least 3,500 watts (3.5 kW).

How Much Power Do Common Agricultural Devices Use?

To provide a clearer picture and make it easier to estimate the appropriate generator size, below are approximate power requirements for different types of agricultural equipment:

High Starting-Wattage Equipment (Motors/Pumps)

• Borehole Pump / Submersible Pump (1 HP): Normal power consumption is approximately 750 watts, but startup power can increase to around 2,250 watts.
• Electric Grass Cutter: Normal power consumption is approximately 1,000 – 1,500 watts, but startup power can increase to around 2,000 – 3,000 watts.
• Animal Feed Chopper/Grinder (1.5 HP): Normal power consumption is approximately 1,100 watts, but startup power can increase to around 3,300 watts.

Stable-Load Equipment (No Significant Starting Surge)

• LED Lighting: Uses very little electricity, only around 10 – 50 watts per bulb (simply calculate according to the actual number of bulbs being used).
• Battery-Powered Sprayer (while charging): Uses only around 50 – 100 watts.
• Small Egg Incubator: Uses approximately 100 – 300 watts (power consumption may increase to around 400 watts when the heating system starts).

3 Tips for Using a Generator Safely and Extending Its Service Life on a Farm

• Avoid moisture and rain. Even when the generator is used outdoors, it should always be protected with a simple shelter or roof against sunlight and rain. Never place the generator in an area where water can accumulate, as this may cause electrical short circuits.
• Follow the correct startup sequence. Start the generator and allow the engine to run steadily first. Then connect the equipment with the highest power requirement (such as water pumps) before gradually connecting smaller devices. This helps prevent the generator from being overloaded all at once.
• Do not neglect engine oil. Agricultural generators often operate under heavy loads in dusty environments. Engine oil should be changed strictly according to the recommended service interval (typically every 50-100 operating hours) to help extend piston and engine life.

Conclusion: Which Generator Offers the Best Value and Best Fits Your Farm?

Choosing the most suitable generator for agricultural applications depends on the size of the area and the type of work required. For a small farm where the generator needs to be moved frequently and is used only a few hours per day, a 3-5 kW gasoline generator can provide a practical solution at a more affordable cost. However, for a large farm or closed greenhouse that requires continuous power for high-horsepower water pumps over long periods, investing in a diesel generator rated at 5 kW or higher can help reduce fuel costs and provide significantly better long-term value.

A Biogas Generator Set is a power generation system that uses biogas as fuel to drive an engine, which then transfers mechanical power to a generator to produce electricity.

Biogas primarily consists of methane (CH₄) and carbon dioxide (CO₂), along with other gases and impurities. The composition varies depending on the feedstock and the biogas production process.

How Does a Biogas Generator Work?

Pic

Biogas Generator A biogas generator operates on the same basic principle as other generators powered by internal combustion engines. The main difference is that biogas is used as the fuel instead of diesel or other conventional fuels.

Biogas is supplied to the engine’s fuel system, where it is combusted inside the engine to generate mechanical power. This rotational power is then transferred to the Generator or Alternator to produce electricity.

System performance does not depend solely on the generator’s capacity. Several other factors must also be considered, including:

• Daily biogas production volume
• Methane concentration in the biogas
• Consistency of the gas supply
• H₂S and moisture levels
• Gas pressure before entering the engine
• The farm’s electricity consumption pattern
• Electrical load size and characteristics
• Generator operating hours
• Cooling and lubrication systems
• Generator control and protection systems

For this reason, selecting a biogas generator should involve evaluating the entire system, from the biogas production source to the electrical loads. The generator should not be selected based solely on its kW or kVA rating.

Why Should Livestock Farms Have a Backup Power System?

Livestock farms rely on many types of equipment that need to operate continuously, such as ventilation fans, water pumps, feeding systems, temperature control systems, cooling systems, lighting, and automated control systems.

If a power outage occurs, these systems may stop operating at the same time. Having a backup generator allows essential electrical loads to be supplied with power quickly, particularly on farms where maintaining stable environmental conditions inside livestock buildings is critical.

The system can be designed to operate with an ATS (Automatic Transfer Switch). The ATS monitors the main power supply. When the main power fails, the system automatically signals the generator to start and transfers the electrical supply to the generator according to the predefined sequence.

How to Choose the Right Generator Size for a Farm

Generator sizing should not be based solely on the total rated power of all connected equipment. Certain equipment, such as motors, water pumps, and large ventilation fans, may draw significantly higher current during startup than during normal operation.

Engineers should therefore consider kW, kVA, Power Factor, Starting Current, and the operating characteristics of the electrical loads, as well as the sequence in which equipment is started.

For example, if a farm has large water pumps and a large number of ventilation fans, selecting a generator based only on the equipment’s normal operating power may not be sufficient. The motor starting current must also be evaluated, and an appropriate load sequence should be established.

For biogas systems, the actual volume of biogas produced and the quality of the gas must also be considered to ensure that the engine can operate efficiently and reliably.

Frequently Asked Questions About Biogas Systems on Livestock Farms

The post Biogas Generator Systems for Livestock Farms appeared first on เครื่องกำเนิดไฟฟ้าไบโอแก๊ส.

The answer is: a biogas generator uses biogas as its energy source.

Biogas is produced through the decomposition of organic matter by microorganisms under oxygen-free conditions, a process known as Anaerobic Digestion. The resulting gas mainly consists of:

• Methane (CH₄), approximately 50–70%
• Carbon dioxide (CO₂)
• Water vapor
• Hydrogen sulfide (H₂S)
• Small amounts of other gases

After the biogas has undergone a gas treatment and purification process, the methane-rich gas is supplied to the generator engine. The engine converts the chemical energy in the gas into mechanical energy, which drives the generator to continuously produce electricity for practical use.

What Are the Main Sources of Biogas?

Biogas feedstocks can generally be divided into three main groups:

• Agricultural Waste and Animal Manure
  This includes wastewater from cassava processing facilities, palm oil mills, as well as manure from pig farms, cattle farms, and other livestock operations.
• Organic Waste
  Organic waste includes food scraps and biodegradable waste generated by shopping centers, fresh markets, restaurants, communities, and other facilities.
• Municipal and Industrial Wastewater
  Many types of industrial facilities can produce biogas from wastewater, including food processing plants, sugar mills, cassava starch factories, beverage factories, and palm oil mills. Municipal wastewater and wastewater generated from daily consumption can also be treated through biogas systems. Because these wastewater streams contain high levels of organic matter, they can be suitable feedstocks for biogas production.

How Does a Biogas Generator Work?

Electricity generation from biogas can be explained in three main steps:

1. Anaerobic Digester
   Organic waste is fed into a sealed digester where oxygen is absent. Microorganisms break down the organic matter and produce biogas. The resulting gas typically contains approximately 55–70% methane, along with carbon dioxide and small amounts of other gases.
2. Gas Treatment and Purification System
   Raw biogas cannot normally be supplied directly to a generator engine because contaminants such as hydrogen sulfide and moisture can cause serious corrosion and damage to metal components. The gas must therefore pass through a filtration, scrubbing, and moisture-removal system before it is supplied to the engine. This process improves gas quality and provides cleaner, methane-rich fuel for power generation.
3. Gas Engine Ignition and Electricity Generation
   Once treated, the methane-rich gas is supplied to the combustion chamber of the biogas generator engine. Combustion produces mechanical force that drives the crankshaft. The connected alternator then converts this mechanical rotational energy into electrical energy for use within the facility or electrical system.

Who Should Consider Using a Biogas Generator?

• Livestock farms that generate large amounts of animal manure every day, such as pig farms, poultry farms, dairy farms, and cattle farms.
• Food processing and industrial plants that generate substantial volumes of wastewater or organic residues.
• Large hotels and resorts looking to combine organic waste management with on-site electricity generation.
• Facilities requiring a reliable power supply, particularly in areas where the main electricity grid is unstable.

How to Choose the Right Biogas Generator

Before investing in a biogas generator, four key factors should be carefully considered:

1. Actual Gas Volume and Gas Quality
   The generator engine must be properly sized according to the actual amount and quality of biogas available. Selecting a generator based only on its kVA rating may lead to inefficient operation or insufficient fuel supply.
2. Control System and Generator Control Panel
   Important components may include a Generator Control Panel, ATS Controller, AVR, synchronization system, and SCADA Online system. These systems allow operators to monitor and control generator performance in real time.
3. Reliable Spare Parts Availability
   For major engine brands such as Cummins, Caterpillar (CAT), Perkins, Volvo, and Mitsubishi, access to replacement parts is essential. Reliable spare parts support helps reduce downtime and keeps the generator operating efficiently.
4. After-Sales Service
   Biogas generators are often designed to operate continuously or for extended periods, sometimes nearly 24 hours a day. Without an experienced technical team to maintain the system, a minor problem can develop into a major failure that may stop the entire power generation process.

A generator control system is the processing and command unit that acts as the “brain” of a generator. Its primary function is to monitor the condition of the engine and alternator, as well as control the start and stop operations according to predefined conditions.

Main Functions of the Control Module

• Monitoring Monitors voltage, frequency, and electrical current values.
• Protection Protects the generator from damage caused by issues such as Over Voltage, High Temperature, or Low Oil Pressure.
• Automation Automatically starts the generator when a power outage (Power Failure) occurs.

Types of Generator Control System Installations Commonly Used Today

When selecting a generator control system, businesses can choose based on the suitability of their application as follows:

1. Manual Control Panel  Suitable for backup generators in locations with simple operations or where staff are always available onsite. Users must manually press the Start button and switch the power source themselves.
2. Automatic Mains Failure (AMF) & Automatic Transfer Switch (ATS) This is currently the most popular system. It works together to monitor utility power supplied by the grid (PEA/MEA). When a power outage occurs, the control system automatically starts the generator and transfers the electrical load to the generator within a few seconds.
3. Synchronizing Control Panel Designed for facilities operating multiple generators simultaneously. The control system adjusts the frequency and voltage of each generator to match before sharing the electrical load, ensuring maximum efficiency and fuel savings.

A 3-phase generator is an alternating current (AC) power generation system designed to deliver stable and continuous electrical power at 380–400 volts. Unlike single-phase systems, 3-phase generators use three separate windings that generate electricity simultaneously, allowing them to deliver higher power output and better efficiency.

Because the electrical load is distributed evenly across three phases, power transmission becomes smoother, more stable, and more suitable for heavy-duty industrial applications. This is why most factories, commercial buildings, and large-scale projects rely on 3-phase generators as their primary or backup power source.

Difference Between Single-Phase and 3-Phase Generators

In general, generators are divided into two main categories: single-phase and three-phase systems.

Single-Phase Generator

A single-phase generator typically operates at 220–230 volts with a frequency of 50 Hz. It is commonly used for residential applications and light electrical loads such as household appliances, lighting systems, and small office equipment.

Advantages of Single-Phase Generators

• Easier installation
• Lower installation costs
• Suitable for homes and small businesses
• Ideal for light electrical loads

Limitations

• Lower power capacity
• Less stable for heavy machinery
• Higher long-term operating costs in large-scale applications

Three-Phase Generator

A 3-phase generator operates at 380–400 volts and delivers stronger, more consistent electrical power. It is designed to support high electrical demands and large machinery commonly found in industrial environments.

Because of its stability and efficiency, a three-phase system is widely used in:

• Manufacturing plants
• Commercial buildings
• Hotels
• Shopping malls
• Warehouses
• Construction projects
• Hospitals

Most industrial facilities choose 3-phase electrical systems as the standard because they can handle continuous high-load operations more effectively.

Who Should Use a 3-Phase Generator?

Choosing the right generator size depends on the type of business, power consumption, and operational requirements. Below are the most common generator sizes and their ideal applications.

• Major hospitals
• Large shopping malls
• National infrastructure projects

This generator size is often used as either:

• Primary power supply
• Critical backup power system

for facilities operating continuously 24 hours a day.

Comparison Table of 3-Phase Generator Sizes

How to Choose the Right 3-Phase Generator

Before purchasing a generator, consider the following factors:

• Calculate Total Electrical Load Determine the total power consumption of all equipment and machinery to avoid undersized or overloaded systems.
• Identify Usage Type Choose whether the generator will be used for Standby Power Prime Power Continuous Power Different applications require different generator capacities and configurations.
• Consider Future Expansion If your business plans to expand operations, selecting a slightly larger generator can help avoid future replacement costs.
• Check Installation Space Large generators require proper ventilation, noise control, and sufficient installation area.
• Choose Reliable Control Systems Features such as ATS systems, voltage protection, and remote monitoring improve operational safety and efficiency.

Conclusion

A Cummins Generator is a globally recognized diesel engine and power generator brand from the United States. Founded in 1919 in Columbus, Indiana, Cummins has expanded its manufacturing plants and service centers to more than 190 countries worldwide, including Thailand.

Cummins generators are alternating current (AC) power generators typically powered by diesel engines, although alternative fuel systems are also available. Cummins engines are well known for their durability, high efficiency, and long operational lifespan, making them suitable for a wide range of industrial applications.

These generators can operate as both:

• Standby Power Systems
• Prime or Continuous Power Systems

This flexibility makes Cummins generators ideal for factories, hotels, hospitals, commercial buildings, warehouses, data centers, and large-scale industrial projects.

Types of Cummins Generators

Cummins generators can be categorized based on their primary usage applications.

1. Standby Power

Standby generators are designed to provide backup electricity during power outages. They are ideal for hotels, office buildings, and residential properties.

Key advantages include:

• Automatic startup during power failure
• Automatic shutdown once utility power returns
• Reliable emergency power supply

2. Prime Power

Prime power generators are designed for continuous operation as the primary source of electricity, especially in areas without access to the utility grid.

Common applications include:

• Construction sites
• Remote locations
• Agricultural operations

These generators can operate for long hours without interruption.

Cummins Generator Sizes and Applications

Cummins manufactures generators in a wide range of capacities, from small residential units to large industrial power systems.

How to Choose the Right Cummins Generator Size

Choosing the correct generator size is extremely important. A generator that is too small will overload and wear out quickly, while an oversized generator can lead to unnecessary fuel consumption and higher investment costs.

Follow these steps to select the right generator.

Step 1: Calculate Your Electrical Load

List all electrical equipment that will operate using the generator, such as:

• Air conditioners
• Refrigerators
• Pumps
• Machinery
• Lighting systems

Then calculate the total power consumption in kilowatts (kW).

If the equipment rating is displayed in kVA, convert it using the formula below:

kW=kVA×Power FactorkW = kVA \times Power\ FactorkW=kVA×Power Factor

Typically, the Power Factor (PF) is approximately 0.8.

You should also add an extra 10–20% capacity to handle peak loads safely.

Example

If the total electrical load is 10 kW:

• Add 20% reserve capacity
• Total required power becomes 12 kW
• Recommended generator size: Cummins 12–15 kW

Step 2: Determine the Type of Usage

Different applications require different generator operating modes.

For example:

• A residential backup system may only require a 5 kW generator
• A construction site may require 10–15 kW or more for continuous operation

Step 3: Select the Appropriate Generator Capacity

After calculating your total load and reserve margin, choose a generator slightly larger than your actual requirement.

Avoid choosing a generator that is too small, as it may:

• Overwork the engine
• Increase fuel consumption
• Shorten equipment lifespan

At the same time, avoid excessive oversizing to reduce unnecessary installation and operating costs.

Step 4: Check Technical Specifications

Before purchasing a generator, verify the following technical details:

• Electrical frequency (Thailand uses 50 Hz)
• Voltage system (380/220V or 400/230V)
• Cooling and ventilation system
• Noise level during operation
• Automatic Transfer Switch (ATS) capability for standby systems

Real Calculation Example

Suppose a factory has a total electrical load of 300 kW with multiple machines operating simultaneously.

If the Power Factor is 0.8:

        300÷0.8=375 kVA

in this case, the recommended generator size would be approximately 400 kVA.

If future factory expansion is expected, choosing a larger generator in the range of 450–500 kVA would provide better long-term flexibility.

However, if the generator is intended only for backup power to essential systems, a smaller 300–350 kVA unit may be sufficient.

Another example:

If your total load equals 10 kW:

• Add 20% reserve capacity → 12 kW
• Recommended size → Cummins Generator 15 kW

Professional Tips for Choosing a Generator

• Select a generator slightly larger than your actual power requirement
• Always verify voltage and frequency compatibility
• Choose a Silent Type Generator for residential or office installations
• Install an Automatic Transfer Switch (ATS) for automatic startup during outages
• Work with experienced generator specialists for installation and maintenance
