Biogas Generator

Kecheng is the biogas generator manufacturer you can trust when procuring sustainable power solutions. It transforms organic waste into reliable electricity for farms, industrial facilities, and emergency applications. By integrating gas pretreatment, engines, and power generation modules, these systems ensure efficient, stable output under varying biogas compositions. The product range also includes emergency generator, farm biogas generator, biogas generator sets, etc.

Product working principle and composition

The biogas generator uses biogas produced by fermentation of various organic wastes as fuel. After desulfurization, dehydration and pressure stabilization, the biogas enters the gas engine. In the engine, biogas is mixed with air and burned, and the heat energy generated drives the piston to reciprocate, converting the heat energy into mechanical energy, which in turn drives the generator connected to it to operate and generate stable electricity. The whole system usually covers key parts such as biogas pretreatment device, gas engine, generator and heat recovery equipment. The components work together to ensure efficient and stable power generation process.

Key Advantages

1. Fuel Adaptability

o Maintains stable power output despite changes in biogas composition (±10% per minute)

o Fast-response electronic control systems adjust combustion dynamically

2. Robust and Corrosion-Resistant Design

o Stainless steel, alloy components, and anti-corrosion coatings minimize hydrogen sulfide damage

o Pretreatment removes moisture and sulfur, reducing engine wear and extending service life

3. Operational Efficiency and Support

o Spare parts availability: 95% stocked locally within 24 hours

o Low service cost, reducing operational expenditure

o Compatible with Emergency Generators and diesel units for hybrid setups

FAQ

1. Q: Our raw material composition is complex and the biogas output/concentration is unstable. Can the unit operate stably?

A: The key lies in pretreatment and unit control. Professional pretreatment system (such as precise oxygenation biological desulfurization + buffer pressure stabilization tank) is the guarantee. High-quality units like Kecheng have wide concentration adaptability and fast-response electronic control systems, combined with reasonable gas tank buffering, which can effectively cope with fluctuations.

2. Q: How to get policy subsidies? Are there specific requirements for units?

A: Subsidy policies vary from place to place and from time to time (Development and Reform Price, Energy, Environmental Protection and other departments). Usually, the unit is required to pass the certification of an authoritative organization (efficiency, emissions), meet the grid connection specifications, and complete the project approval and filing. Choosing a brand like Kecheng that is familiar with local policies can get more professional application guidance.

3. Q: How to solve the hydrogen sulfide corrosion problem?

A: Double insurance: The front-end pretreatment must meet the standard (target <200ppm); the unit adopts anti-corrosion coating, stainless steel material, special alloy gas valve seat and other enhanced designs. When signing the contract, clearly specify the guaranteed value of H₂S content and the liability clause after exceeding the standard.
