As a leading manufacturer, supplier and exporter in China, Kecheng provides high-quality biogas generators, mainly including emergency generators, pig farm biogas generator sets, biogas generator sets, etc.
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.

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.
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.
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.
In the field of domestic biogas power generation, Kecheng has accumulated a good reputation with solid research and development and in-depth understanding of the characteristics of Chinese biogas. If you want to know more, please email us or call 13583635366.
