500kw Biogas Generator for Energy Reuse

Kecheng Power Equipment Co., Ltd. is a professional Manufacturer and Supplier of the 500kw Biogas Generator for Energy Reuse. Based in Weifang, Shandong, we operate a full production line with a registered capital of 18 million RMB and an annual capacity exceeding 5,000 units. Unlike traders, our factory controls every step—from engine assembly to intelligent electrical system manufacturing—ensuring data integrity and mechanical reliability for waste-to-energy projects.

Frequently Asked Questions

Q1: What methane (CH₄) concentration is required for your 500kw biogas generator to operate stably?

A: Our  Biogas Generator operates reliably within a methane range of 40% to 75% . The gas mixer automatically adjusts the air-to-fuel ratio. Below 40% CH₄, we recommend biogas enrichment or pre-treatment. Above 75%, derating is not required.

Q2: Do you provide desulfurization equipment with the generator?

A: Yes. Based on our ISO14001-certified production process, we supply an integrated desulfurization pre-treatment system to remove H₂S before combustion. This protects the engine block and extends component life to 15+ years. We size the desulfurization tower according to your biogas H₂S concentration (typically 500-3000 ppm).

Q3: Can this unit run on pure diesel or natural gas as a backup fuel?

A: Yes. The 500kw Biogas Generator for Energy Reuse can be configured as a dual-fuel unit (biogas + diesel) or a single-fuel unit (biogas only). If your biogas supply fluctuates, the dual-fuel version automatically switches to diesel backup. This follows our standard diesel generator platform (20kW-3000kW) using Cummins, Volvo, Yuchai, or Weichai base engines.

Q4: What is the payback period for a 500kw biogas CHP project?

A: Based on factory case studies and current electricity prices (USD 0.10-0.15/kWh), the payback period for our 500kw Biogas Generator with heat recovery is typically 2.5 to 3.5 years. Without heat recovery, it extends to 4-5 years. We provide a free customized payback calculation with your local utility rates and gas composition.

Q5: Do you offer training for local operators?

A: Yes. Our “during-sale” service includes on-site training covering:

Daily startup and shutdown procedures

Gas mixer adjustment for varying methane content

Desulfurization system maintenance

Fault code reading and basic troubleshooting

Heat recovery system monitoring

Future-Proofing & Carbon Trading

Investing in the 500kw Biogas Generator aligns with global ESG goals. By replacing fossil fuels, your facility qualifies for carbon credit accumulation. Our catalytic technology (solid solution structure optimization) ensures stable combustion even at low methane peaks, preventing flaring waste. We provide emission reports required for CDM (Clean Development Mechanism) registration.

Technical Engine & Core Components

Our production facility utilizes complete inspection equipment to assemble the 500kw Biogas Generator for Energy Reuse. We adapt internal combustion engines (original brands: Cummins, Volvo, Deutz, or Yuchai) specifically for biogas's slow combustion speed.

- Combustion System: Modified ignition system with a gas mixer to optimize the air-to-biogas ratio (ensuring complete combustion and reducing methane slip).
- Desulfurization Pre-treatment: Integrated pipeline design to remove H₂S before combustion, protecting the engine block from corrosion.
- Speed Control System: Ensures stable voltage during independent grid operation or island mode.
- Heat Recovery Unit: Recycles cooling water and exhaust waste heat for anaerobic digester heating or facility cooling (CHP).

Why Achieve Over 80% Total Efficiency? 

Standard power generation averages only 35-40% electrical efficiency. The remaining energy is lost as heat. Our Biogas Generator captures this byproduct.

Production Line & Quality Assurance

We are not an assembly workshop. Our 18 million RMB facility includes intelligent electrical system manufacturing and 100% load-bank testing before shipping.

- Certifications: ISO9001-2000 (Quality) & ISO14001 (Environmental).
- Testing Protocol: Every 500kw Biogas Generator for Energy Reuse undergoes a 4-hour full-load test, including a 30-minute overload test (110%).
- Component Sourcing: Alternators from Stamford/Marathon; Gas engines adapted from Volvo/Cummins/Weichai.
- Anti-corrosion Treatment: Special coating for biogas H₂S environment, extending lifespan to 15+ years.

Application Scenarios 

We design this Biogas Generator  for specific high-waste environments:

- Livestock Farms (Piggeries/Cattle): Converts manure waste into electricity for farm operations + heat for fermentation tanks.
- Landfills & Wastewater Plants: Uses methane gas (otherwise flared) to power blowers and pumps, reducing grid dependence by 60-80%.
- Industrial Factories (Food/Breweries): Treats industrial organic wastewater to generate baseload power for production lines.
- Rural Distributed Energy: Replaces diesel generators with biogas, providing "Carbon-Neutral" backup power.

Why Kecheng as Your B2B Partner?

Drawing from our experience supplying China Construction First Group and China Railway Eighth Bureau, we provide transactional safety.

- Experience: 15+ years in power generation; specifically adapted biogas engines since 2018 using non-noble metal catalysts (Ni-CeCaO3/Al2O3) to reduce production costs.
- Authority: Located in "City of Power" (Weifang). We manage 5 series and 100+ specifications, including parallel units for grid connection.
- Trustworthiness: 24-hour after-sales response. Spare parts stock for 10 years. We do not use "standby price baiting."
