600kw Biogas Generator for Waste Sites

The durable 600kW Biogas Generator for Waste Sites is engineered by Kecheng (Shandong Kecheng Electric Power Equipment Co., Ltd., China) specifically for municipal landfills, industrial waste lagoons, and transfer stations. Unlike standard generators that fail on high‑H₂S or siloxane‑laden gas, this unit includes a two‑stage gas cleaning train: an iron‑oxide desulfurizer (H₂S from 1,500 ppm down to ≤200 ppm) followed by an activated carbon vessel that adsorbs siloxanes and VOCs. The engine uses hardened valve seats and a closed crankcase ventilation system to survive acidic conditions. The PLC automatically derates when CH₄ dips below 45% and logs hourly gas composition – data required for carbon credit verification (CDM, VCS). The optional exhaust heat exchanger heats leachate tanks or buildings, pushing total efficiency above 80%. Price includes on‑site commissioning, operator training, and a 2‑year warranty.

Process Flow

From Landfill Gas to Electricity

Landfill gas well → Condensate knock‑out drum →

Iron‑oxide desulfurizer → Activated carbon siloxane filter →

Gas pressure regulator → Engine + Alternator →

Heat exchanger (optional) → Grid or site load

Key process notes

- Condensate knock‑out – removes water droplets that would foul desulfurizer media. Automatic drain every 2 hours.

- Desulfurization – two vessels (one online, one standby). Changeover takes 10 minutes without shutdown.

- Siloxane removal – activated carbon adsorbs siloxanes; exhausted carbon is non‑hazardous and can be sent to a cement kiln.

- Engine – lean‑burn, spark‑ignited, turbocharged. Compression ratio 11.5:1 (lower than pure biogas units to tolerate methane fluctuations).

- Heat recovery (optional) – captures jacket water and exhaust heat to warm leachate tanks or buildings, raising total efficiency to 80%.

Frequently Asked Questions

Q: How do siloxanes damage the generator, and what is your solution?  

A: Siloxanes (from aerosols, cosmetics, packaging) burn into abrasive silica that grinds valves and pistons. Our standard activated carbon filter removes >95% of siloxanes. A differential pressure gauge shows when to replace the carbon – typically every 3,000 hours. For high‑siloxane sites, we offer a dual‑vessel carbon filter for online changeover.

Q: What H₂S level can this generator tolerate?  

A: The iron‑oxide desulfurizer reduces H₂S from up to 1,500 ppm down to ≤200 ppm at the engine inlet. For sites with H₂S >1,500 ppm, we supply a biological scrubber that cuts H₂S to 50 ppm. The engine oil analysis kit is included for the first year to monitor acid buildup.

Q: Can it handle fluctuating methane content without shutting down?  

A: Yes. The PLC accepts CH₄ as low as 40% and automatically reduces load to match gas quality. If CH₄ drops below 38% for 5 minutes, the unit goes into standby and restarts automatically when gas recovers. No manual reset needed.

Q: How does this generator help with carbon credit reporting?  

A: The control panel logs hourly gas flow, CH₄%, engine hours, and power output. Data is stored for 12 months and can be exported as CSV files. This meets the monitoring requirements of CDM (ACM0001) and VCS methodologies. We also provide a template for annual emission reduction calculations.

Q: What maintenance differs from a standard biogas generator?  

A: Oil changes every 400 hours (vs 500 hours) due to residual H₂S. Siloxane carbon replacement every 2,000–4,000 hours depending on loading. Desulfurizer media replacement every 2,000 hours at 1,500 ppm inlet. All other intervals (spark plugs, valve check) are the same as standard units.

Q: Is the generator suitable for extreme weather?  

A: Standard enclosure IP54 (dust/rain). For coastal sites, IP65 with stainless steel external parts. For sub‑zero climates, a heated enclosure with thermostatic control is available. All options include a corrosion‑resistant exhaust manifold.
