Natural Gas Generator 250kw / 312.5KVA

1). Engine
Ruichang series natural gas generators are adopt the Cummins gas engine with Stamford brand alternator. And Cummins gas engine adopts the America ignition system and pottery rotate high power lead spark plug.

We also have expanded our business to provide one-stop solution for biogas powered plant based on landfill, food waste, animal manure and waste water.

Genset working condition:

A. Acceptable working conditions
Ambient temperature: -10~+40º C
(antifreeze or preheater needed for below 0º C)
Relative humidity: <90%(20º C)
Altitude: ≤ 1000m
B. Normal working conditions
Gas gensets can run at rated power on the conditions:
Atmospheric Pressure: 100kPa
Ambient Temperature: 20º C
Relative Humidity: 30%
C. Applied gas
Natural Gas, Biogas, LPG, Landfill gas, Oil gas, Syngas, Coal mine gas

Acceptable fuel gas pressure: 5~12kPa
CH4 content: For natural gas ≥ 85%; For biogas ≥ 55%
Gas heat value ≥ 5500kcal/Nm3 (23MJ/Nm3 ).
(Genset output power will increase as the gas heat value increase, if use low heat value gas for fuel (Heat value<5500kcal/Nm3, it will lower the power efficiency. )
Gas doesn't include free water or free materials (the size of impurities should be less than 5μ M. )
