Description


STONE brand cummins 250KW Natural Gas Generator

cummins natural gas generator

Shanghai Stone Diesel Engine Co.,LTD

 

Cummins gas engine, durable and high efficiency, CE approved, hot sale in Europe market.               

 

250KW Natural Gas Generator / Gas Generator Set / Gas power generator  

 

 

Genset working condition:

lAcceptable working conditions:

Ambient temperature : -10°C~+40°C

(antifreeze and water heater needed for below 0°C)

Relative humidity:< 90% (20°C)

Altitude:≤ 500m

 

l Normal working conditions:

Genset can run at rated power on the conditions:

Atmospheric Pressure: 100kPa, Ambient Temp: 20°C, Relative Humidity: 30%.

 

lApplied gas:

    Natural Gas, Biogas, LPG, Landfill gas, Oil gas, Syngas, Coal mine gas

 

Acceptable fuel gas pressure: 8~12kPa

CH4 content: for natural gas85% CH4 content: for biogas55%

Gas heat value5500kcal/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 5μm.)

H2S content≤200mg/Nm3

NH3 content≤20mg/Nm3

Impurities content≤30mg/Nm3;size≤5μm

Water content≤40g/Nm3, no free water.
