Gas generator key benefits
Cost-effective power generationFlexibility to quickly ramp power supply up or down
Exceptional performance and reliability
Reduced environmental impact
Combined heat and power provision
24/7, turn-key service
Reduced environmental impact
Chaiwei Power natural gas generators adopt Jichai or Weichai or Chargewe brand gas engines. These heavy-duty, spark-arrested, turbo-charged, after-cooled engines have a purpose built alternator which is suitable for continuous operation in hash environments. The patented fuel system and advanced engine design ensure emission regulations are met as they are highly efficient with a virtually smoke free operation.
Compared to diesel generators, gas generators have a much lower sulphur, NOx and greenhouse gas emission content.
Combined Heat and Power (CHP) benefits
Chaiwei Power gas power solution allows customers to use heat generated by the natural gas powered units, to produce hot water for the customers own CHP units. This can be vital in many processing environments in creating added saving for the customer. This facility supports combined heat and power
Strategies, without the need for long term capital investment in new plant.

Requirement for Coal mine/bed gas
Within 1m to the intake valve of gas generator set
1.    Gas temperature≤40°C
2.    Pressure 3-20kpa, pressure changing rate≤1kpa/min
3.    H2S≤200mg/Nm³
4.    If the CH4 content less than 30%, the total content of CH4 and O2 should not less than 28%, the content of O2 should not less than 16%.
5.    Moisture content≤40g/N m³
6.    Impurity particle size≤5μm, impurity content≤30mg/N m³
Â
If there are too much sulfur and ammonia in the gas, it will not only corrode the electrode of sparking plug seriously but also increase the acid value of engine oil which will corrode the parts inside of genset, easy to generation sediment and increase the attrition corrosion to the engine.
