Biogas Cogeneration Combined Heat & Power

Biogas cogeneration combined heat and power utilize biogas engine to power the whole unit.

The biogas cogeneration combined heat and power is consisted 1 set bio-gas electrical generator, 1 control cabinet, 1 inter-cooler heat recovery system, 1 jacket water heat recovering system and 1 exhaust heating boiler. Jacket heat are gathered before exporting; exhaust are gathered before discharged.

All electricity are gathered for output. Besides, to ensure normal operation of generators, jacket and inter-cooler heat recovery systems are equipped with emergent cooling system, which includes:

plate heat ex-changer - 1 set

intelligent high temperature circulation pump - 1 set

intelligent temperature-controlled water mixing valve (programmable) - 1 set

Expansion pipe - 1 set

Coolant pressure and level monitor - 1 set

Pressure release valve - 1 set

Jacket water emergency heat ex-changer - 1 set

Inter-cooler emergency heat ex-changer - 1 set

Details of Biogas Cogeneration Combined Heat & Power

Based on client’s requirement and fuel conditions, S250CG (Styer engine) gas engines are selected for the 200kW biogas CHP plant cogeneration. This engine is widely used in natural gas and bio-gas power generation and it is well-known for its performance and reliability.

1) The generator set use gaseous fuel as its power resource and through spark ignition engine to convert thermal power to electricity. Cooling system, lubrication system, fuel supply system, control system, power output system, synchronization system, heat recovering system and base plate are equipped. It is an integrated electrical output equipment and it also accepts various gaseous fuel.

2) Gas engine is connected with alternator SAE flywheel housing through a torque elastic coupling and then been installed on a solid base plate. Shock mitigation system is also installed to avoid shake during operation.

3) Gas valve set, which includes manual globe valve, pressure gauge, filter and pressure regulating valve, is integrated on the base plate.

4) Gas Engine

Proved gas engine is controlled by imported gas close-loop lean-burn control system which includes high energy ignition system, gas-exclusive speed regulator, fuel flow rate control valve, variable Venturi mixture. The system is also optimized by our company to achieve high reliability and efficiency.

5) Alternator

Reliable and efficient mported brushless self-excited AC synchronized alternator is selected.

6) Jacket Water Heat Recover System

The heat ex-changer is SS brazing plate heat ex-changer.
