Auxiliary Boiler Exhaust Coal Heated

Waste Heat Boilers - Clarke Energy

Waste Exhaust Heat Boilers. Approximately 25% of the usable energy of the fuel gas is released in the exhaust of the gas engine. This can be captured for cogeneration in a combined heat and power plant. This heat exits the engine at ~450 o C as ‘high grade heat’, contrasting to ‘low-grade heat’ available from the generator cooling
