What Is Generator Set Heat Recovery System?

Generator set heat recovery involves recovering energy from waste heat generated by a generator set to improve overall energy efficiency and reduce waste. This is typically achieved by recovering heat from the engine's exhaust, cooling water, oil, or fuel coolers. This heat can then be used for various purposes, such as district heating, hot water, process heating, and additional power generation. This can increase the overall efficiency of the generator set from approximately 30% to over 80%.

Heat Recovery Principles and Methods

Heat Recovery Sources:

Exhaust: Recover heat from high-temperature exhaust gases.

Jack Water: Extract heat from the engine's cooling water circuit.

Oil and Fuel: Recover heat from the oil lubrication and fuel cooling systems.
