The boiler feed water economizer is basically a gas-liquid heat exchanger located after the boiler evaporator section. The economizer also uses a portion of the energy contained in the thermal oxidizer combustion gases (after the waste heat boiler) to preheat the boiler feed water before it enters the boiler evaporator section.
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

Waste heat is heat that is produced by a machine, or other process that uses energy, as a byproduct of doing work. All such processes give off some waste heat as a fundamental result of the laws of thermodynamics. Waste heat has lower utility (or in thermodynamics lexicon a lower exergy or higher entropy) than the
