(PDF) THERMODYNAMIC ANALYSIS FOR - …

In a power plant, most of the heat loss is from the high-temperature flue gas leaving the boiler. To minimize these heat losses, two flue gas heat recovery systems are proposed. The waste heat of flue gas is used for regenerative heating in the heater. This reduces steam extraction from steam turbine and more power is generated.

Waste Exhaust Heat Boilers - clarke-energy.com

2019-9-18 · 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 circuits.

HEAT RECOVERY BOILERS - Thermopedia

Heat recovery boilers are also often found in association with high temperature processes such as steel and glass making. It is not uncommon for these boilers to receive additional heat by supplementary firing of other by-products or by burning gas or light oil to raise the boiler inlet gas temperature to a level commensurate with the desired steam conditions.
