Waste Heat Recovery System (WHRS)

The primary source of waste heat of a main engine is the exhaust gas heat dis-sipation, which accounts for about half of the total waste heat, i.e. about 25% of the total fuel energy. In the standard high-efficiency engine version, the ex-haust gas temperature is relatively low after the turbocharger, and just high

Difference Between Heat Recovery Steam Generators (HRSG

Heat Recovery Steam Generator's (HRSG's) are waste heat boilers. The steam turbine or a downstream process uses the steam. The term HRSG refers to the waste heat boiler in a Combined Cycle Power Plant. In its basic form these are bundles of water or steam carrying tubes paced in the hot gas flow path. These recover the heat from the gas to generate superheated steam, hence the name Heat Recovery Steam Generator.
