Power 101: Flue Gas Heat Recovery in Power Plants, Part I

Supplementary firing sometimes is installed to boost steam flow, such as on a boiler designed to recover heat from a 1.5-MW GT installed at a college on the West Coast. The unit makes 10,000 lb/hr of steam on exhaust gas alone, double that with the duct burner in operation. The majority of Rentech's jobs are for saturated-steam service.

Options for Improving the Efficiency of Heat Recovery

A heat recovery steam generator ( HRSG) is an energy recovery heat exchanger that recovers heat from a hot gas stream, such as a combustion turbine or other waste gas stream. It produces steam that can be used in a process ( cogeneration) or used to drive a steam turbine ( combined cycle ).

An HRSG is a kind of heat exchanger that recovers heat from the exhaust gases of a gas turbine to an extreme degree. The heat is recovered in the form of steam which is served as the power source of a power-generating steam turbine. For the heat-transfer tubes of an HRSG, finned tubes with excellent heat-transfer performance are employed.

Jul 13, 2009 · 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.

Flue Gas Waste Heat Recovery Steam Generation Exhaust Gas

The steam flow from a heat recovery boiler can usually be increased by the addition of an economizer to preheat the feedwater before it enters the evaporator. The impact of adding an economizer to the evaporator previously analyzed in Fig. 3.1 is shown in Fig. 3.2.The gas temperature leaving the system is reduced substantially and the steam flow is increased approximately 75%.
