Heat Recovery Steam Generators (HRSG) | GE Gas Power

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.

Options for Improving the Efficiency of Heat Recovery

A combined combustion and steam turbine power plant which includes a steam turbine unit, a boiler unit for supplying steam to the steam turbine unit, and a combustion turbine unit with an exhaust gas duct structure for supplying the turbine exhaust gases to the boiler unit, has at least one heat recovery steam generator arranged in the exhaust gas flow downstream of the boiler unit and

HRSGs for small plants - Rentech Boilers

Sep 09, 2019 · As another, the ASME Boiler and Pressure Vessel Code did not require performance of fatigue analysis during the design process. Most designers and owner/operators projected ongoing baseload operation. Beginning in 1998, Anderson (then with Florida Power Corp) and others began studying the temperature impacts on HRSG tubes, pipes, and headers.

Maintaining High Combined Cycle HRSG Efficiency and

The HRSG is defined as an energy recovery heat exchanger that recaptures heat from a hot gas stream. The steam is generated to drive a steam turbine. A combined-cycle power station (CC) is a common application for an HRSG, where the hot exhaust gas produced from a gas turbine is fed to an HRSG to produce steam to drive a steam turbine (Fig. 5).

Welcome To Combined Cycle Journal

The low exhaust gas temperature from gas turbines, typically ranging from 900 to 1050F, generates less steam on unit gas mass basis in the HRSG evaporator compared to a package boiler. On the other hand, in a steam generator or package boiler, the flue gas stream is cooled from adiabatic combustion temperature of 3300 F and hence generates a
