Difference Between Heat Recovery Steam Generators (HRSG

Jan 20, 2017 · The evaporator of heat recovery boiler can be of natural or forced circulation type. The heat exchanger type of the evaporator can be any of parallel-flow, counter-flow or cross-flow. In parallel-flow arrangement the hot and cold fluids move in the same direction and in counter-flow heat exchanger fluids move in opposite direction.

Heat recovery steam generator - Wikipedia

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.

What is a Boiler Heat Exchanger | How Does a Heat

Heat Recovery Steam Generator (HRSG) is a boiler that utilizes heat energy of residual exhaust gases from gas turbine unit to heat water and convert it into steam, and steam is then used to drive steam turbines. In general, Heat Recovery Steam Generator (HRSG) boiler is not equipped with burners and do not consume fuel, so there is not radiation heat transfer process.

Jul 13, 2009 · The main application of the (Heat Recovery Steam Generators) HRSG is in Combined Cycle power plants. In these plants the power generation from the Rankine cycle part, ie. the steam turbine, is around one third of the total power generated . HRSG's produce the steam for this. Classification of HRSG's is on application, design, or operation.

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%.
