Victory EnergyGas Turbine Heat Recovery Steam

One such way is through the implementation of Gas Turbine Heat Recovery Steam Generators or, GT-HRSGs. As its name alludes to, Heat Recovery Steam Generators take the heat that would otherwise go unused and generates steam. As exhaust heat leaves a gas turbine it enters the HRSG.

Heat Recovery Steam Generators (HRSG) | Boilers -

2019-6-20·A heat recovery steam generator (HRSG) is one of the major pieces of equipment in a gas turbine combined cycle power plant that boasts a high thermal efficiency and produces minimal CO 2 emissions. An HRSG is a kind of heat exchanger that recovers heat from the exhaust gases of a gas turbine to an extreme degree.

Types of Heat Recovery Steam Generators (HRSG)

Normally HRSGs do not have any additional heat input. The performance and output of the HRSG is dependent on the exhaust heat of the gas turbine. At part loads, this leads to reduced output from the HRSGs. In addition, ambient conditions also affect the Gas Turbine performance. This could affect the downstream process were the steam is used.
