MODELING AND COST OPTIMIZATION OF COMBINED

2017-12-2 · is combined with a heat recovery and steam turbine system, which operates on the Rankine cycle. The exhaust gas from the gas turbine is nominally at 1000ºF, and it is the source of energy to the heat recovery steam generator (HRSG) to produce superheated steam. In the process, the exhaust gas is reduced to approximately 300ºF.

Victory EnergyGas Turbine Heat Recovery Steam

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. When the hot exhaust enters the HRSG, additional burners are used to further heat a series of water tubes, which generate steam.
