Reheat Cycle Advantage in Thermal (Steam) Power

2020-12-28 · In the reheat cycle, the steam is extracted from the suitable point in the turbine and is reheated with the help of the flue gases in the boiler furnace. The main purpose of reheating is to increase the dryness of the steam passing through the lower stages of the turbine. The dryness fraction coming out of turbine should not be less than 0.88.

Gas--steam turbine combined cycle power plants

2021-1-1 · To date, most of the applications of combined cycles have been for electric power generation only. The basic gas--steam turbine combined cycle consists of: (1) a gas turbine-generator set, (2) a waste-heat recovery boiler in the gas turbine exhaust stream designed to produce steam, and (3) a steam turbine acting as a bottoming cycle.
