초록

In a combined cycle system including a gas turbine, a steam turbine and a heat recovery steam generator (HRSG), wherein gas turbine exhaust gas is used in the heat recovery steam generator for heating steam for the steam turbine, the gas turbine exhaust gas flowing from an entry end to an exit end of the HRSG, and wherein the HRSG includes at least one high pressure evaporator arranged to supply steam to a superheater including multiple passes including a first pass at one end thereof adjacent the evaporator, and a final pass adjacent an opposite end the...

청구항

[ What is claimed is:] [11.] A method of controlling temperature of superheated steam in a heat recovery steam generator which includes at least one evaporator and a superheater having first and second opposite ends thereof and one or more intermediate passes therebetween, the method comprising the steps of:a) extracting superheater steam from the first end of the superheater in the heat recovery steam generator;b) conducting the extracted steam outside the heat recovery steam generator; andc) reintroducing the extracted steam into the heat recovery stea...
