Abstract:
A method of operating a power generation plant, comprising:supplying steam to a steam turbine unit such that an exhaust steam is expelled from the steam turbine unit;operating a stabilizing burner at an upstream position in a waste heat recovery boiler during at least one of a start-up period of operation of the power generation plant so as to create steam when an operation of the power generation plant is started and a speed-increasing period of operation of the power generation plant so as to created steam when a speed of the power generation plant is increased;generating steam in the waste heat recovery boiler, said steam generation including using waste heat from a gas turbine having a high temperature portion with a cooling component; andcooling the high temperature portion of the gas turbine by channeling at least one of a portion of the exhaust steam from the steam turbine unit and a portion of the steam generated in the waste heat boiler through the cooling component of the high temperature portion of the gas turbine.
