Abstract
A power plant () including a boiler unit portion () and a gas turbine unit portion () operable in multiple modes, including operation of the boiler unit portion independent of the gas turbine unit portion. Exhaust gas from the gas turbine is cooled in a heat recovery steam generator (HRSG) () where steam is produced. The exhaust gas may also be provided to support combustion in a separately fueled boiler (). The exhaust gas may be extracted from any location within or downstream of the HRSG. Steam produced in the HRSG and/or in the boiler may be supplied to a steam turbine unit (). Dampers () are provided to selectively direct the gas turbine exhaust to the boiler or to bypass the boiler. An existing boiler fired steam power plant may be reconfigured to have the described arrangement.
