Combined-cycle power plant operate by integrating a combustion turbine generator (CTG) and heat recovery steam generator (HRSG) with a steam turbine generator (STG). On some combined-cycle plants, the isolation of the CTG/HRSG from the STG is provided by the application of an HRSG bypass damper and bypass stack. In this case steam generation in the HRSG can be controlled/eliminated by venting the CTG exhaust gas through the bypass stack. This scheme facilitates simple-cycle operation and avoids condensate loss, but it is capital intensive and presents the problem of noise pollution.
