Combined gas turbine steam plant - has overheating device for saturated steam coupled to steam generator

摘要

The steam plant has a coal-fired reactor and a steam generator for cooling the reactor process gases, which are then fed to the combustion chamber of the gas turbine set. The steam generator provides saturated steam which is fed to a further over heating vessel (8') for overheating the saturated steam and having its own burner . Pref. the auxiliary burner for the overheating vessel (8') is positioned in the exhaust line of the gas turbine, for combustion of the process gases. ADVANTAGE - Eliminates corrosion problems.
