Abstract
A waste-to-energy plant which is designed and operated to burn municipal waste (in 2) combines a high pressure steam turbine/generator cycle and a combustion turbine/generator cycle, wherein the exit gas from the combustion turbine (6) is utilized to superheat (in 4) high pressure steam (from 2) prior to entering the steam turbine (8). The combination of the combustion turbine/generator cycle with the steam turbine/generator cycle enables operation of the waste-to-energy plant at high pressure and high temperature resulting in greatly increased thermal cycle efficiency while eliminating superheater surfaces from the waste heat recovery boiler, thereby greatly reducing corrosion problems associated with waste heat recovery boilers.
