Abstract:
In a power generation system comprising a coal-fired steam boiler, a multi-stage steam turbine system, and a condenser a method of retrofitting comprising the steps of:a. replacing the coal-fired steam boiler with a hydrogen-fired combustion system such that a steam flow generated by the hydrogen-fired combustion system is directed to the multi-stage steam turbine system,b. connecting a steam/water flow, a hydrogen stream, and an oxygen stream to said hydrogen-fired combustion system,c. connecting a water flow to an inlet of an enclosed water manifold of a heat exchanger between stages of the multi-stage steam turbine system to transfer thermal energy from a first stage of the steam turbine system to a steam/water flow and to a second stage of the steam turbine system, andd. connecting said steam/water flow to a steam/water outlet of said enclosed water manifold, wherein said water flow is connected to the condenser.
