Title: RETROFITTING COAL-FIRED POWER GENERATION SYSTEMS WITH HYDROGEN COMBUSTORS
Abstract:
A method of retrofitting a power generation system having a coal-fired steam boiler, a steam turbine system, and a condenser comprising installing a hydrogen-fired combustion system therein having the step of 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 steam turbine system. Another method of retrofitting a power generation system has the steps of installing a hydrogen-fired combustion system to receive the steam flow, a hydrogen stream, and an oxygen stream, and to produce a super-heated steam flow therefrom; and installing a new steam turbine system capable of receiving and expanding said super-heated steam flow and directing said expanded super-heated steam flow to at least a portion of said original steam turbine system.
