摘要： 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.

摘要： A power plant that combusts hydrogen with oxygen in a high pressure combustor to produce steam, which is mixed with cooling steam before being sent to a high pressure expander, which expands the steam and generates rotating shaft power. The expanded steam is mixed with steam from the combustion of hydrogen and oxygen in an intermediate pressure combustor and expanded in an intermediate pressure turbine, thus generating more rotating shaft power. The steam from the intermediate pressure turbine is fed into a heat recovery steam generator that cools the steam and heats water streams to form cooling steam for at least one of the turbines and the combustors. The now cooled steam exits the steam generator and passes through a low pressure turbine, thereby generating more rotating shaft power, and is condensed into the water streams for heating into cooling steam in the steam generator.
