ABSTRACT:
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.
