HYDROGEN COMBUSTION SYSTEM FOR HYDROGEN HEATING FRESH STEAM IN A CYCLE OF A NUCLEAR POWER PLANT

摘要

1. A hydrogen combustion system for steam-hydrogen superheating of live steam in a nuclear power plant cycle, including a hydrogen-oxygen steam generator with an ignition device, oxidizer (oxygen) and fuel (hydrogen) supply lines, a hydrogen-oxygen combustion chamber of the initial nonstoichiometric oxidation, afterburning a hydrogen-oxygen combustion chamber stoichiometric oxidation, characterized in that the combustion of hydrogen in oxygen in the afterburning hydrogen-oxygen combustion chamber of stoichiometric oxidation is carried out by self-ignition with the formation of high-temperature steam and its subsequent mixing with fresh steam from the turbine, which simultaneously serves as a cooling medium of the afterburning hydrogen-oxygen combustion chamber of stoichiometric oxidation. ! 2. The system according to claim 1, characterized in that the hydrogen-oxygen combustion chamber of the initial non-stoichiometric oxidation with an ignition device is located separately from the afterburning hydrogen-oxygen combustion chamber of the stoichiometric oxidation and communicated with it by a connecting pipe.
