FIELD: power engineering.
SUBSTANCE: invention relates to the field of power engineering. Method of increasing power of double-circuit NPP due to combination with hydrogen cycle is carried out due to the fact that feed water after cooling channel of hydrogen combustion products in oxygen enters mixing steam-water heater for its heating above rated temperature, but not higher than the boiling point at the given pressure before feeding into the steam generator. Condensed water added to feed water of hydrogen combustion in oxygen after operation in steam-turbine plant are removed from cycle after condenser of steam-turbine plant and directed to tank-accumulator. Some part of products of hydrogen combustion in oxygen is directed to mixing steam-steam superheater. Mixtures of hydrogen to oxygen mixed with superheated steam after operation in steam-turbine plant are removed from cycle after condenser of steam-turbine plant and directed to tank-accumulator.
EFFECT: invention increases efficiency of using hydrogen fuel during its stoichiometric combustion.
