FIELD: power engineering.
SUBSTANCE: invention relates to power engineering and is intended for use at double-circuit NPPs with water cooled reactors. Method of hydrogen heating of feed water at NPP, containing hydrogen-oxygen combustion chamber, combustion products combustion path, feed water heaters, feed pump, compressor, tank-accumulator. Mixture of steam additionally generated in steam generator, obtained by heating feed water before steam generator, and hydrogen combustion products in oxygen medium after cooling channel of combustion products is directed to additional steam turbine plant to generate power, note here that condensed steam condensed in condenser is fed into regenerative cycle of main steam-turbine plant while condensed steam from combustion products is directed to accumulator tank. At that, non-condensing gases from combustion products are discharged into atmosphere through special gas purification system.
EFFECT: invention enables efficient and reliable use of hydrogen fuel.
