STEAM-GAS UNIT BASED ON NUCLEAR POWER PLANT Russian patent published in 2015 - IPC F01K23/00 F24H7/00 

FIELD: power industry.

SUBSTANCE: steam-gas unit on the basis of nuclear power plant (NPP) is fitted with the gas-steam heat exchanger connected by the heating side to the path of exhaust gases from the gas turbine, and by the heated side - to the steam line between cylinders of the steam turbine parallel to the second step of the steam-steam superheater, by the starting standby boiler room located downstream the gas-water heater and connected at the inlet by the heating side with the exhaust gas pipeline, and downstream - with the pre-heater of chemically cleaned water, on the heated side upstream - with the heater of chemically cleaned water, downstream - with the satellite turbine. The satellite turbine upstream is connected to the starting standby boiler room, and downstream - to the satellite turbine condenser. The unit of preparation of foreign steam comprising the steam electrolyser unit, oxygen storage, hydrogen storage, an oxygen compressing unit, a hydrogen compressing unit, a hydrogen and oxygen steam generator connected upstream with the steam withdrawal from the high pressure cylinder of the steam turbine, and downstream - with the pipeline of steam withdrawal from the high pressure cylinder of the steam turbine on the first step of the intermediate steam overheat and on the steam mixer which upstream is connected to the starting standby boiler room and the unit of preparation of foreign steam, and downstream - with the satellite turbine and the steam line substituting the steam withdrawal from the steam turbine, the heater of chemically cleaned water connected upstream by the heating side to the exhaust gas pipeline located downstream the starting standby boiler room, and downstream - with the chimney, and by the heated side upstream - with the pipeline of chemically cleaned water, downstream - from the starting standby boiler room.

EFFECT: increase of capacity and manoeuvrability of steam-gas unit.
