FIELD: power engineering.SUBSTANCE: steam generation plant of a single-circuit nuclear power plant comprises a reactor, a water heating section, a steam superheating section, a turbine, a power generator, a condenser, a condensate pump, a circulating pump, a unit of make-up water supply, a vortex steam generator connected at the inlet to a section of water heating, with its supply in the reheated condition, and at the outlet - to the pipeline of the steam superheating section. By setting of certain fluid parameters at the inlet to the vortex steam generator, the speed of steam bubbles floating in the swirling chamber may be increased at least several times, and thus to increase specific steam production per unit of evaporation mirror surface, which, in its turn, will make it possible to reduce dimensions of the steam generation plant. Transfer of the process of partial water evaporation from the heating zone in the nuclear reactor into the zone of swirled fluid of the vortex steam generator makes it possible to eliminate flow pulsations in the zone of fluid heating, which helps to increase reliability to plant operation.EFFECT: higher efficiency and reliability of a steam generation plant, possibility to work both on Earth and under zero gravity.1 dwg |
