FIELD: heat power engineering. ^ SUBSTANCE: proposed thermal power station employs type T extraction turbine with heating steam extractions including seven steam extractions in regeneration system to first three extractions of which three high-pressure regenerative heaters are connected, and to last four extractions four low-pressure regenerative heaters are connected, upper and lower system heaters connected by heating medium line to sixth and seventh steam extractions, respectively, condenser, additional feed water vacuum deaerator connected by additional feed water pipe to higher pressure deaerator between which steam-water heat exchanger is installed being placed in additional feed water pipeline and connected to fifth steam extraction of type T turbine. ^ EFFECT: improved reliability and economy of thermal power station owing to provision of technologically required heating of additional feed water after vacuum deaerator delivered into higher pressure deaerator using stable source of low-grade heat. ^ 1 dwg |
