METHOD OF HEAT POWER PLANT OPERATION

摘要

FIELD: heating. ^ SUBSTANCE: invention is designed to utilise heat from blow-off water and can be used in heat power engineering. Generated in boiler, steam is supplied to steam turbine, and additives accumulated in boiler water are drained from boiler together with blow-off water. Blow-off water is used as heating medium in water-to-water heat exchanger. Feed water being supplied to boiler will be heated in regenerating heaters by steam resulted from turbine bleeding. Condensate from the last in feed water line high pressure regenerating heater is used as medium heated in heat exchanger connected to blow-off water pipeline. After condensate heating in water heat exchanger, it is pumped into feed water pipeline between the first and second stages of boiler feed water heater. ^ EFFECT: improvement of heat power plants operation economy and ecology. ^ 1 dwg
