METHOD OF HEATING AT STEAM HEAT EXCHANGERS AND PLANT TO THIS END

摘要

FIELD: power engineering.SUBSTANCE: invention relates to power engineering. Method of heating at steam heat exchangers by means of stepwise heating of medium in heat exchangers at several steps by steam with pressure increased at every step and fed to heat exchangers via steam lines and steam condensate discharge from heat exchangers via pipes of every step via condensate discharge devices. Note here that boiler room or thermal power station stem is used at every stage for heating of said heat exchangers. Before feeding to heat exchanger said steam is mixed by injection in jet compressor with steam resulted from condensate self-evaporation. Note here that condensate is discharged from heating first stage condensate discharge while a portion of discharged condensate is injected into steam after jet injection. Invention covers also the plant for implementation of said method.EFFECT: lower steam consumption, production of high-purity condensate and longer life of heat exchange pipes.4 cl, 1 dwg
