METHOD OF VACUUM DEAERATION OF MAKE-UP WATER OF HEATING NETWORK AT THERMAL POWER PLANT

摘要

FIELD: power industry.;SUBSTANCE: method involves heating of source water to 35÷50°C in surface heater, which is then decarbonised, deaerated in vacuum; for that purpose, superheated delivery water is supplied to vacuum deaerator as heating medium, deaerated make-up water with temperature of 50÷60°C is removed from vacuum deaerator to storage tank and then to return pipeline of the heating network. As heating medium in surface heater of source water there used is deaerated make-up water that is supplied after the heater to return pipeline of heating network with temperature of 30÷45°C.;EFFECT: invention allows increasing the electric energy yield on heat consumption due to refusing to use as heating medium for heating of source water prior to vacuum deaeration of high potential steam.;1 dwg
