METHOD OF OPERATION OF HEAT SUPPLY SYSTEM

摘要

FIELD: heat power engineering. SUBSTANCE: heating-system water heated in succession in lower and upper heaters of extraction turbine is fed to consumer; losses of heating-system water are replenished by make-up water which is preliminarily heated and deaerated under vacuum. Heating the make-up water before vacuum deaeration is effected by means of heating-system water taken for this purpose after lower heater of turbine. EFFECT: enhanced reliability and economical efficiency of heat-supply system. 1 dwg
