METHOD OF OPERATION OF PEAK-LOAD HOT-WATER BOILER PLANT Russian patent published in 2002 - IPC

FIELD: heat-power engineering; preparation of make-up water for heating systems. SUBSTANCE: method of operation of peak-load boiler plant includes heating of heating-system water in hot-water boiler and directing said water to consumers; leakage of heating-system water is compensated by make-up water; to said end, starting water and heating agent are fed to deaerator; deaerated make-up water is directed to heating-system pipe line and is used as heating agent for vacuum deaerator. Deaerated make-up water (before supply to heating-system pipe line and vacuum deaerator) and strating water (before supply to vacuum deaerator) are heated in succession by waste gases of hot-water boiler; deaerated make-up water is heated first. EFFECT: enhanced economical efficiency. 1 dwg
