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

FIELD: peak-load hot-water boiler plants; heat-power engineering. SUBSTANCE: peak-load hot water boiler plant includes hot-water boiler connected to heating-system pipe line, make-up water vacuum deaerator with pipe lines of starting water, heating agent and deaerated water. Deaerated make-up water pipe line is connected to heating-system pipe line through first (in way of flow of waste gases) surface heat exchanger located in gas duct of hot-water boiler; starting water pipe line is connected to vacuum deaerator through second (in way of flow of waste gases) surface heat exchanger located in the same gas duct; heating agent pipe line of vacuum deaerator is connected to deaerated make-up water pipe line after first surface heat exchanger. EFFECT: enhanced economical efficiency. 1 dwg
