FIELD: utilization of heat of blow-down water; boiler plants. SUBSTANCE: proposed method includes generation of steam from feed water fed to boiler which is de-aerated in feed water de-aerators where heating agent is delivered; mineral admixtures are removed from boiler together with blow-down water. Blow-down water of steam boilers of higher working pressure is used as heating medium for feed water de-aerator of steam boiler of lower working pressure. EFFECT: enhanced economical efficiency; enhanced ecological safety. 1 dwg
