FIELD: heat power engineering.
SUBSTANCE: in periods of reduced load on thermal power station, increased extraction of steam from turbine extractions is done. Said steam is used to heat reserve high-temperature heat carrier to 250-300°C, and at peak hours, flow of return heating water is divided into two parallel flows, first of which including 10-30% of return heating water is heated to temperature of 250-300°C at pressure of 4.0-8.6 and then is mixed with second flow and delivered by injector-mixer into turbine system heaters. Used as active liquids in injector is return heating water of first flow, and as passive liquid, water of second flow. Invention provides reduction of consumption characteristics of transfer pumps, reduction of overall dimensions of heat exchange equipment and capital outlays for construction of power stations.
EFFECT: increased efficiency and maneuverability of stations.
