FIELD: circulating water supply systems of industrial-enterprise power installations. SUBSTANCE: steam-ejector plant has evaporator communicating with steam ejector, feed and service tanks, condenser, and water treatment device. Evaporator accommodates distributing header communicating with feed tank. Steam ejector communicates with multiple-effect vacuum evaporator. Evaporator communicates with steam ejector and service tank 4 through water treatment device 6. The latter is installed between feed and service tanks. Its housing is divided by means of partitions into intercommunicating filtering, cation- and anion- exchange zones. Service tank, water treatment device, feed tank, and evaporator are disposed at upgrading levels. Proposed plant provides for simultaneous cooling and purification of circulating water in power units and for circulating condensate makeup. EFFECT: reduced extra charges for treatment of water used at cogeneration stations for steam generation. 1 dwg
