FIELD: power engineering. ^ SUBSTANCE: circulating water system of power plant with a cooling tower consists of a gravity water pipeline to circulation pump, a recirculation pipeline that connects a pressure pipeline to condenser of steam turbine with drain pressure pipeline to cooling tower which consists of a stack and water-collecting reservoir that in its turn is connected by a gravity bypass channel to water-receiving well. At that stack is provided with water-distributing tray with spray nozzles, sprinkling device, and water collector. In addition circulating water system of power plant with cooling tower is equipped with flow control of circulation water supplied to steam turbine condenser. Circulation water flow control is connected to condenser pressure sensor and to control element installed on pressure pipeline to steam turbine condenser, and with flow control of circulation water through recirculation pipeline. At that flow control is connected to flow sensor and circulation water temperature sensor at condenser inlet, and to control element installed on recirculation pipeline. ^ EFFECT: improving thermal effectiveness of circulating water system, and economy of power plant. ^ 1 dwg |
