FIELD: power engineering.SUBSTANCE: thermal power station containing the condenser of the steam turbine, decarbonator with spray burners and with air duct, which comprises air heater and fan, recycling water system, including fan cooling tower, wet well, gravity conduit, circulating pump, pressure piping to the condenser of the steam turbine and rundown pressure piping to the fan cooling tower consisting of exhaust tower and water collection basin, connected by gravity bypass with the wet well. The exhaust tower of the fan cooling tower is fitted a water distribution tray with spraying nozzles, sprinkling device and water catcher, the spray nozzle of the fan cooling tower is designed as a module of layers of polymeric cellular pipes, the pipes are made cylindrical and placed in all layers parallel each other and are welded on butts of the module to each other in places of contact, meanwhile cavities of all pipes and annular space are filled with hollow polymeric spheres, and the diameter of spheres is 5-10% greater than the maximum size of the pipe mesh.EFFECT: invention allows to increase profitability of thermal electrical station.4 cl, 6 dwg |
