THERMAL POWER STATION Russian patent published in 2011 - IPC F01K17/02 

FIELD: power industry.

SUBSTANCE: thermal power station includes steam boiler connected via live steam pipeline to turbine the condenser of which is connected via the main turbine condensate pipeline to feed water deaerator, low pressure heaters connected to the main condensate pipeline, connected to steam regenerative bleeding offs, lower and upper network heaters connected to regenerative steam bleeding offs, lower and upper network heaters connected to delivery water pipeline, connected to lower and upper heating bleeding offs of turbine steam; vacuum make-up water deaerator of heating network, which is connected to water treatment plant of heating network; primary water pipeline is connected to water treatment plant of heating network; surface cooler connected as to cooling medium to primary water pipeline before water treatment plant of heating network is connected to the main condensate pipeline of turbine between the second and the third low pressure heaters in condensate flow direction.

EFFECT: invention allows improving reliability and economy of thermal power station owing to additional generation of electric power on heat consumption at provision of technologically required heating of primary water for preparation of make-up water before water treatment plant and vacuum make-up water deaerator of heating network.
