METHOD OF REGENERATIVE HEATING OF FEED WATER IN JET HEATER Russian patent published in 2001 - IPC

FIELD: jet facilities. SUBSTANCE: proposed method includes delivery of steam into turbogenerator, takeoff of steam from turbogenerator, delivery of steam from turbogenerator and condensate from condenser into jet apparatus with condensing of steam in jet apparatus and heating of condensate with subsequent delivery of heated condensate into deaerator and further on into boiler-steam generator. At starting of jet heater, first pump is connected to mixing chamber of jet apparatus to set, by means of pump, the pressure in mixing chamber lower than that in condenser and then passage for condensate from condenser into jet apparatus is open and pressure in built in mixing chamber, in section between outlet section of nozzle and outlet section of mixing chamber, equal to pressure before pressure rise in mixing chamber. Then steam is delivered into jet apparatus, and pressure equal to pressure before pressure rise in mixing chamber is maintained in mixing chamber in zone after outlet section of nozzle. EFFECT: improved reliability and efficiency of heater jet apparatus. 4 cl, 2 dwg
