Steam power plant with hermetic turbogenerator and with the closed cycle of working medium and method for cooling the electric power generator in the steam power plant with hermetic turbogenerator and with the closed cycle of working medium

摘要

steam power plant is characterised by having an additional heat exchanger (7) connected to the steam turbine (2) and of the electric generator (1) so that a pair of exit (6) of the steam turbine (2) against the influence of the space electric generator (1) flows through an additional the heat exchanger (7),where is ochu0142adzana by factor working or external coolant stream (11). an additional heat exchanger (7) is connected with a pump (10) and wymiennikiem - wytwornicu0105 pairs (4) so that the working factor originating from the pump (10) flows through the additional heat exchanger (7) and a cooling nozzle (6) of the turbine (2).in another variation of the plant an additional heat exchanger (7), is connected with the outer stream of coolant (11), which couple the exit (6) of the steam turbine (2) is ochu0142adzana.in another variation of the power plant for the additional heat exchanger (7) has a divider which is connected with the condenser (8) and the second additional heat exchanger and electric generator (1) so that a part of the vapour stream exit (6) flows to the electric generator (1) by a second additional heat exchangerand the remainder of the stream is passed to a condenser (8), whereby the second additional heat exchanger is connected outside the stream of coolant (11).cooling way is characterized by the fact that a nozzle (6) of the steam turbine (2) has an additional heat exchanger (7), where it cools and then headed to space electric generator (1) for cooling.the working factor originating from the pump (10) is heading for a heat exchanger and the steam generator (4), by means of an additional heat exchanger (7), the cooling steam exit (6) of the turbine (2), while energy produced from steam heated him exit (6).in another variation of the additional heat exchanger (7) makes the external stream of coolant (11), which cools the steam outlet (6) of the steam turbine (2).
