FIELD: heat-and-power engineering.SUBSTANCE: invention relates to heat engineering and can be used in devices and operation of thermal power plants. Water-steam circuit (10) includes steam generator (11), steam turbine (12), condenser (13) with water cooling and pump (15) of feed water. Condenser (13) contains body (28) with at least one tube bundle (18) with inner air cooler (21), which is connected with external using vacuum pump (25) by means of line (23) of suction. To reduce time for cleaning of condenser in starting water-steam circuit (10) without using auxiliary steam, additional line (26) leads to drive shutoff valve (27) connects outer ejector vacuum pump (25) with condenser (13).EFFECT: operation of cutoff valve (27) is controlled by device (29) of control.2 cl, 3 dwg |
