Abstract
1,076,999. Superheating steam. COMBUSTION ENGINEERING Inc. Sept. 3, 1964 [Sept. 20, 1963], No. 36226/64. Heading F4A. [Also in Division F1] A steam turbine plant comprises in flow series a steam generator 16, main control valve 20 and turbine stages 22, 26, 28, a reheater 24 being disposed between stages 22, 26. The condensate is pumped from a condenser 2 through feedwater heaters 6, 12 and a deaerator 8 back to generator 16. For restarting while the turbine casings are still hot, valve 20 is closed and high temperature and pressure steam from generator 16 flows through branch pipe 32 to the high pressure side of a heat exchanger 34. The steam then passes through a throttle valve 36 and enters a flash tank 38 at reduced pressure, any water collected in tank 38 being returned to condenser 2 through pipe 42. Some of the throttled steam passes through valve 48 to the low pressure side of heat exchanger 34 to be heated by the high pressure steam from pipe 32, the heated steam leaving the heat exchanger through pipe 49 to enter turbine 22. Since this steam is at high temperature the thermal gradients across the turbine casings are reduced. Throttled steam not flowing to heat exchanger 34 flows through pipe 44 to de-aerator 8 or condenser 2. In a modification, Fig. 2 (not shown), the heat exchanger is in the main steam pipe 18. The arrangement of heat exchanger and throttle valve is applicable also to a gas turbine plant.
