Abstract

1,061,889. Forced flow steam boilers. SULZER BROS. Ltd. July 6, 1964 [July 23, 1963], No. 27817/64. Heading F4A. In a steam power plant comprising a forced flow boiler supplying a turbine having a high pressure stage 9 and a low pressure stage 15 with an intermediate stage reheater 5, the boiler plant is started by first pumping water from a feed tank 19 through an economizer 2, an evaporator 3, a superheater 4 and a separator 21 to return to the feed tank 19 through the valve 41. The boiler is fired at 10% of full load rate and the steam that evolves in the separator as pressure reduces through the valve 20 flows through the pipe 42 to the reheater 5 and then to the high pressure turbine 9 via pipe 25, cooling the reheater and warming the high pressure turbine 9, the steam exhausting from the high pressure turbine 9 into the feed tank 19 to de-aerate water entering the tank from the condenser 16. The valve 14 is then opened to warm the low pressure turbine 15 and when the high and low pressure section are adequately warmed the turbine is run-up to speed with the firing still at 10% full load rate. As the steam temperature rises the steam from the superheater 4 is fed directly to the high pressure turbine 9 via pipes 7 and the reheater is fed with expanded steam from the said turbine 9. By reversing the above procedure a rapid shut down time is achieved. In a modification the turbine may be subdivided into three parts with a reheater between the high and medium pressure stages and between the medium and low pressure stages, during starting the latter reheater being connected to the entry to the high pressure or to the medium pressure stage.
