Abstract

709,888. Steam-raising in boilers. KONINKLIJKE MACHINEFABRIEK GEB. STORK & CO. N.V. Oct. 6, 1952 [Jan. 5, 1952], No. 24997/52. Classes 123(2) and 123(3) In a steam plant comprising a boiler 1 with superheater 2 supplying steam, to a twostage turbine 3, 4, during starting up the superheated steam is directed by a conduit 20 to a closed storage tank 22 and also, if desired, to a degassing condensate tank 13 in the boiler feedwater supply system. The latter system comprises a condenser 7, to which the exhaust steam from the turbine is led, and associated pump 8 which delivers the condensate through preheaters 9, 10 to the tank 13 and also, when required, through a conduit 28 to the tank 22, a further conduit with the normal feedwater pump 14 being connected between said tank 13 and' the boiler economizer 17. The condensate supply conduit 28 to the tank 22 is fitted with a valve 29 controlled by the water level in the tank, and the two tanks 13, 22 are connected by a conduit 27 with pump 26. Before firing-up the boiler a valve 33 in the superheater outlet pipe 20 is opened to permit steam to flow to the tank 22; simultaneously a circulating pump 23 in a conduit 24, leading from the bottom of the tank 22 to a sprinkler 25 at the top thereof and provided with a valve 30 controlled by the steam pressure in the said tank, is started, the pump 23 being stopped and the valve 33 closed at the completion of firing-up. During operation of the plant, the water in the tank 13 is maintained at the desired temperature by steam bled from the turbine, through conduits 19, 34, and the steam pressure in the tank 22 is maintained by an automatically-operated valve 31.
