Abstract

199,991. Aktiebolaget Ljungstr÷ms Angturbin. June 30, 1922, [Convention date]. Feed-water, heating.-In a steam-boiler plant, the exhaust steam from the motor driving the rotary regenerative air-preheater is used to heat the boiler feed-water. The exhaust from a turbine 10 rotating the air-preheater 20 heats the boiler feed-water in a heater 13 placed on the pressure side of the feed-pump. Condensate and uncondensecl steam are taken from the heater through a pipe 16 to a second feed heater 17 placed on the suction side of the feed-pump. The heater 17 is supplied with exhaust steam from other auxiliary machinery. The exhaust from the turbine 10 may be led, wholly or partly, into the heater 17. Steam from an intermediate stage of the turbine may be led into the heater 13 and the exhaust led into the heater 17.
