Abstract

1,168,043. Forced flow steam generators. SULZER BROS. Ltd. 23 May, 1968 [23 May, 1967], No. 24645/68. Heading F4A. [Also in Division F1] In a forced flow steam generator, working medium is drawn off down-stream of a heating surface 20 and returned upstream of the surface through the tubular nozzle 8 of an ejector 6 by feedwater entering ejector chamber 7 and the nozzle 8 is axially adjustable in dependence on the steam generator load to vary the crosssection for feedwater flow. The nozzle 8 is adjustable by a servomotor 16 with a pinion 15 engaging teeth 14 on nozzle rod 13. A control unit 51 receiving signals from a flow rate measuring element 50 downstream of a mixing tube 11 and a diffuser 12 and a load controller is connected to the servomotor 16. The speed of a feed pump 2 supplying water from a tank 1 to an economizer 5 and the ejector 6 is controlled by a unit 41 receiving signals from a feedwater flow measuring element 40, an element 42 indicating the water level in the separator 21 downstream of the evaporator heating surface and a steam flow measuring element 45. The level measuring element 42 also controls a valve 31 in a line leading from the separator 21 to the feedwater tank 1 via a feedwater cooler 4. Steam-heated preheaters 4, 28 and 29 are provided for the feedwater downstream of the feed pump 2 and upstream of the feedwater tank 1, respectively. Steam from a superheater surface 22 is supplied to a turbine 24 exhausting to a condenser 26. The servomotor control unit 51 may receive a signal solely from the load control apparatus. The signal from the element 42 may control the servomotor 16 and that from the element 50 may control the feed pump 2. In a further embodiment, Fig. 2 (not shown), the flow of feedwater is controlled by a valve (2<SP>1</SP>) and a load control governor (65) adjusts the amount of air and fuel supplied to the burner (66). Water recirculating from the separator (21) is cooled by feedwater passing through a tubular cooler (80).
