Abstract
755,164. Critical-pressure steam boilers. SULZER FRERES SOC. ANON. July 23, 1954 [July 25, 1953], No. 21641/54. Class 123(2). In a critical-pressure steam boiler, water is delivered by a feed pump to an inlet header 2 and is distributed between a number of parallel tubes 3 which pass separately through a preheating zone 4, conversion zone 5 and primary superheating zone 6 to a collecting header 7 from which the steam is led through parallel tubes of a secondary superheater 8 to points of consumption. A pressure release valve 9 is fitted in each tube 3 after the conversion zone so that a temporary reduction in pressure to below the critical pressure may be effected in a tube, the wet steam so produced serving to wash out any salts deposited in the said tube, and, in order to reduce the consequential backflow of steam from the collecting heater 7, a throttling device, such as a nozzle 11 which permits freer flow of steam in the forward direction than in the reverse direction, is provided between each valve 9 and collecting header 7. The nozzle 11 may be replaced by a long length of tube or a non -return valve.
