Abstract
1,154,476. Direct contact steam generators. SIEMENS-SCHUCKERTWERKE A.G. 22 Sept., 1966 [30 Sept., 1965], No. 42425/66. Heading F4A. Water from a condenser 5 is passed by a pump 6 through low pressure feed water heaters 7, 8 to a feed water container 9. A feed pump 10 draws water from container 9, and passes it through high pressure feed water heaters 11, 12 and injects it into return superheated steam from conduit 14, in one or more injection cooling devices connected in series and/or parallel acting as an evaporator 13 whereby saturated steam is produced. This saturated steam is passed by circulating pump 16 through superheater 17 after which part is returned to the evaporator 13 by conduit 14 to generate further saturated steam, whilst the remainder passes through a conduit 20 to high and low pressure turbines 2, 3. Alternatively, saturated steam may be drawn off upstream or downstream of the circulating pump 16 and passed through conduit 22 and separate superheater 23 on its way to the turbines. Superheater 23 may also be used as a finishing superheater after superheater 17. The system is controlled by using fuel controller 28 to vary the heat input to the superheaters in accordance with the live steam pressure measured at point 26, and by controlling the circulating pump 16 through controller 31 in accordance with the temperature of the superheated steam entering the evaporator 13 at point 32 and by controlling the feed water flow through pump 10 through controller 34 in dependence on the steam temperature after the evaporator 13 at the point 35. Additionally the feed water flow determined by pump 10 or a regulating valve (not shown), may be controlled through controller 38 in dependence upon the temperature of the steam entering the superheater at the point 36. The live steam pressure at point 26 may be maintained constant by the action of valve 40 under controller 41. Both the feed supply and the fuel controller may then be varied in response to the load setting on the system.
