| titleOfInvention | Removing gases from feed water in steam plants |
| abstract | 726,418. Feedwater supply systems. SULZER FRERES SOC. ANON. Dec. 7, 1953 [Dec. 18, 1952], No. 34013/53. Class 123 (2). In a feedwater supply system, harmful salts and dissolved or occluded gases, especially free oxygen, are removed from the make-up water by passing it through an ion-exchange purifying plant 1 and then through heat exchangers 2 and 3 into the main condenser 5 where degassing occurs due to the reduction in pressure. The heat exchangers 2 and 3 are supplied respectively with exhaust and interstage steam from turbine 4 and serve to preheat the makeup water, which has been cooled to a low temperature by the reaction occurring in plant 1, so that a substantially complete removal of gases can take place in the condenser. In a modification, the heat exchanger 2 is replaced by one in which the incoming impure make-up is brought into indirect heat-exchange contact with the colder water emerging from the purifying plant. |
