Abstract
230,479. British Thomson-Houston Co., Ltd., (Assignees of Richardson, E. L.). March 6, 1924, [Convention date]. Feed-water, heating. - The supply of lowpressure steam from a source other than the main turbine, for heating feed-water in a heater 12 is controlled according to the pressure of this steam and the temperature of the water leaving the heater. In the example, the supply of steam from the main 2 to the auxiliary turbine 17 is regulated by electrically controlled valve means 21. The exhaust from this turbine passes to the heater 12 to heat condensate, from the main turbine 1 and condenser 4, which passes by way of the conduit 11 from a heater 9 supplied with steam from a low-pressure stage of the turbine 1. Electrical contacts 29, 34 and 30, 35 are connected so that each pair is in series. A pressure responsive device 32 with bridge-contact 31 is in communication with the exhaust steam pipe 16 and a thermostat 38 with bridgecontact 36 is connected to the outflow 13 from the heater 12. When both pressure of steam and temperature of water rise or fall current passes to actuate the valve device 21 to diminish or augment the supply of steam to the turbine 17 and hence to the heater 12.
