Abstract

738,286. Steam turbines. BABCOCK & WILCOX, Ltd. Aug. 24, 1953 [Aug. 25, 1952], No. 21290/52. Class 110 (3). [Also in Group XIII] A steam power plant comprises a steam generator which has a high-pressure section 10 and a low-pressure section 13, the sections being located one above the other in a vertical duct 4 and being heated by a downward flow of combustion gases from an oil-fired combustion chamber 2, the gases first passing through a gas turbine 3 which drives a compressor 1 supplying air to the oil burners. The high- and low-pressure boilers consist respectively of inclined steam-generating tube banks 10, 13 which extend between drums 11, 8 and 14, 9. The high-pressure steam from drum 8 passes through a superheater 6 to the high-pressure stage of a steam turbine 28 driving an electric generator 31 whilst the low-pressure steam from drum 9 passes via a superheater 7 to the low-pressure stage of the turbine. Exhaust steam from the turbine is led to a condenser 30, the condensate being returned to each boiler section via economisers 21, 22 by a feed water pump 26. The turbine shaft speed is kept constant over the load range thereof by a governor valve 32 in the high-pressure steam supply line, the pressure at the outlet from superheater 6 being maintained at a constant value by a control 33 which adjusts the firing rate in combustion chamber 2. To prevent the combustion gas temperature at the outlet from duct 4 from falling below the dewpoint whilst maintaining it at an economical low value, a temperatureresponsive element 23 is located in the duct outlet and controls a throttle valve 34 in the outlet line from the low-pressure superheater 7. If for example a change in firing rate causes the gas temperature at 23 to rise, valve 34 is opened, the pressure in boiler section 13 falls and the gases give off more heat to this section, the temperature at 23 thus being restored to the desired value.
