Abstract

834,784. Steam and gas-turbine plant. BABCOCK & WILCOX Ltd. June 1, 1956 [June 3, 1955], No. 15962/55. Class 110 (3). [Also in Group XIII] A water-tube boiler forming the steam raising part of a power plant particularly for marine use which comprises a steam turbine 81 and a gas-turbine 82 comprises two identical units 1, 2, each including a first and second section 3, 4. The first section 3 consists of a marine boiler 5 similar to that described in Specification 714,050 while the second section consists of heat exchangers disposed in an upright gasturbine exhaust gas passage 6 separated by a metal partition 47 from the marine boiler. The latter has a tube-lined furnace 7 fired by burners 8, hot combustion gases leaving the furnace through a screen 24 and flowing through parallel passes 14, 15 containing convection generating tube banks 23 and 25, 26, respectively, the pass 14 also containing a superheater 11. The gas flows are proportioned between the passes by adjustment of outlet dampers 21, 22. The passage 6 which receives the exhaust gases from the gas turbine 82 at its lower end contains a superheater 48, an evaporator bank 49 and a steaming economizer 53. The gases from the marine boiler mix with those from the passage 6 in a space 61 and flow upwardly through flues 12, 54 respectively locating an air heater 13 and an economizer 55 to a stack. The steam-water mixture generated in the furnace lining tubes and in the convection heating portions of sections 3, 4 passes into a drum 9 whence steam flows serially through the superheaters 48, 11. During normal operation, with the gas and steam turbines operating at nominal power output, the desired degree of superheat is obtained with the proportioning dampers 21, 22 fully open and the steam temperature at other loadings is maintained constant by adjusting one or other of the dampers. If the gas-turbine is not operated and the firing rate of section 3 is increased to maintain the same steam output to the turbine 81, the superheat temperature does not tend to rise in view of the location of the superheater 48 in the then unheated passage 6.
