Abstract

899,904. Turbine plant. BABCOCK & WILCOX Ltd. April 18, 1961 [April 23, 1960], No. 13932/61. Class 110 (3). In a power plant comprising vapour generating means supplying vapour through a vapour superheater to a vapour turbine, a furnace supplied with combustion air under pressure to provide combustion gases to heat the vapour superheater or the vapour superheater and vapour generator and to operate gas turbine means, has a desuperheater arranged to saturate and partially condense vapour bled from the vapour turbine means and to heat with the heat extracted from the bled vapour combustion air fed to the furnace. A two-stage steam turbine 1 and a gas turbine 2 each drive an electric generator (not shown). The steam turbine comprises a high pressure stage 11 and a low pressure stage 12 fed with steam from a boiler unit 3 having a combustion chamber 4 fired by fuel introduced by burners into the stream of exhaust gases of the gas turbine 2. The hot gases leaving the combustion chamber 4 pass through an outlet 5 into a downpass 6 containing a superheater 7, reheater 8 and economiser 9. Boiler 3 comprises a steam and water drum 14 and steam producing tubes 13 which line the walls of the combustion chamber. The condensate from the condenser 15 is fed by a pump 16 through bled steam feed water heaters 21, 22, 23 to the boiler feed pump 10. The feed water heaters are fed with steam bled from the points 31, 32, 33 after it has passed through the air heaters 31A, 32A, 33A, in which air from the compressor 27 is heated before passing to the combustion chamber 24 into which liquid or gaseous fuel is injected by pump 25. The air heaters may be arranged in series or in parallel. In a modification, Fig. 2 (not shown), a single stage turbine receives steam from a superheater and a boiler forming part of the furnace supplies combustion gases to the gas turbine. The gas turbine exhaust gases may be used to heat an economiser or a low pressure evaporator feeding a low pressure stage of the turbine. In a further modification, Fig. 3 (not shown), the superheater and reheater are arranged in the furnace feeding the combustion chamber. In this arrangement, the air heaters 31A, 32A, 33A are arranged in parallel. The boiler in this case may be heated by a nuclear reactor.
