Abstract

716,433. Gas turbine plant. POWER JETS (RESEARCH & DEVELOPMENT), Ltd. Aug. 29, 1952 [Sept. 28, 1951], No. 22753/51. Class 110(3) A combined heat and power supply system comprising an air compressor which discharges through a heater to a gas turbine delivering useful power and a steam raising boiler having a combustion chamber to which combustion supporting gas is supplied from the turbine exhaust, the exhaust gases of the boiler being used to supply at least in part the heat required at normal load in the heater, has a by-pass around the turbine and a further combustion chamber supplying additional heat to the heater fed with combustion supporting gas by the turbine arranged so that the steam and power requirements may be varied independently. Air supplied by a compressor 2 is heated in a heater 3 and then expanded in a turbine 4 driving the compressor. The exhaust from the turbine 4 is passed to a boiler 6 where it is used to support'the combustion of fuel fed through the pipe 7. The exhaust gases from the boiler pass through the heater 3 and the feed water heater 8 to atmosphere. Water is supplied to the boiler 6 from a pipe 10 and the resulting steam is used in a turbine 11 which assists the turbine 4 to drive the compressor 1 and generator 14. The exhaust steam is used in a process shown at 12 from which wet steam or water is recovered and returned via a condenser, where necessary, to the feed water heater 8. Make up feed water is supplied by a compressor driven evaporating still comprising a compressor 15, an evaporating chamber 16 and a heating coil 17. The compressor 15 maintains a low pressure in the chamber 16 and if this chamber is first heated, vapour is formed which is drawn off by the compressor. This vapour is further heated and compressed by the compressor 15 and discharged through the coil 17. The work put in by the compressor 15 maintains the operation of the system. The condensate may be led away or passed into the feed pipe 10. If the demand for steam falls when the demand for electricity is maintained, the fuel supply to the burners 7 is reduced and at the same time a combustion chamber in either of the positions 19, 20 is started up. If the demand for power falls, the turbine 4 may be bypassed by opening the valve 22. In a modification, a combustion chamber 24 which may be put into or taken out of operation is placed between the heater 3 and turbine 4. In another modification, the compressor is arranged in two stages with an intercooler between them and the compressor driving turbine is arranged in two stages with a reheater between them. The steam from the boiler may not necessarily be used in a turbine.
