1495877 Steam and gas turbine power plant BBC BROWN BOVERI & CO Ltd 12 May 1976 [14 May 1975] 19534/76 Headings F1G and F1Q The invention relates to a combined gas turbine plant 1 and steam turbine plant 2 having at least one associated combustible gas producer, 5 and 6. The gas turbine plant comprises a compressor 7, combustion chamber 9 and turbine 11, the turbine driving the compressor 7 and an electric generator 12, the combustion chamber being supplied through line 10 with gaseous fuel produced in the gas producer 5, and the exhaust gases from the turbine passing to the furnace of a steam generator 14. Gaseous fuel from the gas producer 6 is passed to the furnace of the steam generator through line 15. Steam generated in the steam generator is passed to steam turbine 16 which drives an electric generator 19, the exhaust steam being condensed at 17 and returned to the steam generator. A portion of the air delivered by the compressor 7 is taken off through line 20 and further compressed in compressor 21 being then discharged through line 22 to the gas producer 5 to which coal is supplied at 23. The combustible gas from the producer passes through line 24 to a turbine 25 which drives the compressor 21, the gas then passing through line 10 to the combustion chamber 9. The second gas producer 6 is supplied with air under pressure through line 28 and with coal through inlet 26, the air being supplied by compressor 27 which draws in ambient air. The gas from the producer discharges through line 29 to a turbine 30 which drives the compressor 27, the gas then discharging through line 15 to the furnace of the steam generator. The gas producers 5 and 6 may be connected in parallel as indicated by lines 31, 32. |
