ABSTRACT:
The gas turbine power plant with a fluidized-bed combustor for the burning of coal comprises a closed circuit or loop cooling system for the fluidized-bed combustor through which is circulated liquid metal. The cooling system includes, in the bed of the fluidized-bed combustor, a first heat exchanger by which the liquid metal absorbs heat from the bed and a second heat exchanger by which heated liquid metal is passed in indirect heat exchange with compressed air to heat the latter, the heated compressed air being mixed with the combustion products discharged from the fluidized-bed combustor at a point upstream from the gas turbines.
