Recently research efforts relating to fluidized bed furnaces under pressure (FBP) has grown up. The basic advantage of such furnaces is in a possibility of the combined cycle realization, when steam, generated in the boiler, is utilized in the steam turbine, and combustion products with the increased pressure are used in the gas turbine. Such a scheme increases the thermodynamic efficiency of the cycle and also allows at a greater extent reducing the overall dimensions of the furnace units and lowering pollutant emissions into atmosphere.
