Combined gas turbine and steam power plant having a fluidized bed furnace for generating electrical energy

Combined gas turbine and steam power plant for generating electrical energy, comprising:

• a combustion chamber for the complete combustion of solid fuels with the aid of a circulating fluidized bed, which serves for generating steam for the steam power plant, said combustion chamber having an upper end region and a lower end region;
• a circulation conduit disposed outside said combustion chamber and connected between said upper end region and said lower end region of said combustion chamber for circulating said fluidized bed, a feeding point connected to said circulation conduit for feeding a portion of the fuel into said circulation conduit, said circulation conduit having a fuel degasification and gasification zone formed therein in the vicinity of said feeding point;
• a removal point disposed along said circulation conduit for removing combustible gas from said circulation conduit, said removal point being disposed in said fuel degasification and gasification zone;
• and
• a combustor of the gas turbine plant in which air required for operation of the gas turbine plant is heated by combustion of said combustible gas, and a combustible gas line connected between said removal point and said combustor.
