ABSTRACT:
A pressurized internal circulating fluidized-bed boiler is incorporated in a combined-cycle electric generating system in which a fuel such as coal, petro coke or the like is combusted in a pressurized fluidized bed and an exhaust gas produced by the combusted fuel is introduced into a gas turbine. The pressurized internal circulating fluidized-bed boiler includes a pressure vessel, a combustor disposed in the pressure vessel and a primary fluidized bed incinerating chamber provided with an air diffusion device. A thermal energy recovery chamber is partitioned from the primary fluidized bed incinerating chamber by an inclined partition wall. A fluidizing medium flows into and out of the primary incinerating chamber and the thermal energy recovery chamber.
