The design and operation of boilers using rice waste present a number of challenges. The overall capacity and efficiency of the boiler are strongly dependent on the fuel, and the supplier has to be able to guarantee the capacity and efficiency within the whole range of the fuel mixture being burned. It is well known that the exit gas composition is strongly dependent on the fuel. Bed temperature, fuel density and particle size significantly affect the hydrodynamic properties of a fluidized bed combustor. The effect of bed temperature, fuel density, particle size on exit gas composition and other hydrodynamic parameters of 10 MW power plant is discussed in this paper, and a heat balance sheet for the 10 MW fluidized bed boiler based on rice waste is prepared. Heat release in the fluidized bed region is also calculated and the efficiency of fluidized bed boiler is found.
