ABSTRACT:
A fluidized bed combustion device adapted for use with a boiler has an air distributor consisting of a plurality of rows of generally horizontally oriented, apertured sparge pipes disposed in a bed of inert particulate material. The rows of pipes are vertically spaced apart with the upper row being connected to a start-up burner for receiving heated combustion products and excess air and the lower rows of pipes are connected to selectively receive air or inert gases through a separate delivery path. During start-up and low load conditions, only the upper row of pipes is pressurized and so that only the upper portion of the bed is fluidized to minimize the heat input requirements. Once the upper portion of the bed has been heated to the required temperature, primary fuel is delivered to sustain combustion without the start-up burner. At the completion of the start-up process and during high fire conditions all of the rows of tubes are pressurized to provide a deeper bed of fluidized material.
