ABSTRACT:
A fluidized bed combustion apparatus in which the combustion chamber has a dense fuel bed created in the chamber, and a grinding mill connected to the dense fuel bed portion of the chamber and so operated as to classify the material into fine and coarse particulates with the fines being directed into the bottom of the dense fuel bed and the coarse particulates being directed to the top of the dense fuel bed. The apparatus is placed under the control of a controller which regulates the mill to feed fines and coarse particulates in proportions for maintaining optimum average particle size and hence optimize boiler efficiency.
