The Bureau of Mines designed, constructed, and operated an 18-in- diam fluidized-bed combustor for highly caking coals to evaluate the method for possible application to power generation. In initial tests, combustion was carried on successfully, with carbon losses as low as 0.8 percent. Coal ash was not satisfactory as a bed material, but mullite proved to be acceptable. Overall heat- transfer coefficients from the bed (-20 +50 mesh mullite) to a water- cooled tube were about 75 btu per hr-sq ft-deg. F.
