Abstract (en)
A process for the partial combustion or oxidation of coal, the process being characterized by recovery of energy value in flyash and concomitant reduction of solids disposal requirements. In particular, the flyash is oxidized in a fluidized bed, preferably with other carbonaceous materials, and the heat recovered is used, e.g., to dry feed coal.
