Abstract

An apparatus for the continuous gasification of coal by partial combustion with a reactant gas is disclosed, wherein a vertical gasification reactor is provided with a reactant supply and ash removal assembly adapted to supply coal and reactant gases and to remove ash particles to and from the reactor via a constricted passageway in the reactor bottom. The assembly includes an ash quench chamber having means for supplying coal and reactant gases through the reactor disposed therein which opens opposite the constricted passageway a predetermined distance therefrom. The apparatus may be operated continuously without collecting by-product ash particles in the reactor and without superheating the reactant supply means.
