Abstract
A powdered coal air suspension is charged from a rotating drum via a switch means into a vertical channel which is sealed off from a powdered coal collector in the valve piston by an axially hollow slider. Downward movement of the slider allows the powdered coal to charge into the valve piston while an air valve within the vertical channel opens when the valve piston opens to create an air blast for expelling the coal and air into the combustion chamber.
