ABSTRACT:
An improvement for use in a coal stoker is disclosed. The improvement device is used with a common stoker generally including a hopper operatively connected to and aligned with a base box forming an ash pit. The base box, through its sides sloping downward from the hopper, supports a ramp. The lower part of the ramp is a perforated fire grate while the upper section is a plate that extends through the hopper bottom. A fan effecting a forced draft through the grate is operatively connected to a motor. The improvement comprises a linear reciprocation action carpet that overlies generally the length and width of the plate. The carpet's movement is effected by its connection to the motor. When coal is fed into the hopper and the movable carpet is activated by the motor, the carpet will move in a linear reciprocating direction. The coal falling on the carpet from the hopper will continually advance in an even flow from the carpet's leading edge onto the perforated grate.
