ABSTRACT:
A slag removal system for wet bottom boilers is provided wherein tandem tap holes are provided. The first hole comprises a vertical hole to be selectively closed by damming and the second hole comprises a horizontal hole and is dammed or sealed with sand in order to seal against the passage of boiler gases through the tap holes. In addition, multi-compartment slag tanks are provided and each slag tank may be selectively placed into and taken out of service, as desired. Further, an alternate type of slag tank is disclosed wherein a suitable cooled bed of slag particles is provided on a turntable and the tapped molten slag is deposited onto a peripheral portion of the turntable as the latter is rotated and a breaker is provided for breaking up the resultant ribbon of solidified slag at predetermined intervals.
