ABSTRACT:
Removal of molten slag from combustion chambers for combustion of combustible gases containing entrained slag-forming particulates, is frequently a problem since the slag tends to solidify in the tap-hole resulting in bridging and eventual pluggage of the tap-hole. This invention eliminates this problem by providing a dam around the periphery of the tap-hole of sufficient height to maintain a pool of molten slag on the inclined bottom of the combustion chamber to a depth whereby said slag pool is an effective heat sink to maintain the molten slag in flowable condition, and by providing in the dam at least one inclined drain trough which over-hangs the tap-hole a sufficient distance to minimize contact of draining slag with the walls of the tap-hole.
