ABSTRACT:
A slag flushing and water level control system for the burn tank of a metal cutting apparatus utilizes a pair of separate water displacement chambers disposed in the tank below an inclined slag-collecting intermediate floor section. Water is displaced from one chamber by compressed air and caused to flow over the upper edge of the inclined floor and cascade downwardly thereover, carrying with it the slag deposited thereon. The water used in flushing the floor is collected in the second displacement chamber and subsequently displaced therefrom by air pressure to fill the burn tank and raise the level therein to a selected operating level. After completion of the cutting operation, sequential relief of the air pressure in the first and second chambers allows appropriate volumes of water to return thereto for a subsequent cycle.
