Abstract:
A PLURALITY OF AT LEAST SUBSTANTIALLY PARALLEL CONTROL RODS ARE EACH SHIFTABLE A PREDETERMINED MAXIMUM DISTANCE IN OPPOSITE DIRECTIONS BETWEEN END POSITIONS IN WHICH EACH ROD CLOSES AND FULLY OPENS, RESPECTIVELY, AN AIR ADMISSION PORT COMMUNICATING WITH ONE OF THE COMBUSTION ZONES OF THE GRATE. A LINKING MEMBER EXTENDS TRANSVERSELY TO THE AFOREMENTIONED DIRECTIONS AND IS CONNECTED WITH THE CONTROL RODS. SHIFTING MEANS EFFECTS SHIFTING OF THE LINKING MEMBER IN THE AFOREMENTIONED DIRECTIONS IN A SENSE EFFECTING SHIFTING OF THE RESPECTIVE CONTROL RODS THROUGH DIFFERENT DISTANCES BETWEEN THEIR END POSITIONS.
Abstract:
A slag removal mechanism for fire boxes or the like is comprised of a fluid-containing slag receptacle into which a slagdispensing chute extends through which the slag is deposited in the receptacle. A reciprocable pusher member is disposed in the slag receptacle and extending into the fluid for pushing the slag through the fluid towards the receptacle opening. The open end of the slag-dispensing chute extends into the fluid in the slag receptacle and a sealing arrangement is provided between the open end of the chute and the reciprocating pusher member to prevent admixture of the contaminated fluid portion in which the slag is suspended with the clean fluid portion rearwardly of the pusher member to thereby prevent entrance of dirt into the pusher mechanism.
