  • Combined primary and spare submerged scraper conveyor arrangement
    Patent number: 4545305
    Abstract: An ash disposal system for a furnace (10) including a pair of submerged scraper conveyors (24, 26) mounted within a common water-filled tank (16) with a water seal (18, 28) between the tank and furnace. The tank is mounted on wheels (32) and has a divider wall (30) between the two conveyors so that the tank can be positioned such that one or the other, or both conveyors together, can be operated to remove ash from the tank. A door or gate (34) in one of the side walls of the tank permits the tank to be completely removed from beneath the furnace when desired.
