transports it using a series of bottom-carry, submerged drag chain conveyors. Both the bottom carry chain and flights and the return chain and flights are contained in a small cross-section, water-tight enclosure. The hopper remains water-impounded to quench the bottom ash and support a water seal at the bottom end of the furnace for optimal

The conveyor forms a circuit where the product can enter and exit through multiple chutes. When the drag chain conveyor is in motion, the discs drag material through the circuit, which is driven by a sprocket at one end. More sprockets can be added to the circuit to provide frictionless direction changes and reduce the system load.

A conveyor belt moves at a fixed rate. One can estimate the volume conveyed over a period of time if the unit carrying capacity is provided. The formula for the Conveyor Volume Output is: CUO = n/m 2 ⋅ W ⋅ TS ⋅ RT. where: CUO = Conveyor Units Output. n = Number of Units carried on a square meter of conveyor area. W = Width of conveyor.
