Abstract
A system and mechanism for bottom ash flow turndown from a hopper, through a crusher, and to a conveyor, the system including a fixed flow restrictor and a variable speed side discharge crusher to modulate bottom ash flow in the absence of gate or valve flow from a hopper, the conveyor providing a signal corresponding to an overfeed condition to enable a controller to operate the crusher and/or the conveyor to eliminate overfeed conditions.
Claims4
A system for providing the efficient turndown of high flow bottom ash comprising fine and large ash particles from a hopper, the system comprising:
- a. a crusher subassembly;
- and
- b. a conveyor subassembly for receiving the bottom ash from the crusher subassembly and transporting the bottom ash away from the hopper the conveyor further including a drive motor providing a drive motor amperage signal;
- c. a controller connected to the conveyor and the crusher, the controller increasing the speed of the drive motor and selectively turning the crusher on and off in response to a drive motor amperage signal corresponding to an overfeed condition.
