1. A system for providing the efficient turndown of high flow bottom ash from a hopper, the system comprising:
a. a bottom gate having a single fixed opening for bottom ash to move therethrough;
b. a crusher subassembly including a side discharge crusher and offset conduit, the side discharge crusher receiving bottom ash from the bottom gate and pumping the bottom ash through the offset conduit; and
c. a conveyor subassembly for receiving the bottom ash from the offset conduit and transporting the bottom ash away from the hopper subassembly, the conveyor further including a drive motor providing a drive motor amperage signal;
d. 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.
