Abstract
The invention is a dry ash handling system that allows ash to fall into a refractory lined ash car riding on rails in a sealed tunnel. The ash falls through a chute coupled to a negative pressure rotary combustor. Any unburned waste is allowed to continue burning in a burn-out chamber while, after removal from the chute because air is allowed to be pulled through the ash from the bottom by the negative pressure. When burn-out is complete, the ash is sprayed to quench any remaining smoldering embers. After removal from the tunnel, the car is sealed with a lid and allowed to cool further. During this period, samples can be removed from the car through sample ports. The car is transported to a landfill by a tilt bed truck and a hinged door on the car allows the ash to be dumped.
