1. Apparatus for uniformly wetting and discharging ash, comprising a cylindrical, open top pan, sloped at an angle of about 55°
- degrees with respect to a floor, a mesh covering the floor of said pan, a motor for rotating said pan about 5 to 6 r.p.m., an ash charge chute discharging ash into the lowermost portion of said pan, fixed scraper means of abrasive resistant refractory blocks including an end scraper disposed angularly at an obtuse angle and extending at right angles to the surface of said mesh on the bottom of said pan and occupying a portion of the surface of said pan, means for adjusting the height of said refractory blocks, means for adjusting said blocks laterally, water spraying means for spraying water onto the surface of said discharged ash as it is being scraped in said pan, whereby said rotated ash will be effectively tumbled back to the bottom of said pan by said scraper means to enable uniform wetting of practically all the particles of tumbled ash as it is discharged downwardly from the top of the side of said pan, and a dust hood totally enclosing said pan having an open bottom for discharging conditioned ash.

Abstract
Apparatus for uniformly wetting and discharging ash. It is enclosed in a dust hood. It comprises an open top pan disposed at an angle of about 55° degrees with respect to a floor, rotated at slow speed. An ash charge chute discharges ash into the pan. Fixed scraper means extend at right angles to the pan to scrape the bottom of the pan while water is sprayed onto the surface of the discharged ash so that the rotated ash is tumbled back to the bottom of the pan to effect uniform wetting of the tumbled particles as they are discharged downwardly from the top of the side of the pan.
