Ash Conditioners
Ash conditioners are also called ash unloaders, which are keys to the ash handling system. Ash conditioners are a highly effective pre-treatment system, helping to reduce the amount of ash released into the air prior to final disposal. Ash conditioners mix water with ash uniformly and discharge the ash into a pan.
As the mixture slowly rotates fixed scraper 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.
