Particulate waste product combustion system

摘要

The carbon content of the residue from combustion of agricultural waste products is controlled and the fly ash content of the gaseous exhaust minimized by utilizing a portion of the combustion supporting air to enhance fluidization of the waste products above a fixed bed while being agitated by a rotating sweep arm inducing radially outward movement toward a residue collecting zone from which a sweep arm paddle displaces the residue into a discharge duct. The waste product feed is conveyed at a uniform weight flow rate to a central location in the combustion chamber above the bed from which of the feed is dropped onto the bed.
