Abstract
A calcining kiln for decontaminating and detoxifying materials, such as earth, contaminated by hazardous chemicals and substantially incapable of autogenous combustion, consisting of an elongated kiln body through which the material to be treated is conveyed in the form of a tumbling bed, and apparatus for directing flame jets of high temperature against and into the tumbling bed at closely spaced intervals along the length of the kiln body to stir and agitate the material. The tumbling and the stirring and agitation reduce the material to a pulverized form of fine particle size so that all of the contaminating chemicals may be reached and destroyed by the high temperature flame jets. Various fuel gases may be used depending on the heat producing capacity required under any particular circumstances, and the heat produced in successive longitudinally spaced zones of the kiln body may be independently controlled according to the heat requirements in each zone.
