Abstract
An incinerator for pasty or sludge-like wastes includes a fixed hearth within its combustion chamber defining a surface for the burning thereon of a layer of the waste material. The surface of the hearth is sloped downwards toward an ash receiving region to provide for movement of the burning waste materials which are introduced through waste inlet ports. The hearth has a downward slope which progressively increases towards said ash receiving region thereby to compensate for the gradually increasing consistency of the burning materials and thus provide for their continued movement over the hearth surface under the influence of the gravitational forces thereon. The furnace also includes means for providing a rotating flow of burning gases and combustion air within the chamber thereby to ignite and support the combustion of the sludge on the hearth surface.
