Abstract
An improved grate and method for burning solid fuel having a support for the fuel, a fan, a multiplicity of preheated air jets uniformly distributed across the entire area of the grate and directed through the support generally upwardly into the lower burning surface of the solid fuel, and a trough for collecting a layer of glowing coals located immediately below the jets and in close proximity to the burning lower surface of the solid fuel. The grate provides the cleanest burning and lowest fuel consumption occurs when only one layer of solid fuel is placed on the grate.
