Abstract
A stationary, stepped, downwardly inclined incinerator grate assembly includes independent combustion control at each step through the provision of laterally disposed, perforated support tubes each joined to an inclined grate plate, likewise having openings therethrough. Valve devices associated with each support tube allow control of the volume of a mix gas which impinges upon a deposit of a feed material on the grate plates while damper elements in plenum chambers communicating with the apertured grate plates are controllable to regulate the admission of combustion air to the feed material.
