ABSTRACT:
Apparatus for burning material such as fuel, waste material and the like, which when burned produces gases within which pollutants are entrained and for cleaning the gases. The apparatus comprises at least two combustion chambers, comprising an upper chamber and a lower chamber, the chambers being in vertical and lateral stepped adjacency; the lower chamber comprising a grate upon which material is to be burned disposed at a predetermined level; the upper chamber comprising a grate upon which material is to be burned, disposed at a level above the lower chamber grate. Fluid communication is provided between the chambers located above the lower chamber grate and below the upper chamber grate; fluid communication is also provided between the chambers above the upper chamber grate; the gases produced by the material burning on the lower chamber grate are directed through the fluid communication areas to below and above the upper chamber grate; the gases below the upper chamber grate are directed up through the upper chamber grate and through the burning material thereon; the chambers, the fluid communication areas and the exhaust constitute a flue for passing the gases produced by the burning material in both chambers. The grates are of the conveyor type and move the burned and burning material from the upper chamber to the grate in the lower chamber and from the lower chamber to a next adjacent lower chamber to a dumping and carting area.
