Robb, M F

A coal burning apparatus actuated by a stoker of the underfeed type includes a burner body formed of a plurality of vertically stacked rings with spaces between the rings extending horizontally to form a tuyere. A tuyere is easily made by stacking rings onto a burner base in a surrounding relationship to the stoker throat. A rotating ash ring is mounted to the exterior of the tuyere for disposing ashes outwardly beyond the periphery of the burner so that they may fall into a provided ash box. The burner air for sustaining combustion is provided to the interior of the tuyere from one of a pair of provided ports in the burner base. The alternative location of the air ports permit the air duct for providing combustion air to be extended from either end of the burner assembly.
