Abstract
A furnace burner for combusting solid particulate fuel comprises a drum configured for containing the solid particulate fuel for combustion. The drum is supported in a burn chamber of a furnace for rotation about a substantially horizontal axis. The drum comprises a combustion portion inside the burn chamber and configured to support combustion of the fuel therein and a drive portion connected to the combustion portion and extending therefrom to an external end disposed outside the burn chamber for operative coupling to a drive system to rotate the drum. The combustion portion is perforated to permit passage of air but not fuel through a peripheral wall of the combustion portion, and comprises one or more interior flights extending axially and angularly of the drum in a manner conducive of movement of the particulate fuel, upon rotation of the drum, towards a downstream end to release fuel consumed during combustion.
