This patent describes an improvement in an apparatus for combustion of sulfur-containing particulate carbonaceous fuel. Oxidizer gas and particulate fuel are introduced into a substantially cylindrical primary combustion chamber. The input velocities, mass-flow rates and combustion temperatures are regulated to minimize the concentration of volatilized and liquid slag in the output gaseous products of combustion. The walls of the combustion chamber are maintained within a temperature range such that a layer of solidified slag is retained on the inside surfaces of the walls.
