ABSTRACT:
The invention provides a method and apparatus for creating a stable combustion flame from natural gas and an oxygen containing gas which is useful for the pyrometallurgical treatment of finely divided materials such as metal ores. In particular, natural gas and the oxygen containing gas are injected in a manner which forms recirculation zones between the natural gas and oxygen containing gas thereby maintaining the stability of the combustion flame. The apparatus of the invention encourages the formation of the recirculation zones by using a bluff body orifice plate to provide a dead space between the injections of the oxygen containing gas and natural gas. Additional gas injection is used downstream in the combustor to create turbulence and further stabilize the combustion flame.
