ABSTRACT:
This invention concerns the burning of fuels, such as natural gas, at high temperatures. The invention includes a high-efficiency burner which achieves substantially complete combusiton at modest cost. The burner of the present invention includes a generally cylindrical housing having a central bore and two concentric annular regions. A lance is inserted through the central bore, and protrudes slightly from the front face of the burner housing. The fuel is directed through the inner annular region, and oxygen-enriched combustion air is directed through the outer annular region. Substantially pure oxygen is directed through the lance. The gases in the lance and the annular regions do not communicate with each other within the burner housing, and all burnign takes place outside the housing. The same supply of oxygen can be used to supply the lance and to enrich the combustion air. The present invention achieves overall results which are substantially comparable to the results obtained from pure oxygen burners, but at a greatly reduced equipment cost, and with reduced operating cost.
