摘要： A method of heating a charge material by controlling heat flux in a tilt rotary furnace is disclosed. Combustion by the burner forms a heat release profile including a high heat flux region. The positioning of the high heat flux region is controllable by providing a controlled amount of secondary or staged oxidant. The burner is configured and controlled to position a region of high heat flux at a position corresponding to an area requiring greater heating, such as the area of maximum charge depth in the furnace to provide substantially uniform melting and heat distribution.

摘要： An apparatus for heating vessels, the vessels having enclosed spaces therein and controlling air ingress into the enclosed spaces through gaps. The method includes providing a lid structure for the vessel having the enclosed space, the lid structure having a burner assembly mounted therein. The burner is configured to provide a predetermined flame diameter. The vessel and lid structure are mated such that the gap is formed between the vessel and the lid structure. Fuel and oxidant are discharged from the burner assembly under conditions to provide the predetermined flame diameter and impart a flame velocity sufficiently large to create an outward gas flow from the enclosed space through the gap and control air ingress.
