Abstract
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.
