A method includes the steps of operating a regenerative burner in cycles, including a firing cycle in which fuel and combustion air are discharged from the burner into a process chamber, and a nonfiring cycle in which a quantity of gas is withdrawn from the process chamber through a regenerative bed associated with the burner. The method further includes steps of detecting and responding to a temperature that differs from a predetermined temperature at a location in the process chamber. In a first step of responding to the detected temperature, a flue damper system is operated to vary a flow of gas within the process chamber relative to the location of the detected temperature. A second step of responding to the detected temperature reduces the quantity of gas to be withdrawn from the process chamber through the regenerative bed in a subsequent nonfiring cycle.
