    摘要: 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air are discharged from the burner into a process chamber, and a nonfiring cycle in which a quantity of gas is withdrawn from the process chamber through a regenerative bed associated with the burner.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 A second step of responding to the detected temperature reduces the quantity of gas to be withdrawn from the process chamber through the regenerative bed in a subsequent nonfiring cycle.

    摘要: A combustion system includes a combustion chamber. A fan is connected to the combustion chamber. The fan has a spin velocity. A burner is adjacent the combustion chamber. The burner defines one or more flame openings. Each flame opening has a cross section. An obstacle is associated with each of the one or more flame openings. Each obstacle is within the combustion chamber. A mixture of fuel gas and air having a mixture temperature is discharged at a discharge velocity from the one or more flame openings. A flame is positioned along the burner substantially detached from the one or more openings. A flame position sensor senses the position of the flame and generates a flame position signal based on the sensed position of the flame. A control processor maintains the flame around a prefixed optimum position by controlling a characteristic variable quantity of the mixture based on the flame position signal. The characteristic variable quantity is selected from a premixture rate value of the mixture, the discharge velocity, and the mixture temperature upstream of the flame. The discharge velocity is modified by varying the cross section of the flame openings and the spin velocity of the fan.
