Furnace with radiant burndown tube
A method of burning combustible gas atmosphere in a furnace having at least one radiant burndown tube is described. The furnace has a furnace wall, a sealed furnace chamber, a conduit through the furnace wall, and the radiant burndown tube having a tube portion within the furnace chamber, the tube portion having a burner end and an exhast end, and exhaust means connected to the exhaust end, a burner leg connected to the burner end, the burner leg having an ignition means and an air nozzle, comrising the steps of: locating the burner end so that there is an annular space inlet between the burner end and the conduit; introducing air from the air nozzle into the burner end of the tube portion of the radiant burndown tube; drawing the combustible gas from the furnace chamber through the inlet into the tube portion; mixing the air and the combustible gas within the tube portion; igniting the air and combustible gas mixture within the tube portion; controlling the flow of air through the air nozzle to insure entrainment of the combustible gas in the air within the tube portion for uniform burning with a relatively low temperature spread along the length of the tube portion; exhausting the contents of the tube portion to an exhaust means.
