ABSTRACT:
A radiant burndown tube for furnaces which have a chamber sealable from the ambient atmosphere and in which there is a combustible gas. The burndown tube is divided into three functional areas; the burner leg, the exhaust leg and a tube portion. The tube portion is located within the furnace chamber. There is an inlet where the combustible gas from the furnace chamber is drawn into the burndown tube. The combustible gas is mixed with air and ignited in the tube and the combustion products are exhausted via the exhaust leg. Thus, the heat energy normally lost in the burndown of combustible furnace exhaust gases outside of the furnace is captured and used to provide additional heat to the furnace.
