Abstract
A burner block for an industrial furnace is resiliently seated in a hollow annular member, the latter being made of a metal such as stainless steel and the burner block being made of a refractory material. Because of the resilient mounting, the burner block is seated firmly in the annular member even though these two parts have different rates of thermal expansion. In addition, a cooling fluid is circulated within the interior of the annular member to cool the latter so that the furnace may operate at a temperature which is well above the temperature at which the annular member loses its structural integrity. All of this permits the burner block assembly to be mounted effectively on the metal outer shell of the furnace without relying upon the refractory lining of the furnace for support.
