Abstract
An apparatus and method are provided for removing deposits from material such as drill pipe by subjecting such material to extremely high temperatures in a flame fired furnace. Heated air passing over the material carries with it the volatized deposits and is recirculated within the furnace. As the deposit laden air is recirculated to the burner, the deposits are burned in the flame, thus substantially eliminating the exhaust of contaminants into the surrounding atmosphere.
