ABSTRACT:
An insulated refractory shield is provided to reduce heat loss through the exterior surface of the refractory shield while at the same time a cooling fluid is directed over the cast metallic refractory supports and hanger means through apertures in the hanger tube. Modular insulation units are provided and are retained between the exterior face of the refractory bricks and the hanger tube by means of specialized wedges and support clips.
