Radiation shield and method for shielding a furnace convection section

摘要

Apparatus and method for substantially blocking the "line-of-sight" between a radiant section of a furnace and a convection section positioned above the radiant section, while at the same time permitting flue gases from the radiant section to travel substantially freely through the shield. The shield may be composed of a plurality of staggered bodies. In a preferred embodiment the bodies are staggered plates, composed of insulating material. The staggered plates are supported by hangers that are hung from convection tubes in the convection section. In another embodiment the staggered bodies are tubes or rods.
