Abstract:
A radiative recuperator preheats oxidant and/or fuel for combustion at one or more burners of a furnace. The recuperator includes a duct, at least portions of which comprise a material having a thermal conductivity of greater than 1 W/(m·K), preferably greater than 3 W/(m·K), that receives hot flue gas produced by the burner(s). The duct radiatively transfers heat to oxidant or fuel (for preheating) flowing through one or more metallic pipes disposed in between the duct and an insulating wall.

Claim (Index 10):
The furnace of  claim 1 , wherein some portions of the duct are comprised of the material having a thermal conductivity of more than 1 W/(m\u00b7K) and remaining portions of the duct are comprised of a material having a thermal conductivity of less than or equal to 1 W/(m\u00b7K).
