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 31):
The method of  claim 16 , wherein the furnace is a metal melting furnace and the injected fuel and oxidant are combusted in the combustion space thereby heating solid and/or molten metal.
