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 11):
The furnace of  claim 1 , wherein:\n the duct is comprised of four pillars disposed at a respective four corners of the duct and four duct portions each one of which extends between a respective pair of pillars so that a first of the four duct portions is parallel to a third of the four duct portions and a second of the four duct portions is perpendicular to the first of the four duct portions and parallel to a fourth of the four duct portions; the one or more insulating walls comprises corresponding first, second, third, and fourth insulating walls that extend parallel to the first, second, third, and fourth duct portions, respectively so as to define first, second, third, and fourth non-reactive gas spaces, respectively; a first set of one or more of the metallic pipes extends through the first non-reactive gas space; a second set of one or more of the metallic pipes extends through the second non-reactive gas space; a third set of one or more of the metallic pipes extends through the third non-reactive gas space; a third set of one or more of the metallic pipes extends through the third non-reactive gas space; and each of the four duct portions is comprised of the material having a thermal conductivity of more than 1 W/(m\u00b7K).
