Abstract
A recuperative radiant tube heating system in which a recuperator tube telescoped into a radiant tube and over a burner assembly is formed as three interconnected sections to facilitate manufacture of the recuperator tube, to facilitate assembly of the recuperator tube with the burner head of the burner assembly and to enable easy replacement of that portion of the recuperator tube which is most susceptible to burn out. The burner head includes a nozzle having gas discharge ports which are angled in such a manner as to effect good mixing of the gas with combustion air while reducing the likelihood of the ports becoming clogged with carbon.
