A burner/emitter/recuperator assembly for providing a high temperature radiant emitting surface, includes an elongated fuel pipe in communication with a fuel source and extending toward the combustion chamber, and adapted to flow fuel from the fuel source to a nozzle end of the fuel pipe proximate the combustion chamber, a primary air pipe disposed around the fuel pipe and in communication with a relatively cool primary air source, a nozzle end of the primary air pipe being substantially coincident with the nozzle end of the fuel pipe, and a recuperator for preheating secondary air disposed around a distal portion of the primary air pipe and in communication with a secondary air source and a swirler downstream of the recuperator. The relatively cool air from the primary air source and fuel from the fuel source flow through the primary air pipe and the fuel pipe, respectively, and mix with the hot air from the recuperator and swirler, exterior to the fuel nozzle and the primary air pipe nozzle end, to maintain a relatively cool fuel pipe nozzle end, and a relatively hot flame in the combustion chamber.
