Zone-controlled radiant burners are provided for retrofit installation in existing heaters. The burners comprise hollow cylindrical fiber matrix layers with baffles forming separate plena. A main stream of pre-mixed fuel and air is directed into the middle plenum, with the mixture flowing through the fiber matrix layer and incandescently combusting on the active surface zones to radiantly heat the tube coils. A reduced flow of fuel/air mixture, or only air, is directed into the remaining plenum so that the surrounding surface zones are combustibly less active or inactive to avoid destructive overheating of the burner surfaces.
