A radiant burner is described for use in a process heater. The burner comprises the combination of a fiber matrix shell of elongate cylindrical shape, the matrix having interstitial spaces between the fibers for diffusing fuel and air therethrough. Baffle means divide the internal shell volume into separate plena which extend lengthwise of the shell. Inlet means direct independent streams of gas into the separate plena, with a first one of the plena receiving a first stream comprising a fuel and air mixture which flows through the fiber matrix and flamelessly combusts on the outer surface portion of the shell which surrounds the first plenum forming an active combustion zone to transfer heat outwardly primarily by radiation.
