Abstract

The radiant tube burner for furnaces for heat-treating metallic workpieces under the action of a treatment gas generated by catalytic reaction of a feed gas has a shell tube, which has gas outlet orifices at its end, an inner tube which is coaxially arranged in and at a distance from the shell tube and in which at least one burner tube and an air feed tube are arranged, and also a catalyst bed which at least partially fills the interspace between the shell tube and the inner tube. To improve the controllability of the composition of the treatment gas, it is proposed that at least one burner tube of the radiant tube burner is displaceable in the longitudinal direction thereof.
