摘要： The invention relates to a radiant device with a burner of the nullglove fingernull type, comprising an exchanger (3) for heating air (T1) by the burned gases (T2), a furnace tube (6) drilled with air-intake orifices (60) and terminated by a nozzle (61) disposed facing a recirculation tube (4), and a central gas-injection tube (7). According to the invention, the central injection tube (7) is fed with gaseous fluids in proportions that can be regulated by means of one or to valves (710, 720), via two conduits (71, 72), the first (71) of which transports at least gas and the second (72) of which transports at least air, and the central injection tube (7) ends at a burner (8), which is disposed in the furnace tube (6) and which discharges at the level of the nozzle (61), this arrangement making it possible to adapt existing devices very easily for the purpose of reduced production of nitrogen oxides.
