Abstract (en)
[origin: EP1271052A1] The radiant heater, comprising a tube (5) with an inner gas burner (8) and heat exchanger (3) for heating a chamber (1) with an insulated wall (10), has a central gas injection tube (7) fed by two conduits (71, 72), one carrying a combustible gas and the other air in variable proportions. The conduits are fitted with valves (710, 720) to control the flow of gas and air to the burner (8) inside a furnace tube (6) with an outlet nozzle (61), and the system is easily adapted to fit existing apparatus to reduce the output of nitrogen oxides.
