Abstract

A gas burner for a heating furnace with at least one burner pipe (1) with flame openings (7). An intake opening (5) is provided in which primary air enters and wherein burnable gas enters through a gas nozzle (4) penetrating into the intake opening (5). The percentage of primary air remains extensively unaffected during changes in the gas pressure occurring as a consequence of a change in the nature of the gas. The gas nozzle (4) has within the burner pipe (1) either only at least one gas opening (16), which is radial to the longitudinal axis (A) of the burner pipe (1), wherein the primary air can be fed to the burner pipe (1) via a blower (12), or--in the case of a design as an atmospheric gas burner--gas openings (16), which are radial to the longitudinal axis (A) of the burner pipe (1), as well as a displaceable nozzle part (21), which forms a gas opening (23) which is axial to the longitudinal axis (A) of the burner pipe (1) and opens the radial gas openings (16) during increasing gas pressure and closes them at low gas pressure.
