Abstract
Gas burner of relatively low power of the blown air and premixture type comprising separate intakes for air and for combustible gas passing into a premixing chamber discharging into a combustion chamber at the level of which the premixture is ignited by means of a lighting electrode, the air intake and combustible gas intake each comprising at least one flow regulating valve. The burner is characterized in that a device having a calibrated orifice of the injector type is provided on the combustible gas intake while a passage of relatively small cross-section, of the diaphragm type, is provided on the air intake. The invention is particularly applicable to installations comprising this burner to serve as a pilot lighting burner.
