<p>A burner in particular a gas burner for e.g. a central heating installation. The burner comprises a mixing zone or a mixing tube 2 and opening therein at its one end at least one injection nozzle 7 for supplying pressurized fuel, in particular a gaseous fuel in drawing at least primary combustion air from the atmosphere. Further, the burner comprises a discharge 12 for combustion gases. At its other end the mixing zone or mixing tube 2 is in communication with a substantially closed combustion chamber 3 which is in communication with the discharge 12 for combustion gases. The walls of said combustion chamber 3 consist of a refractory material having relatively poor heat conduction.</p> |
