Abstract: A gas burner for burning a high velocity gas to produce an external flame having a homogeneous front portion and using gas injecting means having a nozzle connected to a source of inflammable gas under pressure and an air passage adapted to create through a tube a flow of air and inflammable gas at high speed which is injected in an adaptation chamber connected to the tube and provided with an internal curved diffusion grill and two external deflectors, the diffusion grill being positioned so that the walls of the adaptation chamber are maintained at the temperature of the environment during combustion of the gas.
