ABSTRACT:
A gas burner particularly intended to produce diffusion flames of good emissivity and luminosity in an industrial furnace, for example a reverberation furnace such as may be used in glass making. The burner has a plate forming a burner nozzle having a central through first bore surrounded by a circular array of six smaller diameter second bores. One of the second bores is parallel with the axis of the central first bore. Whereas the other five second bores are each respectively disposed at an acute angle of substantially 22.5.degree. to the axis of the central first bore. Fuel gas is supplied to the central first bore through a central tube and to the second bores through an annular passage between the central tube and a surrounding tube.
