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.
Claims19
A gas burner comprising a nozzle formed with a plurality of first and second through apertures for the passage of fuel gas therethrough, there being a first aperture surrounded by a plurality of second apertures disposed in an array about the first aperture, the cross-sectional area of the first aperture being greater than the cross-sectional area of any said second aperture, at least one said second aperture facing along a direction which is at an acute angle to a direction along which said first aperture faces, first and second tube means being arranged for supplying fuel gas respectively to said first aperture and said second apertures for said gas to emerge from said first and second apertures, said first aperture opening into the first tube means and said second apertures opening into said second tube means, and the first tube means being provided with gas flow restriction means.
A furnace having at least one gas burner comprising a nozzle formed with a plurality of first and second through apertures for the passage of fuel gas therethrough, there being a first aperture surrounded by a plurality of second apertures disposed in an array about the first aperture, the cross-sectional area of the first aperture being greater than the cross-sectional area of any said second aperture, at least one said second aperture facing along a direction which is at an acute angle to a direction along which said first aperture faces, first and second tube means being arranged for supplying fuel gas respectively to said first aperture and said second apertures for said gas to emerge from said first and second apertures, said first aperture opening into the first tube means and said second apertures opening into said second tube means, and the first tube means being provided with gas flow restriction means.
A furnace as claimed in claim 12, arranged for combustion air to issue into a combustion chamber, and the flow of said issuing air being arranged to be adjacent to said burner.
