Abstract
1,269,938. Gas burners. QUADRANT ENG. CO.- Ltd. 4 June, 1969 [6 June, 1968], No. 26990/68. Heading F4T. A gas burner especially suitable for natural gas includes an array of outlet passages which array comprises at least one passage e.g. 14 for the supply of a mixture of combustible gas and air to a main flame in use and further passages 18, 19, 22 for the supply of the mixture to a keeper flame or flames which will substantially surround the main flame in use, the keeper flame supply passages including at least one inner passage e.g. 19 and at least one outer passage e.g. 22 arranged at mutually different spacings outwardly from the main flame supply passage 14, at least one expansion chamber e.g. 20 situated upstream of and adjacent to the keeper flame passages 18, 19, 22 whereby the mixture supplied to the keeper flame(s) will always be at a substantially lower pressure than that supplied to the main flame, and flow restricting means 23 in the expansion chamber 20 arranged so to further reduce the pressure of the mixture supplied to the outer keeper flame passage 22 as compared with that supplied to the inner keeper flame passage 19. In Fig. 3, the keeper flame passages 18, 19, 22 are formed as coaxial rings in a head element 10 of a head 7 which is screwed into the outlet of the burner. The expansion chamber 20 is situated in the head element 10 and is formed as an annulus axially between a ring of inlet passages 16 and the rings of keeper flame passages 18, 19, 22, and includes flow restricting means in the form of wound metal gauze 23: downstream of the ring of inlet passages 16 are a series of spaced metal gauze discs 12 to smooth the flow of the mixture. The outermost ring of passages 22 is defined in use by grooves in the element 10 and an adjacent wall of the burner when the head 7 is mounted therein. The invention is also suitable for burner having a main flame which is broad and flat and wherein keeper flame supply passages are formed on each elongated side of the main flame supply passage.
