Abstract
1,259,351. Aerated gas burner. GAS COUNCIL. 7 July, 1970 [14 April, 1969], No.18935/69. Heading F4T. The two slotted gas ports 9 of an atmospheric gas burner are arranged with equal slopes so that the angle included between their axes is between 20 and 60 degrees, but preferably between 30 and 40 degrees, so that the gas jets impinge upon each other and mixing between air and gas is promoted by the resulting turbulence. The burner comprises a gas injector 1 with a supply bore 6 communicating with the gas ports 9 through a bore 7, and a burner body 12 with upper and lower portions 13, 14. The lower portion 14 has a Venturi restriction 15 below the point of intersection of the gas port axes and fits over the head 3 of the injector with lugs 16, leaving gaps 17 which form the air inlets. The upper portion 14 is rotatably mounted on the lower portion and its opposite walls 20 are flared outwards producing a flat, arcuate, slotted flame port 23 which is narrow relative to its depth, thus producing a back pressure in the mixing chamber which promotes mixing and stabilizes the flame.
