PURPOSE:To improve stability of flames as well as to shorten the length of a flame, by arranging a plurality of burner bodies which are composed of a plurality of flame ports arranged in staggered state by the intermediary of a connecting part, while being arranged nearly in parallel, in a gas burner having flame ports in the state of a slit. CONSTITUTION:A gas burner sucks the primary air 16 and mixes fuel gas which is injected from a nozzle 15, in a mixing pipe 17, and the mixed gas is jetted out of a plurality of flame ports 11 and 12 of a duplex burner bodies 9 and 10. The fuel gas is burnt so as to form a flame 18 consisting of the primary flame 19 and the secondary flame 20, receiving a feed of air 21. In this case, the above- mentioned flame ports 11 and 12 are arranged in staggered state to face to the outside and the inside, respectively, by the intermediary of a connecting part 13. With such an arrangement, the same effect as of the interval of the adjacent flame ports, actually being separated, can be obtained, as a result, the secondary air 21 can flow into flame ports in good condition, to improve the stability of a flame, as well as to shorten the length of a flame. |
