PURPOSE:To prevent a mixing pipe from blocking caused by dust by a method wherein the center line of the mixing pipe is arranged to be located at the upper position than that of the lengthwise direction of a burner main body. CONSTITUTION:Floating dust in a room is flowed into a burner main body 8 along an arrow mark 17 around a nozzle 13 via a mixing pipe 11. Hereupon, the location of the center line of the mixing pipe 11 in the burner main body 8 is deviated upward. A space 14 is formed larger, and the larger space is formed at the front and lower side area of the opening end part of the outlet side of the mixing pipe 11, therefore, a cotton dust 15 flowed into the mixing pipe 11 is flowed fast through the mixing pipe 11 where the flowing speed is fast, then the dust is accumulated at the front and lower side area of the opening end part of the outlet side. Thereby, the inside of the mixing pipe is prevented from the blocking caused by the cotton dust, accordingly, the steady red hot temperature and perfect burning can be maintained over a long time. |
