PURPOSE:To obtain the slit type burner which does not obstructed the combustibility and does not reduced the combustion efficiency regardless of the variation of fuel gas quantity and a burning air quantity by a method wherein an adjusting nozzle which able to adjust the aperture of a slit type injecting opening is provided at the top of a throttle part. CONSTITUTION:A flow passage 11 for a burning air is formed at the both sides of a flow passage 12 for fuel gas, a throttle part 13 is provided at the top of said passages, then a slit type injecting opening 14 is formed at the top end. A fuel gas is supplied from a gas supplying pipe 15 at the central part, a burning air is supplied from the both sides air supplying pipes 16. An adjusting nozzle 17 is provided at the top of the throttle part 13, the aperture of the injecting opening 14 is adjusted with the nozzle 17. Thereby, the combustibility is not obstructed regardless of the variation of the burning gas quantity and the burning air quantity, and the combustion efficiency is not reduced. |
