BURNER

PURPOSE:To curtail operation cost, eliminate restrictions on installation sites, and reduce production cost as well, by forming an ejection section in a gas ejection member so that fuel gas may be ejected in a peripheral direction so as to obtain a rotary force, providing air discharge impellers made in one piece with said gas ejection member, and flame maintenance section on the lower stream side of the gas ejection member. CONSTITUTION:As ejection sections 5 are designed so that fuel gas may be ejected in a peripheral direction of a fuel gas pipe 3, a gas ejection member 4 obtains a rotary force in a peripheral direction of the fuel gas pipe 3 from the ejection energy of fuel gas ejected from the ejection section 5, and starts rotary motion. Since the gas ejection member 4 and air discharge impellers 6 are made in one piece construction, the air discharge impellers 6 carry out rotary motion as well. This construction makes it possible to feed combustion air smoothly into an air blow pipe 2 from an opening 7a on the upper stream side of the air blow pipe 2, and mix the fuel gas and the combustion air to a satisfactory extent in a flame maintenance section 10, then start combustion. More specifically, high temperature combustion gas is generated in the air discharge pipe 2. The generated combustion gas is ejected as a hot air from an opening 7b on the lower stream side of said blow pipe 2, which makes it possible to use the hot air for drying and heating service as well.
