Abstract

PURPOSE: To shorten the time required from lighting to stable burning and reduce the generation of soot during lighting and putting out the fire by a method wherein recesses are provided at the portions where the vaporizing air contact with a vaporizing wick.

CONSTITUTION: While air flowed in from a vaporizing air inlet hole 2a impinges on a vaporizing wock 4, the air develops turbulence effected by the presence of the recesses 5 as shown by arrow A. Consequently, the gasified fuel wafting on the surroundings is caught into said turbulence A to mix fully with air to allow to have a small flame. Non-mixed gas layer is disappeard from the surroundings of said small flame by agitating and mixing by the turbulence A, the phenomenon of generating large amount of soot by pyrolysis of fuel gas can be avoided. While putting out the fire, the amount of fuel gas vaporized from the wick 4 is gradually dissipated by stopping the fuel supply, and the large amount is burnt in the neighborhood of the vaporizing wick 4 same as the initial lighting, agitation and mixing actions of air and fuel caused by the recess 5 are developed even in this condition, enabling to reduce the soot generation by the pyrolysis of non-mixing gas.
