PROBLEM TO BE SOLVED: To widen a combustion range as compared with a burner for ignition, and to improve a flame stabilizing property by providing a burner port made from a cloth-shaped body made of heat-resistance metal fiber at the tip of a pipe with a small diameter. SOLUTION: At the tip of a small-diameter pipe with desired length, a cloth- shaped body 2 is welded, where the cloth-shaped body 2 is formed into metal fiber knitting or the like by allowing heat-resistance metal fiber where heat- resistance alloy such as heat-resistance steel and Inconel is formed in a fiber shape to be subjected to knitting machining and fabric machining. The cloth- shaped body 2 operates as a burner port part 3 being machined in a column shape. Then, at the upstream side of the burner port part 3, a mixing part 7 consisting of a fuel nozzle 5 and an air suction hole 6 is provided for performing Bunsen system combustion, thus widening a combustion range as compared with a burner for ignition, achieving an improved flame stabilizing property, and improving stability.
