PROBLEM TO BE SOLVED: To provide a tubular flame burner using liquid fuel. SOLUTION: This tubular flame burner has a nozzle whose one end is opened and which blows oxygen containing gas into the other end part and a combustion chamber provided with an injection valve for blowing liquid fuel in. The nozzle has a slit-like opening part along the direction of pipe axis and blows oxygen containing gas into the direction of tangent on its internal wall face. The injection valve has a shielding structure for shielding an injection port from oxygen containing gas, preferably, a part including liquid fuel injected like a funnel from the injection valve without bringing it into contact with its internal wall and surrounding a part around a blow-in port of the injection valve like a funnel in its tip part. The injection port of the injection valve is positioned on the upstream side more than the opening part of the nozzle. COPYRIGHT: (C)2007,JPO&INPIT
