PROBLEM TO BE SOLVED: To provide a combustion method for forming a tubular flame, which can form such a tubular flame properly as floats from the inner face of a combustion chamber.;SOLUTION: A side part introduction gas is introduced in a tangential direction of an inner surface of a combustion chamber N1 into the inside of a cylindrical combustion chamber N1 having one end closed, from an introduction port 7 opened in the side surface part of the cylindrical combustion chamber N1, and an end part introduction gas is introduced from the end part of the closed side of the combustion chamber N1 along the cylindrical shaft center direction of the combustion chamber N1 into the cylinder shaft part of the combustion chamber N1. The oxygen ratio indicating the ratio of the actual oxygen amount contained in the side part introduction gas to the stoichiometric oxygen amount of the fuel contained in the side introduction gas is set at a combustion restricting oxygen ratio lower than the lower limit, at which the fuel can burn. At the same time, the introduction amount of the end part introduction gas is determined so that the oxygen ratio indicating the ratio of the actual oxygen amount, which is obtained by adding each oxygen amount contained in the side part introduction gas and the end part introduction gas, may be a burning oxygen ratio higher than the combustion limiting oxygen ratio with respect to the stoichiometric oxygen amount of the fuel contained in the side introduction gas.;COPYRIGHT: (C)2015,JPO&INPIT
