The flame at the top of a burner enters the burner channel when a mixture is stopped quickly. The quenching distance measured by a burner method means the minimum width of the channel through which the flame can pass. The problems about three measurement methods are discussed with optical observation in this paper, and it is found that a tapering burner method is the most recommendable of these measurement methods are discussed with optical observation in this paper, and it is found that a tapering burner method is the most recommendable of these methods for the following reasons. When the mixture is not spark-ignited but the flame is held at the top of the burner, method with spark ignition, abrupt change of cross-sectional area of the flame entrance often prevents the flame from entering the channel. At that time, the flame does not interact with the surface of the channel. The above defects are eliminated in the tapering burner method with spark ignition.
