PURPOSE:To improve the removing efficiency of stuck material by setting direction of fluid passage for flame so that the fluid from the passage reaches the position enveloping the specific range. CONSTITUTION:By blowing the cylindrical flame from the fluid passages 5, 6 for flame to the stuck material 40, the stuck material 40 is heated in the circular range. On the other hand, iron powder injected from an iron powder passage 3 is mixed with oxygen injected from an oxygen passage 4 and accelerated with the oxygen and caused to intensively collide to the center part in the heating range. Then, these iron powder and oxygen are caused to flow into a space of recessed part 31 at tip part of a burner from outlets of the corresponding passages 3, 4, and after further flowing outer space from this space, these are made to collide against the stuck material 40. Therefore, the whole iron powder is sufficiently accelerated with the oxygen during passing through these and sufficiently mixed with the oxygen and burnt to the desired condition. In this result, by sufficiently utilizing both of mechanical energy and thermally energy of the iron powder, oxygen and flame, the melting and breakage of the stuck material 40 can be executed.
