Abstract

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.

All of these devices use only one of mechanical energy and thermal energy to remove deposits. On the other hand,
No. 1 describes a device that melts metal by injecting iron powder into a flame. This device is used in continuous casting equipment, and is not a device for removing deposits, but it uses both thermal energy from flame and combustion of iron powder, and mechanical energy from collision of iron powder. Therefore, it is considered that the removal efficiency (fusion cutting efficiency) is higher than the above-mentioned three conventional techniques. Therefore, it is conceivable that a device similar to or similar to this device could be used to remove deposits from metal processing containers.

[Problem to be solved by the invention] However, in the device of Utility Model Publication No. 58-41016,
Multiple iron powder nozzles are fixed around a burner that injects flame. In this structure, the iron powder is sprayed onto the object around the flame, so some of the iron powder from each nozzle may be dispersed away from the flame or at a location relatively far from the flame (where the temperature is relatively low). collides with an object at position). Therefore, in the work of removing deposits, there is a possibility that work efficiency cannot be sufficiently increased.

According to the above configuration, a generally cylindrical flame is blown onto the deposit from the flame fluid passage, thereby heating the deposit in a generally circular range (heating range) having a certain width. On the other hand, the iron powder injected from the iron powder passage mixes with oxygen injected from the oxygen passage, is accelerated by the oxygen, and collides intensively at the center of the heating range. Then, those iron powder and oxygen flow from the outlet of the corresponding passage through the space within the concave surface of the burner tip, and from that space further to the external space (
After flowing through the space between the burner tip and the surface of the deposit, it collides with the deposit. That is, the iron powder and oxygen for iron powder collide with the deposit after passing a relatively long distance. Therefore, the entire iron powder is sufficiently accelerated and mixed with oxygen to be combusted to a desired state. Also, as described above, the mixture of iron powder and oxygen collides with the center of the area that has been sufficiently heated by the flame. As a result, the deposits can be melted and destroyed by fully utilizing both the mechanical energy (collision energy) and thermal energy of the iron powder, oxygen, and flame.
