Approximately 500 kg of carbon, tar, clinker, and other firing accretions attached to the furnace inner wall, furnace lid, and gas passages
/Cm2 or more of high-pressure water is injected to cause a small local explosion of water vapor and a thermal shock due to rapid contraction of the surface of the deposit, and to apply a frictional force between the deposit and the porous surface of the deposit. At the very least, we proposed a furnace cleaning method that would accelerate the crushing and peeling of the town's kimonos.

点にある。The present invention relates to a high-water injection lance used in such a method for cleaning the inside of a furnace, and includes a high-pressure water injection water injection pipe 1 with a tip nozzle 2 surrounding it concentrically with the outer periphery of the water injection pipe 1. It is characterized by being equipped with a bell-shaped guide member 3 with an open end, and its purpose is to effectively apply high pressure to the attached material without damaging the brick surface of the furnace wall. The object of the present invention is to provide a new and useful high-pressure water injection lance for cleaning the inside of a furnace that injects water.

。As mentioned above, in the lance according to the present invention, a bell-shaped guide member 3 is attached to the outer periphery of the high-pressure water injection pipe 1 concentrically with the main body, and the tip nozzle 2 of the injection pipe 1 is connected by the guide member 3. The lance of the present invention is inserted into the furnace or gas passage, and high-pressure water is injected from the tip nozzle 2 of the high-pressure water injection pipe 1 onto the firing accretions such as carbon attached to the furnace wall a, etc. In this case, the bell-shaped guide member 3 is in contact with the furnace wall a, and the tip nozzle 2 of the high-pressure water injection pipe 1 is always in contact with the furnace wall a.
Since the high-pressure water is always injected from the brick surface at a constant distance t from the brick surface, the brick surface will not be damaged by being directly hit by the high-pressure water.

ウォーターブラスト作業に適用されるものである。The lance of this project is not only cylindrical, but can also be used in furnaces of various shapes.
Alternatively, it is capable of removing only the deposits on the inner surface without damaging the inner surface of gas passages, etc., and is useful for removing carbon from riser pipes, charging ports, ceilings, and oven walls of coke ovens.
This applies to water blasting work.
