摘要： A method for decoking the inner wall of a metal cavity, comprising pressurizing the metal cavity closely and depressurizing the metal cavity rapidly. In the above-mentioned decoking method, by firstly pressurizing the metal cavity and then depressurizing same rapidly, substances such as volatile hydrocarbons, water and so on inside a coke block are vaporized rapidly due to the drastic change in the pressure difference, and then the coke block is burst and detached from the inner wall of the metal cavity, and finally the decoking work is completed. The above-mentioned decoking method is rapid, simple and easy to operate, and the decoking efficiency can be greatly improved.
