Cleaning the coke oven gas pipeline is crucial to ensure the stable operation of the coke oven system. Coke oven gas contains a large amount of tar and other impurities, such as naphthalene, phenol, etc. The deposition of these substances in the pipeline will increase the resistance of the pipeline and reduce the gas transmission efficiency.
