How to purge the horizontal pipes in the coke oven basement?
Thread Content
The purification of chemical processes in our factory is not good, and there is high resistance in the horizontal pipes in the basement. How can these horizontal pipes be cleaned?
Using compressed air for purging also works well
It can be cleaned with a jet; it has high pressure and excellent results.
We have encountered similar situations as well; at the beginning of operation, the chemical processing facilities were not fully equipped, and the gas was not purified. The gas contained impurities such as naphthalene and tar, which could easily clog the horizontal pipes, especially at the nozzles. The methods for cleaning this issue are as follows: first, remove the nozzle and heat it up. The effect is good. Second, it’s the simplest solution: replace the pipes that are severely clogged. III. Mix gas with air, heat it in a horizontal tube, and then purge it with steam. The effect is good. Just make sure to consider the security aspects carefully
Our company conducts cleaning every three years: the horizontal pipes are removed and taken out of the basement, where they are burned using gas and compressed air to assist with the combustion process. But it causes some damage to the horizontal tube.
Hello: Could you explain the specific steps?

Remove the four-way connector, as well as the inkjet printer, and take them to the top of the furnace to burn them; afterwards clean the area. Take down the large horizontal pipe, carry it outside the basement, connect gas to it using rubber hoses, and then mix it with air for combustion in order to clean the large horizontal pipe. Be careful to ensure safety and avoid damaging the pipe due to overheating.
After the replacement is complete, remove the horizontal pipe, eccentric tee, orifice plate (or nozzle), and lower nozzle, carry them to a safe location, burn off the deposits using welding or gas welding (be careful to prevent fires), and then reinstall them.
I was wondering why you don’t establish a system to insert a horizontal pipe and use steam to clean it out after some time?
It seems that the methods everyone uses are more or less the same.
After the horizontal pipe that needs to be cleaned stops receiving gas supply, the corresponding control valves are closed, the blind flanges at both ends of the pipe are removed, and it is cleaned using a specialized pipeline cleaner (high-pressure water gun); this method works well – that’s how we do it
It’s better to use burning; the results are excellent
Previously, gas or steam was generally used for cleaning, but nowadays specialized pipe cleaners (high-pressure water guns) yield the best results without polluting the environment.
4# gfhhj555 Could you explain the specific procedures for using gas and air? It is purged during the downward airflow; both ends of the horizontal tube are opened, and burning starts from one end.
