Somehow, the air duct at the inlet of the exhaust fan exploded.
A gas explosion definitely requires the gas to reach its explosive limit and the presence of an ignition source: common ignition sources include fans that are not explosion-proof or situations where high flow rates generate static electricity； The gas reaches the explosive limit: Our company’s solution is to install a dilution fan on the exhaust pipeline.
Control the wind speed of gases containing flammable substances, and ensure proper static grounding of fans, pipes, etc. Most of them are accidents caused by static electricity
Consider adding an online combustible gas analyzer to control a vent valve while the RTO is offline.
In our workshop, we install combustible gas detectors at the fan outlet, and then introduce an air line at the fan inlet to dilute the concentration of combustible gases
I would like to see what it looks like after being fried. When frying inside a tube, it comes down to the explosion limit and the ignition source. The concentration wasn’t controlled properly; usually, it’s an issue caused by too high a concentration
It’s fixed now; there’s no on-site issue anymore, hehe.
Blast it, then repair it; repair it, then blast it—such is the fate of combustible gas collection pipes. To save trouble, it’s necessary to ensure proper grounding and conduct static electricity testing on the pipelines. The method of diluting the concentration of flammable gases needs to be discussed; concentrated waste gas is conducive to combustion, while diluted waste gas results in high combustion costs.
Both combustion and explosion are essentially oxidation reactions of combustible substances in air. The difference lies in the different oxidation rates. Flammable materials, oxidizers, and an ignition source are the three basic conditions for combustion and explosion. Collectively referred to as the three elements.
