Problems with using flame arrester of heating furnace
Thread Content
Have you ever encountered the phenomenon that the flame arrester of your on-site heating furnace is often blocked? If you want to expand the inner core of the flame arrester, what factors need to be considered.
In addition to preventing backfire in the heating furnace, the flame arrester also plays a role in filtering sulfide and impurities in the fuel gas.
There is no need to expand, wouldn't it be nice to add two more? Can be switched.
Do not expand, as expansion will have an impact on fire resistance. A bypass can be added. Use alternately.
It’s just that traffic jams are quite frequent at the moment and the labor intensity is too high. I wonder if any of you have experienced this before.
If you encounter it, don't modify it at will. If you have the opportunity, add a spare set.
Agree with this point of view, we should start by solving the impurities in the fuel gas. You can consider adding a deliquidating tank in front and a filter on the top to separate the liquid.
Reply to 7# david68 There is usually a deliquifying tank in front of the fuel gas, and the gas pipelines will also corrode and produce impurities, which is difficult to prevent.
So how do you deal with it? Just added a spare flame arrester? ! What are your main impurities? From what we can see, there are black things that look like burnt powder and grayish-white things that look like salts. We now have two sets of flame arresters, but there is no way to deal with them like this often, and it was rarely done before. It’s just that it’s relatively concentrated at the moment, and it would be great if there was a complete solution.
The main problem is the raw material, and solving this is fundamental. There is a backup, it is just convenient to switch and clean.
