If it is switched to burning gas, this problem will not occur
It’s mainly a problem with the fuel gun – for example, its position isn’t at the center, and some nozzles are blocked. The heavier the fuel oil, the more likely it is to clog
Gas nozzles can also become clogged or suffer from carbon buildup, mainly due to incomplete combustion. This may be caused by design flaws or an inadequate supply of air, leading to the accumulation of carbon deposits; however, by modifying the nozzle to a premixed type, a large portion of these carbon buildup problems can be avoided. Of course, coking can also occur if there is liquid present or if the installation is not vertical.
What kind of fuel are you using? If it’s oil, this is what will happen; if you use dry gas, carbon buildup can still occur if there’s oil present in the dry gas
We were burning gas; the carbon buildup caused the fire to go out, and the gas leaked out through the secondary air valve. I don’t know how long it had been leaking, but fortunately I noticed it. It’s a shame that it caught fire just as I was about to report it – it was a really scary moment… Luckily, the wind was strong; otherwise, an explosion would have occurred and I would have been trapped under the furnace forever….
It is mainly the atomization effect of the firearm; a poor atomization effect can easily lead to coking； The operation also has an impact; an improper distribution of primary and secondary air, as well as inadequate air supply levels and negative pressure values, can easily lead to the formation of droplets at the burner tip, resulting in coking
