Recently, we encountered a problem with our furnace: the burner started to vibrate. This had not happened before. I suspect that tempering could be the cause, but this is not possible in our case, as the furnace pressure is 2 Kpa and the gas pressure is 1 kilogram; therefore, tempering can be ruled out. Additionally, vibration due to decoupling is also unlikely, as the pressure is very low, meaning the gas velocity cannot exceed the flame velocity. After the vibration, I lower the wind and gas level, and then the vibration stops. I think it’s a problem with the burner. Have any of you sea friends encountered this issue? If so, please give me some advice
1. “Because the furnace pressure is 2 Kpa, the gas pressure is 1 kilogram, and backfire is eliminated” – this gas pressure refers to the value before the flow control valve, and it has nothing to do with the pressure after the flow control valve. 2. “After vibration occurs, I reduce the wind and gas flow, and then the vibration stops; I always think it’s a problem with the burner.” – It is recommended to have the burner manufacturer come and take a look; I have never encountered such a situation myself.
Is the furnace pressure 2 kPa? Is it a sulfur production furnace or an incinerator? It is recommended to check whether there is any blockage in the gas burner
Our gas pressure reading is taken after the flow restrictor, and it shows 1 kilogram
For the sulfur production furnace, I also think the pressure is very low – at least around 10-20 KPa – and the main burner isn’t blocked
Does this phenomenon occur frequently or only under low load?
If this problem occurs with a newly installed unit, it is still recommended that the designer re-evaluate the design of the gas burner and air distribution system. This phenomenon has been encountered before: once acidic gases were introduced, everything returned to normal.
Bro, there’s an earthquake – hurry and run!
It happened while heating the furnace; I went in to take a look today and found that the burner was a bit off
The calorific value of the gas is very high; I control it to use the minimum amount, with an acid gas load of 30, and the gas is adjusted according to its calorific value. I went in to take a look today and the burner is a bit off; it’s very likely that the burner is misaligned. I’ll wait for the furnace manufacturer to provide a technical report for further analysis
That’s good too; in case of an earthquake, run away quickly
