Heating furnace ignition
Thread Content
There are two ways to ignite the heating furnace: one is to start the blower first, adjust the negative pressure in the furnace chamber, and then proceed with ignition； Another approach is to start the ignition using natural ventilation first, and then activate the blower fans and put the waste heat recovery system into use. I wonder which one everyone usually uses, and what are its advantages and disadvantages?
The second one. . . . . . . .
Why not use the first one? Wouldn’t it be better to get it done in one step?
The second method. . . . . . . . . . .
Either method works; natural ventilation for ignition is simpler, while forced ventilation for ignition is somewhat more complicated.
Secondly, in my opinion, the second ignition method, which is natural ventilation ignition, features stable airflow, making it easier to achieve successful ignition. If the first method is used, the flame of the eternal light may be blown out due to its small size. Moreover, when ignition begins, there are usually slight fluctuations in the fuel gas supply to the main burner; if it goes out, it is necessary to purge it again, which is rather troublesome.
We use the first method. Compared to the two, it is more difficult to ignite with the first method, while it is easier to ignite with the second one.
