Switch is smoking
Thread Content
Are the coke ovens here smoking after being replaced? Keeping the terminal pressure at 2750 PA extended the exchange time, but it doesn’t seem to have been very effective. I’m seeking advice from everyone – is there any solution?
What kind of smoke is it? Black smoke, yellow smoke, or white vapor?
There’s a leak in your coke oven; control the pressure at the five points of the coke oven, and things will get better gradually.
There’s no leakage; it’s just black smoke
There might be a leak in your heating system. There is black smoke. You probably use explosives at the bottom of your furnace too! ! Check it carefully. There must be
Here too, it has been smoking non-stop since work started; the amount of smoke varies sometimes more and sometimes less, and there are many factors that influence this
First, consider coke oven leakage; if not, carefully check whether the switching cock is fully closed when it is in the center position
Why is the terminal pressure controlled at such a high level?
The gas pressure is too high, and the suction is too low
Smoking may be due to a leak somewhere in the furnace; it is necessary to carefully check the integrity of the furnace. It could also be caused by an excessive increase in gas pressure at the moment of direction change, resulting in an oversized gas flow. The excess air coefficient was probably not appropriate to begin with, and as a result of changes in the temperature of the regenerative chamber after the direction change, the suction force decreases. There are many factors that affect smoke emission from chimneys, and a thorough investigation is necessary!
