White smoke coming from the chimney
Thread Content
There is a lot of white smoke coming from the chimneys; most people say it’s caused by the condensation of water vapor, but there’s also plenty of smoke in summer. Who has a more reasonable explanation?
There is a clear difference between white smoke and white vapor coming from a chimney: water vapor disappears once it reaches a certain height, while smoke forms a long plume that, when there is wind, drifts far away with the wind; in the absence of wind, it rises high into the clouds. Because the smoke coming out of the chimney is at 180 to 240 degrees, and it contains not much water vapor; it can only be seen when the temperature drops below zero degrees. It cannot be seen in spring, summer, or autumn – all that can be seen is smoke. White smoke is actually just due to a small amount of substance; the reflection of light gives it a white appearance, but when there’s more of it, it turns into black smoke.
White smoke may be caused by water accumulation at the bottom of the chimney
If it can be seen in summer as well, there is likely a leak in the furnace body, and thermal inspection is required for repair
We have several furnaces here, two 7M models and one 6M model. The weather is quite hot these days; smoke is emitted both during the day and at night. It’s not that serious, but it’s still visible as white smoke. As the people upstairs said, it might be because the amount of smoke produced is small. . . But what is the real reason?
There is a lot of white smoke coming from the chimneys; most people say it’s caused by the condensation of water vapor, but there’s also plenty of smoke in summer. Who has a more reasonable explanation? The sulfur content in gas is also the main reason for the formation of white smoke, I suppose. Sulfur in gas burns to produce SO2, which is further oxidized to SO3 at high temperatures, and then combines with water vapor to form H2SO4. After the flue gas emitted into the atmosphere mixes with the air, its temperature drops. When the temperature reaches the dew point, the sulfuric acid vapor in the flue gas condenses to form sulfuric acid mist, causing the flue gas to appear white. The higher the sulfur content in the gas, the more SO3 is produced, the higher the flue gas dew point becomes, and the easier it is for white smoke to appear. The lower the exhaust flow velocity, the longer the white smoke will be. The lower the atmospheric temperature and the higher the relative humidity, the more likely white smoke will appear. This is just my personal opinion; please feel free to correct me if there are any mistakes!
What was said upstairs is very good; then how should it be handled? Looking forward to the answer. . . . . .
