Problems encountered during furnace drying in winter
Thread Content
In the early stages of heating the furnace in winter, when the temperature is around 40 degrees, what should be done if water accumulates and freezes in the small flue ducts?
It’s not surprising that the surfaces freeze; it’s mainly because the insulation in the flue corridors and basements isn’t adequate. Once all the doors and windows are properly installed, there won’t be any problems.
Pay close attention to the water accumulation; if a large amount of water flows out, measures should be taken to prevent water from eroding the ash in the small flues, and insulation should be improved along with the suction capacity
Since the moisture inside the coke oven masonry must evaporate before 100°C, the period from room temperature to 100°C is called the drying phase; during this time, the rate of temperature increase should be reduced, and attention should be paid to any water accumulation in the small flues. After the drying period, once the coke oven masonry is completely dry, there will be no water accumulation.
These days, people tend to use coal balls, but there is a risk of carbon monoxide poisoning, which is a problem
Water accumulation and freezing occur in the small flue – do you mean freezing inside it or outside it? If it freezes outside, it doesn’t matter; in the coking plants in the north, stoves are still lit inside the flue stacks. http://bbs.hcbbs.com/attach/swfupload/12010616276586d8b776c3e000.jpg

Excessive water accumulation can lead to the washing away of the mud in the gaps between bricks; be careful with this, and ensure proper insulation in the basement. You can use larger oil drums, burning coal inside them. 2. To increase the suction force, it’s necessary to have a high level of suction before 100 degrees, so as to quickly remove water vapor.
The glass in the flue corridors has been installed; make sure to keep the corridors warm by placing several heaters in the basement, distributing them evenly so that the heat is spread out rather than concentrated in one area. (Be careful not to suffer from carbon monoxide poisoning – I’ve encountered such situations before, and many people ended up poisoned by carbon monoxide.) Increase the suction power of the flues appropriately, but not too much, to prevent the heat generated by the heaters from dissipating too quickly.
Pay attention to keeping the flue corridors warm; install several stoves in the basement and arrange them evenly, avoiding concentration of heating in one area so that heat can be distributed uniformly. Be careful though to prevent carbon monoxide poisoning – similar incidents have occurred in the past due to lack of caution, resulting in several people suffering from carbon monoxide poisoning. Increase the suction force of the flues appropriately, but not too much, to prevent excessive loss of heat from the stoves.
The suction power is low; the three-line ratio is not appropriate, and there seems to be water accumulation at the bottom
Increase the suction force and raise the temperature at the lower part, and the problem will be solved
