Stability of furnace operation in winter
Thread Content
Our factory is located in the north, where there are large temperature differences between day and night in winter. Therefore, we have implemented different control standards for industrial processes during nighttime and during the day, and the results have been significant.
Could you tell me how you control it? Thank you!
Under normal circumstances, during winter and summer, changes in air temperature and humidity lead to significant differences in the air intake volume during the blowing phase, which in turn results in an increase in coal consumption. The specific reasons are as follows: (1) In winter, especially at night, when the air temperature drops, the specific volume of the air decreases. With the total volume of the fan remaining unchanged, the absolute mass of the air increases considerably compared to hot weather； (2) At low temperatures, the humidity of the surrounding air decreases significantly, which in turn increases the oxygen content in the air. With the same volume of gas being introduced, the effective components of the blown air increase ； Taking all the above factors into account, it is easy to see that in order to maintain stable furnace conditions and reduce coal consumption in winter, it is first necessary to shorten the blowing time. Those who pay attention can easily calculate the amount by which the blowing time should be reduced, based on the local temperature differences and humidity levels 1
