Problems on the coke side of the coke oven heating machine?
Thread Content
The expansion on the coke side of the coke oven heating machine varies; in a 6 M coke oven, the temperature has reached 350 degrees, yet the expansion on the coke side differs by 10 MM. What causes this? What harm can it cause to the furnace body? What should be noted?
Whether the machine side is larger or the furnace side is larger, as well as the load on the gas collection pipes and riser pipes on the machine side furnace column, all these factors affect the degree of expansion on the machine side.
Could you be more specific? What is the grade? What are the standard flame temperature and managed flame temperature for the gas and coke sides, as well as the temperature ratios for the regenerator and the small flue? But 10mm should be fine; it’s already at 350 degrees. Furnace No. 3 in our plant has reached 360 degrees today.
It’s quite large; I compared the data from our factory (the maximum difference for lines 1, 2, and 4 on the machine-side is 4 millimeters). You need to improve temperature control.
OP, your question is a bit too broad. The reasons for this situation could be as follows: 1. Uneven heating on the machine focus side leads to uneven expansion. 2. It’s possible that the platform on the machine focus side does not slide properly during the baking process, resulting in uneven stress on the steel columns and affecting expansion. 3. Errors may occur due to inaccurate positioning at the beginning of the baking process. It is recommended that the poster improve furnace temperature control and flame adjustment, as well as manage the measurement personnel.
Temperature rise management should be strengthened to ensure a steady increase in temperature and prevent fluctuations, as otherwise it has a significant impact on the furnace.
The uneven heating on the machine and furnace sides leads to uneven expansion; it is possible that the platform on those sides does not slide properly during the baking process, resulting in uneven stress on the steel columns and affecting their expansion.
