How can I reduce the pressure at the fire viewing hole?
Thread Content
Our coke ovens are of the TJL43-50D type – they feature bottom injection, single heating zone, dual flues, and side loading for tamping. At present, the pressure at the observation holes of these ovens is quite high; it measures over 20 Pa each time it’s measured. What can be done to effectively reduce this pressure at the observation holes?
Adjust the air cover plate and ceiling suction force
Increase the flue suction and adjust the roof storage suction.
The best approach is to adjust the flue suction; simply reducing the flue suction will do
Reducing the pressure at the viewing hole should mean increasing the suction in the flue, right? How is it said that it’s a reduction upstairs?
The increase in the suction force of the side flues also depends on the circumstances; it is necessary to first increase the suction force of the side flues and then adjust the top suction force. Only in this way can consistency throughout the entire furnace be achieved
Thank you all. We just adjusted the suction force at the top reservoir a couple of days ago, and now the vacuum pressure in the furnace is much better.
Increasing suction can reduce the pressure at the sight glass
