How to deal with high channel temperature and machine focus temperature difference
The temperature of the branch flue is too high, which may be caused by the downdraft regenerator leaking into the gas combustion. The brick gas duct can be shotcreted. In addition, the machine coke temperature difference may also be caused by this reason.
Agree with the opinion above, you can measure the temperature of the exhaust gas when the exhaust panel is in downward airflow, and check the leakage locations one by one.
You can consider appropriately closing the exhaust gas flap to reduce the temperature of the branch flue.
Measure the air excess coefficient at the fire hole and exhaust gas pan, compare them, and then check whether it is a cross-leakage or a large gas volume, and then adjust it according to the suction.
If the temperature is not too high, then there is a cross leakage in the regenerator.
6# Cold extreme cold If the standard temperature is reasonably set and the straight-line temperature is not much different from the standard temperature, you can consider 1. The suction on the coke side is too large, resulting in a small flue and the temperature of the separate flue increases. 2. Large-scale cross-leakage and fire can cause high temperatures in the regenerator and even burn out the checker bricks. Measures such as strengthening the sealing, such as spraying, grouting the brick and coal air ducts, etc.
