Question: What causes the high bottom temperature of a gas stove? How to avoid and deal with it?
If it is a Luchi furnace, with a high furnace temperature, it might be due to a high grate speed and a lower fire layer; adjust the grate speed and load

1. Is the steam volume too low?； 2. Gray layer decreases, oxide layer decreases ； 3. Is the ratio of air volume to coal volume appropriate?
1. Damage to the bottom furnace bricks or grates. 2. Excessive central oxygen causing the flame to stretch. 3. Is the slag outlet blocked?
Question: What causes the high bottom temperature of a gas stove? How to avoid and deal with it? High temperature, locally? The whole thing? Locally, it should be brick peeling in that area. Make appropriate and substantial changes to the load, and rearrange the ash and slag distribution ； If nothing else works, the only option is to stop the vehicle. Overall, it might be due to thinner bricks, changes in the flow within the furnace (the fire zone moving downward), load issues, operating temperature problems, or blockages at the slag outlet. . . The methods mainly involve changing the temperature and load, or adding oxygen to raise the temperature; for situations that cannot be handled through operations, the plant has to be shut down.
I haven’t been working in this field for long. What does it mean by whether the ratio of air volume to coal amount is appropriate?
This is a fixed-bed batch gas furnace; the temperature on the downward side is high, while the temperature on the upward side is normal. Why. How to handle it?
I have a 2.4-meter two-stage gas stove. What should I do if the temperature during inspection on day 7 is too high?
First, the ash layer is thin, allowing for a slight reduction in the speed of the furnace rods. Second, the ratio of steam used for upward and downward blowing is imbalanced, and this can be adjusted accordingly.
