Reasons for high temperature after sulfur making furnace
Thread Content
The acid gas volume remains unchanged and the air volume remains unchanged. There is no problem with the waste heat boiler. The temperature behind the furnace rises. After the condenser is filled with water, the outlet temperature of the first cooling is lower than the temperature of the second and third cooling. After the water is stopped, the temperature of the first cooling is high.
It is possible that the high-temperature blending valve is opened too wide, causing bias flow, causing most of the process gas to leak directly into the first and second revolutions, while a small amount of process gas passes through the first cooling.
We originally had the problem of blockage of the furnace tube of the waste heat boiler. When the furnace tube is blocked, this phenomenon will occur.
Are your sour gas meters accurate? I think if it is confirmed that there is no problem with the remaining pot, it should be that the acid gas has changed and the heat has increased. Has the furnace temperature changed?
