How to deal with the continuous increase in bottom pressure in a boiling furnace
Thread Content
It won’t work after just a couple of months of use – the vents get clogged. What’s the reason for that?
Our company is the same; we can’t find the reason.

A solution is to adjust the size of the air cap opening, which can help reduce scarring; however, the slag in the air chamber must be removed regularly； Normally, the furnace temperature should not be set too high, especially when the furnace is shut down as its temperature is then relatively high ； For each cold boiling experiment, it is necessary to observe carefully to see if there are areas where no boiling occurs and where scarring is more severe ； The particle size of the ore also has an impact.
An increase in bottom pressure allows some of the coarse slag to be discharged through the cold ash outlet, thereby reducing the density of the material in the boiling layer
The reason why the bottom pressure of the furnace always increases is that the holes in the air cap gradually become smaller after the furnace is started up. I don’t know what causes the small holes in the wind cap to shrink
Regarding the wind issue, the fixed layer is thin, and there are wind cap holes in the raw material paste. Analyzing this layer shows high levels of sulfur and iron
What is the lead content? What’s the temperature? Which side to block? The information is incomplete, so it’s not possible to explain the reason
A common problem with many request posts is that the issue is urgent yet few details are provided, just like when asking for integrals, where there are infinite solutions; P
Based on years of production experience, if the bottom pressure of the furnace is within the designed range under normal conditions but suddenly becomes abnormal, it is necessary to start by checking the raw materials to see whether their particle size and moisture content are within acceptable limits. If everything is normal, then the fan and air nozzles should be inspected; by proceeding step by step in this manner, the cause can always be identified. . . In short, bottom pressure is related to many factors; each case needs to be analyzed on its own
These problems are easy to solve!
