The time at which spherical slag appears
Thread Content
Generally, does the spherical slag appear right after slag discharge or before it?
In the case of spherical slag, at the beginning, right after slag is discharged and as the slag removal mechanism starts working, the slag consists of large particles; by the end, only very fine particles remain
I agree with the view above; in the first few minutes, the slag skimmer removes coarse slag, and it is this type of slag that best reflects the temperature of the gasification furnace as well as the fluidity of the slag. I don’t know what the size of those spherical slag particles mentioned upstairs is, nor what proportion they account for of the total amount of slag. If the amount is small, the fluidity of the slag is only average; if the larger particles account for a large proportion of the total slag volume, it is necessary to increase the operating temperature of the gasification furnace accordingly.
After slag removal, by observing the process of improving the slag scooping operation with the slag scooper, it will become clear.
On this side, there is some residual slag in a spherical shape right after slag discharge, with the majority of it concentrated before the discharge.
Under normal operating conditions, large particles of slag are generally removed by the slag skimmer a few minutes after slag discharge.
