What factors can cause an increase in ash and char in coal pulverization pressurized gasification? ......Dry slag discharge; too high a grate speed can lead to an increase in residual carbon in the ash and slag ； With liquid slag discharge, changes in ash content can lead to an increase in the residual carbon in the slag. With these two slag discharge methods, large fluctuations in load and changes in coal quality can both lead to an increase in ash and residue carbon content. Of course, there’s also the stove operator.
Check your oxygen levels. . . . . . . . .
The ash bed is below normal levels, and the coal does not have enough time to react； There is channeling flow inside the furnace, along with a skewed flame layer ； Leak in the jacket ； Uneven distribution of the gasifying agent ； A higher oxygen-to-gas ratio results in a higher ash melting point.
