Slag Behavior in Gasifiers. Part I: Influence of Coal ...

In the entrained-flow gasifiers used in integrated gasification combined cycle (IGCC) plants, the majority of mineral matter transforms to liquid slag on the wall of the gasifier and flows out the bottom. However, a small fraction of the mineral matter is entrained (as fly ash) with the raw syngas out of the gasifier to downstream processing.

UP: Coal Glossary

The pulverized coal-fired wet-bottom unit traps 50% or less of the ash as molten slag on the furnace walls; this slag runs down to the furnace floor and taps down into the slag tanks for removal. Cyclone furnace boilers are the wet-bottom type because they make slag that flows out on the furnace walls, then to the floor, and into slag tanks.
