Slag Behavior in Gasifiers. Part I: Influence of Coal Properties and Gasification Conditions
Energies, 2013 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.

Slagging gasification of coal under addition of flux agents
Fuel Processing Technology, 1985 Abstract Despite a general trend towards higher reaction temperatures with coal gasification processes of the second generation, process and material considerations also make it desirable to limit temperatures to a maximum of about 1500°C to 1600°C. For coal gasifiers to be operated under slagging conditions this means that feed coals with high ash ...
