Formulation of slurries for slurry-fed coal gasifiers

A 100 MW integrated gasification/combined cycle generating plant was recently put into operation at the Cool Water generating station of Southern California Edison Co. Coal is fed into the gasifier as a coal water slurry. This paper reports on a study on the slurryability of candidate gasifier coals and slurry formulation options for use in systems of this type. The ten candidate coals studied ranged in equilibrium moisture from 1 to 13%. A...
