摘要：

This paper examines the possibility that the dispersants used in the preparation of coal-water slurries contribute to agglomeration during combustion. Particle size distribution measurements and SEM photographs were used to compare the agglomeration behaviour of subbituminous micronized coal-water slurries with and without dispersant. The measurements indicate that dispersants can provide a mechanism for binding agglomerates together.
