Abstract:
In this paper, effect of dispersion rate on briquet quality and different factors which influence dispersion rate of sewage sludge in fine coal were studied. The results showed that the dispersion rate of sewage sludge in fine coal depends on the ratio of fine coal/sewage and the agitating strength. It was found that the more completely sewage disperses in fine coal, the higher strength the briquet has and the less dispersion rate of briquet strength results. The higher gasification activity of briquet causes the lower carbon content in the residential ash after gasification.
