No.33 亜瀝青炭・瀝青炭混炭時の粉砕挙動2(燃焼,粉砕)

抄録

Subbituminous coal and bituminous coal were blended, and their pulverization behaviors were investigated with HGI mill. The objective of this study is to predict pulverization behaviors such as mill consumption, the size distribution of pulverized coal at mill outlet, and so forth based on the aspects of each individual coal. When subbituminous coal and bituminous coal were blended at equal rate, the pulverization behaviors of the blended coal were more greatly influenced by subbituminous coal.
