立炉による石炭灰を原料とする軽量骨材製造プロセスの開発 (第2報)
Calcination tests of a pellet made of coal ash were performed in order to obtain the data for design and operation of a mov ing bed shaft kiln. Factors controlling calcination process in a fixed bed are found to be gas flow rate, Gg, oxygen concentra tion of gas, yo20, as well as carbon content of the pellet, xc. From the theoretical consideration on calcination in the fixed bed, the fixed bed behavior can be characterized by the rate, v, of travel of the position where a bed has a maximum
