Influences of different comminution methods on maceral segregations, ignition, and pyrolysis of superfine pulverized coal

Yang Ma, Jiaxun Liu, Yuanzhen Jiang, Xiumin Jiang

Abstract

The same bituminous coal is grinded by three representative grinding systems, respectively. Tendencies of maceral segregations in three systems are analyzed. The influences of maceral segregations on ignition temperatures and flash pyrolysis products are compared and discussed.
