The breakage characteristics of low rank coals were tested in a laboratory using ECO coal from an Indonesian mine as the feed material. The grinding test results were used to fit the parameters of the breakage functions of an existing continuous hammer mill model. The mill hold-up, specific energy and projection rate to the screen were analyzed to observe the effects of operating conditions. The results...
The Coal-Direct Chemical Looping (CDCL) process using iron-based oxygen carriers has been developed as a coal conversion process with in situ CO 2 capture. The CDCL system cycles oxygen carriers between two reactors, a reducer reactor and a combustor reactor, in order to convert coal for electric power generation. The reducer reactor features a unique design of a gas–solid counter-current...
