Lowering ash slagging and fouling tendency of high-alkali coal by hydrothermal pretreatment

High-alkali species in coal are notorious for causing ash slagging and fouling incidents. In this paper, four high-alkali coals were individually subject to hydrothermal pretreatment (HTP), within a batch-type autoclave at 300 °C for 1 h, and the treated coals were analyzed, along with the oxygen-co...
