Coal Drying Improves Performance and Reduces Emissions
In summary, the analysis shows that a substantial improvementin unit performance is possible by removing a portion of the coal moisture. This performance improvement is primarily due to a reduction in moisture evaporation loss, lower stack loss, and a decrease in auxiliary power requirements. The mass emission rate of pollutants such as SO 2
Mill Inerting Systems Presentation to the ASBCUG
Jun 07, 2018 · High volatile matter and highly reactive coals encourage pre-ignition inside the mill. Higher moisture content requires temperature extremes inside the mill. High moisture, high volatile matter and highly reactive coals are prone to self heating and can spontaneously ignite due to rewetting. Rehydration is exothermic and dried coal that is ...
