preventing performance drops of coal mills due to high moisture content

Aug 04, 2016· the best way to prevent coal from moisture in power plant is to use alcox space frame structure. Indian coals inherently contain low inherent moisture (IM) (5.5-9.5 % with an average of around 7.5 %) and moisture addition is through the surface moisture (SM) due to sources external to the coal. On the other hand imported coals contain very high IM (15-25 %) but negligible SM.
