    Power Requirements for Ultrafine Grinding and Drying of ...

    An experimental evaluation of the power requirements for simultaneous ultrafine grinding and drying of lowrank coals in a fluidenergy mill was undertaken. Two different lignites and a subbituminous coal were used in the study. Ultrafine grinding tests were conducted with air nominally at ambient conditions and with steam at temperatures ranging from 225°F to 488°F. It was found that the ...

    Coal Drying Improves Performance and Reduces Emissions

    coal drying equipment and impact of fuel moisture on plant performance and emissions are discussed. The improvement in boiler and unit performance, achieved during the test by removing 6 percent of fuel moisture was in the to percent range. This performance improvement is primarily due to a reduction in moisture evaporation loss, lower stack loss, and a decrease in auxiliary power ...

    The paper presents a basic model of the flash drying process, as it is applied in a number of industrial appliions, and illustrates this by means of a particular appliion: the drying of subbituminous coal. Besides its economic importance, that appliion is representative of those where the product is combustible, so that the drying needs to be conducted in an inert atmosphere, which is ...
