Drying of Coal by a Solid Heat-Transfer Medium

Drying of Coal by a Solid Heat-Transfer Medium

The VNIIMT tested a coal drying method based on a solid heat-transfer medium (for example, metal balls). This method considerably speeds up the drying process due to the large heat-transfer area between the solid medium and the small particles. This reduces the length of the drum dryer to one-half o...

Zusammenfassung:The VNIIMT tested a coal drying method based on a solid heat-transfer medium (for example, metal balls). This method considerably speeds up the drying process due to the large heat-transfer area between the solid medium and the small particles. This reduces the length of the drum dryer to one-half or even one-third of the original length and specific heat consumption.
