Description Pulverization is currently the favored method of preparing coal for burning. Mechanically pulverizing coal into a fine powder enables it to be burned like a gas, thus allowing more efficient combustion. Transported by an air or an air/gas mixture, pulverized coal can be introduced directly into the boiler for combustion.

Answer: There may be a lubrication problem. Gravity forces grease to flow down through the bearing, and leaks out of the arrangement. In vertical applications, grease with a higher consistency (, NLGI 3) may be preferred to better retain the grease in the bearing. Due to the possible upward pumping effect of the bearing itself, grease with ...
