Optimisation of coal fineness in pulverised-fuel boilers
A method for choosing the optimum fineness of coal in pulverised-fuel boilers is presented. This method is based on economic criteria and takes into account variations of the power unit load as well as the durability and the output of pulverisers. Calculations are performed for short periods of time (e.g. 1 h), provided that it is possible …

A Comparison of Three Types of Coal Pulverizers
The BTM is a low-speed mill that primarily grinds coal by impact and attrition. The VRM is a medium- speed mill that grinds coal by compression and, because of the low coal inventory in the mill and flat grinding surfaces, develops shearing action as well. For both mills a constant centrifugal force is maintained. The speed
