Detailed introduction

MPS Coal Mill

The information gained will include coal pipe balance, coal fineness, air/coal ratios, as well as the condition of the grinding components, mill throat, classifier, springs, and other components. This information is then provided to the Power Plant in a comprehensive report and is used as a tool to determine which modifications are required to meet their specific target or performance goals.

Flexible operation of coal

Only after this was achieved and another coal mill was connected, the backup fire was reduced or switched off. Thus, defined load conditions for sole coal operation were at 30 to 40 percent. Furthermore, at least two coal mills were common or planned for this mode of operation. Get price
