    Mar 05 2002 · Almost all of these constantly change which makes it difficult to maintain constant fuel fineness and to monitor the mill maintenance condition. The ECT system can be configured to measure the fuel fineness on-line. To obtain the relevant signals two sensors are mounted in a coal pipe right after a pipe bend (Figure 7).
