Mill Dirty Air Flow Ch-8.6 - wbpdclewf

8.6 MILL DIRTY AIR FLOW TEST 8.6.1 Intoduction The factors affecting pulveriser performance include grindability of coal, moisture content of coal, size of input coal, wear condition of grinding elements and classifier, fineness of pulverized coal, primary air quantity and temperature. On a day-to-day basis, mill performance is monitoredPulverized Coal Pipe Testing and Balancing,Dirty air test equipment.,as-found test data show that coal pipe flow far exceeded the recommended ±10%,The next step in this plant is to upgrade the mill to improve coal fineness to 75%,Measuring Coal Pipe Flow - Storm Technologies, Inc.,normal fuel flow (dirty air velocities) are at-tributed to the additional energy required to transport the heavier and denser coal stream (rope) through the heavier coal-laden fuel pipes. This is why the fuel lines are first balanced on clean air and then followed by dirty air
