Results from this testing illustrates large fineness deviations from pipe to pipe. Non Iso-kinetic testing or not sampling all fuel lines can lead to unrepresentative results. All coal pipes from a single pulverizer will usually have varied fuel fineness. Sometimes, widely varied. Testing all pipes is recommended.

In another plant, as-found test data show that coal pipe flow far exceeded the recommended ±10% deviation limit and that there was high variability in coal fineness. Source: Storm Technologies ...

86 MILL DIRTY AIR FLOW TEST 861 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 daytoday basis mill performance is monitored.

Collecting coal samples using an isokinetic probe provides the best data describing actual operating conditions inside the coal pipe. Source: Storm Technologies Inc. The isokinetic coal sampling method, although more difficult, is the best option for determining the true mill coal fineness produced and to calculate pulverizer performance.

The first phase of this program should include a complete Mill inspection and accurate coal pipe testing which will establish baseline data. 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.
