Figure 3 shows the relative flow balance of six coal pipes of a mill and the comparison to Rotorprobe sampling. The conduits A1 to A3 are serving a lower burner row from left to right and the remaining conduits an upper burner row. The coal flow distribution varies between 13 and 20 per cent. The ideal value is 16.7 per cent of the total flow.
ASTM D197-87 [9]. The quantity of coal passing each sieve is used to determine coal particle sizing. The fineness was determined by sieving through ASTM 50, 100 and 200 Meshes and plot into Rosin-Rammler distribution. The sampling activities and fineness test to investigate coal flow distribution are shown in Figure 1-3. Figure 1: PC pipes velocity
