Figures & data
FIG. 1 Sketch of the cyclone, designed for a cutoff point of approximately 25 μ m at a flow rate of 30 l/min.
FIG. 2 Scheme of the porous tube diluter (PTD) sampling probe.
FIG. 3 Scheme of the measurement setup with PTD probe.
FIG. 4 The setup of the sampling line subsequent to the probe (without isolation) with a sketch of the isokinetic divider separating the sample flow for ELPI/BLPI and APS.
FIG. 5 Cross section of the MSI boiler investigated.
FIG. 6 Total mass concentration of the particulate matter of the raw gas of each of the four passes, yielded by adding all measured data and loss processes (all figures standardized to NTP conditions).
FIG. 7 Chemical composition of all size fractions (in micrometers) of 1st (left) and 3rd pass (right). Columns 1–8 shows the composition of the BLPI cascade, column 9 the composition of the inlet and columns 10–15 the composition of the sieved fractions of the cyclone. The so-called “Rest” is the sum of present minor elements (like titanium, bromine, etc.) and the oxygen of the oxides of the shown elements.
FIG. 8 Mean size fractionated mass concentration distribution of all 4 passes (all figures standardized to NTP conditions).
FIG. 9 Time resolved measurement of particle mass concentration during soot blowing routine. The reciprocating movement of the 2nd and 3rd soot blower produces two maxima each.
