This test was part of a program to investigate the quantity and type of aerosol sulfates emitted from Western low-rank coal-fired utility boilers with flue gas desulfurization systems. The average particulate removal efficiency of the module tested was 38%, as calculated from the instack filter results for 10, 11, and 12 June. The impactor total mass loading results are in fair agreement with those measured with the instack filters. The size dependent particulate removal by the scrubber may be characterized by the size at 50% collection efficiency, or cut point of the scrubber. The cut point is about 1.2 micrometers physical diameter. The average SO/sub 2/ removal efficiency of Module All, based on the continuous monitor results, was 91%. On the average, based on the instack filter results, 40% of the particulate mass loading at the inlet is sulfate. At the outlet, this fraction was 27%. The absolute amount of sulfate is roughly the same at inlet and outlet.
