| Abstract: | A dilution stack sampling system was designed to measure particulate matter from stationary combustion sources. It simulates the cooling, dilution and condensation process after the hot flue gas leaves the stack and collects primary particulate matter. The special features of the sampling system are described in detail Tests ,sere also carried out to verify the sampling system. The system shows considerable stability, simple operation and credible measuring data. It was optimized to a small size for field testing. The system has been successfully utilized to characterize particulate matter from representative stationary combustion sources in the field. |
