Abstract |
On-stack instrumentation and methodology were developed to monitor the opacity of particulate pollutants in stationary source emissions containing condensed water. The instrument continuously extracts and measures the opacity of representative samples of particulate effluent. It discriminates between pollutant particles and condensed water by increasing the temperature of the sample and vaporizing the condensed moisture. The opacity of the remaining particles is measured with any commercially available high precision optical transmissometer. The instrument was successfully field tested on (1) the effluent from a furnace of an expended perlite manufacturing plant and (2) the effluent from a wet scrubber of a sludge incinerator. For particulate emissions containing no condensed water, opacity results measured by the new instrument compared favorably with results measured by a conventional across-stack transmissometer monitor. |
