Survey of Particulate Emission Macro- and Micro-Sampling and Sizing Methods and Real-Time Monitoring and Sizing Methods

摘要

A survey was conducted of recently developed methods for sampling and fractionating flue gas particulates. The survey was composed of three parts: (1) macro methods - sampling/fractionating equipment capable of collecting in each of several particle size cuts, macroscopic samples appropriate for subsequent chemical and physical characterization, (2) micro methods - size-fractionated particulates for microanalysis and (3) real time-monitoring/sizing methods permitting real-time acquisition of particle size data via remote or point-of-measurement techniques. Results presented include a survey and cursory evaluation of commercially available macro, micro, and real time measurement systems. Also, research and development efforts underway in the commercial, academic, and governmental sectors were identified and delineated, where possible, with respect to primary researcher(s), affiliation, program objectives, schedule and sponsoring agency where applicalble. The study concludes that macro and micro methods utilizing impactors and cyclones are available, but reliable only with careful and proper operation. In contrast, real-time source monitoring of particle size is, with few exceptions, still in a developmental stage and very expensive. (ERA citation 06:033742)
