Evaluation of Stationary Source Particulate Measurement Methods. Volume V. Secondary Lead Smelters.

摘要

As part of an overall program to evaluate the EPA Method 5procedure for measurement of particulate emissions,an experimental study was made of its specific applicability to secondary lead plant emissions. The study was carried out with two Method 5sampling train systems operated simultaneously at a single point in the stack emission stream. A series of six statistically designed tests was conducted over a 5-day period to obtain data on the reliability of Method 5,the sensitivity of the method to variation of such key parameters as sampling system temperature,filter media,and particulate loading and to characterize the chemical composition of the emissions. Comprehensive chemical analyses were made ofj particulates collected in the sampling system and from the baghouse control to ascertain if the sampling mode affected the composition of the particulate emissions. Essentially 100percent of the particulates were accounted for by the chemical analyses. Compositional analysis of the gaseous species present in the stack gas stream also were performed. The results of the particulate and gas analyses do not indicate any chemical interactions with the sampling system components of the Method 5train.
