Validation of a New Method for In-stack Measurement of Particulate Matter Emissions from Large Stationary Sources

Abstract

A new method for measuring particulate matter in stationary sources has been developed by Rupprecht & Patashnick Co. (R&P). This new method, named the TEOM® Series 7000 Source Particulate Monitor, uses R&P TEOM technology to provide in situ, filterbased, direct mass measurement of particulate matter in stationary source emissions. The performance of this new monitoring method has been quantified in accordance with U.S. EPA Method 301 by making simultaneous collocated measurements with paired Series 7000 and paired EPA Reference Method 17 sample trains. R&P, with the assistance of staff from the Greater Vancouver Regional Department, Vancouver, B.C., Canada, conducted a series of tests at a coal-fired cement plant to evaluate the performance of the Series 7000. The paired Series 7000 sample trains were configured identically using the on-board Series 7000 software configuration routines and operated in accordance with standard test procedures developed by R&P. The paired manual sample trains were configured and operated in accordance with U.S. EPA Reference Method 17. Each test was made for a duration of at least one hour to ensure sufficient particulate matter was captured on the manual sample train filters. Average particulate matter mass concentrations were determined for each sampling train and used for a statistical analysis of precision and bias per U.S. EPA Reference Method 301. For each test run, the average mass concentration results for each sample train are tabulated and have been presented along with the results of the statistical analysis to determine the bias and precision for the new Series 7000 method.

Introduction

A new method for measuring particulate matter in stationary sources has been developed by Rupprecht & Patashnick Co (R&P). This new method, named the TEOM® Series 7000 Source Particulate Monitor, uses R&P TEOM technology to provide in situ, filterbased, direct mass measurement of particulate matter in stationary source emissions. The engineering design of the Series 7000 incorporates features to automate isokinetic sampling and analysis of particulate matter mass for applications such as compliance testing, process/control system optimization and calibration/certification of particulate matter continuous emissions monitoring systems. This new method has been designed for use in fixed installations or as a portable system for use at many different sources. To assess the performance of this new monitoring method, R&P, with the assistance of Air Division staff from the Greater Vancouver Regional Department, conducted a series of tests at a coal-fired cement plant in Vancouver, British Columbia during July 2000. The performance assessment was quantified in accordance with U.S. EPA Method 301¹ by making simultaneous collocated measurements with paired Series 7000 and paired U.S. EPA Reference Method 17¹ sample trains.
