•White Paper: Validation Study Of FTIR-Based Emissions Measurements At A Municipal Waste Combustor
Abstract
EPA Test Methods 301 and 320 include statistical techniques for validating sampling methods in specific gas matrices. Several of these techniques were used to analyze extractive FTIR data collected at a municipal solid waste incinerator and to validate the method for hydrogen chloride (HCl) measurements. FTIR results for carbon monoxide (CO), sulfur dioxide (SO2), and nitric oxide (NO) were also compared to measurements recorded by the facility's continuous emissions monitors (CEMs). Presented are discussions of the equipment, spectral analyses, and statistical comparisons of the various test methods.
Introduction
The work described here was performed in October, 2004, at two sampling locations of a municipal waste combustor. The major goal of the study was to validate extractive Fourier transform infrared (FTIR) spectrometry for measurements of gaseous hydrogen chloride (HCl) as described in Environmental Protection Agency (EPA) Test Methods 301 and 320.Three different validation procedures were successfully performed; they were direct comparisons with EPA's ‘manual' Test Method 26, "single instrument" dynamic spiking, and "dual instruments" dynamic spiking.
