Application Note: Validation Study Of FTIR-Based Emissions Measurements At A Municipal Waste Combustor

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 (HC1) measurements. FTIR results for corbon 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.
