Strategies for Continuous Monitoring of Hydrogen Chloride Emissions from Municipal Solid Waste Incinerators

摘要

The paper presents a discussion of sampling and analytical techniques for continuous monitoring of hydrogen chloride (HCl) emissions from incineration sources. The discussion focuses on commercially available systems for sample conditioning and measurement. Six HCl continuous emission monitors were evaluated at a municipal facility for solid waste incineration. Field test results indicate that several techniques for continuous monitoring of HCl concentrations are available. Most of the analyzers tested, regardless of the detection or calibration techniques, indicated the same trend in the effluent HCl concentrations and produced data that was in good agreement with wet chemistry results.
