Overview of HCl Monitoring Technologies

摘要

1. Overall the HCICEMS performed very well(considering limited operating experience on coal-fired plants) 2. The HCl response from the FTIR and CRDS systems from October 2013 - January 2014 consistently followed the same trend 3. The absolute avg. difference between the Thermo FTIR and Spectrum-Tiger Optics CRDS (@1,769 hours) was ～0.1 ppmw 4. Average absolute difference between two TDL-based instruments during the same time period was ～0.4 ppmw 4.1 However, the difference between the two TDL-based instruments did drop to ～0.2 ppmw after Cemtek-Unisearch implemented their moisture correction routine in early December 2013.
