A field evaluation was conducted of the Barringer Correlation Spectrometer (COSPEC) at a pulverized coal fired power plant. The Barringer COSPEC II instrument, an SO2 remote sensor, was compared to the manual in-stack SO2 and velocity compliance tests for emission measurements. The correlation for short term (one hour or less) comparison was poor. Higher correlations for SO2 emission rates on a daily basis were found. In addition to the COSPEC II, a COSPEC III and COSPEC IV were used in the study. Correlations among the three instruments were good (90-95%). Main source of error in the remote measurements was the wind velocity determinations. For a short time span of less than an hour, wind velocity may vary 100% and only averages can be obtained for the measurements.
