An Examination of Bias in Method 2 Measurements Under Controlled Non-Axial Flow Conditions

摘要

Since the installation of continuous emissions monitoring systems (CEMS) under the Acid Rain Rule (40 CFR Part 75), many utilities have found that CEMS are recording consistently higher heat input and SO_2 emissions than conventional methods (input/output and output/loss). This discrepancy, which appears prevalent across the industry, is causing utilities to report greater heatinputand SO_2 and CO_2 emissions than are believed to be justified.
