with fossil-fired power plants are required to use continuous emissions monitoring systems (CEMs) to measure and report quantities such as NOx and SO2 emissions.
Among its many components, the typical, most used CEM system includes a flue gas flow meter and a device referred to as a dilution extractive probe for flue gas sampling.
Numerous studies have pointed to inherent positive measurement bias errors in these devices, which can be as high as 20 percent in some cases.
Over-reporting represents the potential for financial losses associated with the NOx and SO2 emissions trading system in the U.S.
In other countries were this system is not in place, there is need for accurate reporting of stack emissions from power plants....
