Applicability of Transmissometers to Opacity Measurement of Emissions, Oil-Fired Power and Portland Cement Plants

摘要

In-stack transmissometers were evaluated for their capability to monitor the opacity of smoke-stack plumes emitted by certain sources. In-stack transmissometers were installed on three portland cement plants and three oil-fired power plants. Tests were conducted to determine their performance in four areas: the adequacy of the U.S. Environmental Protection Agency-promulgated transmissometer design and performance specifications for the sources, the correlation between the opacity of the emissions measured in the plumes and in the stacks of the sources, as well as the existence of a functional relationship between the transmissometer-measured opacity and mass concentration of the particulate emission.
