Field studies were conducted to obtain basic research data as a base for developing design and performance specifications for transmissometers which are to be used to measure smoke stack plume opacities. Tests, conducted on the stack of a pulverized coal-fired power plant, were designed to evaluate the influence of transmissometer illumination and light receiving angles, and transmitted light wavelength on in-stack opacity measurements and their correlation with the stack plume opacity. Two specially-designed transmissometers, one having a small fixed illumination-viewing angle design and the other having adjustable illumination and viewing angles, were mounted on a cylindrical 145-inch diameter steel stack to measure the in-stack opacity. A 0.5 deg telephotometer was used to determine the out-of-stack opacity of the plume as viewed from a distant river bank. The report contains a description of the transmissometers employed in the study, the experimental test program applied, and the results achieved. (Author)
