Holographic Determination of Injected Limestone Distribution in Unit 10 of the Shawnee Power Plant

摘要

Pulsed ruby laser holography was applied as a technique for detecting the penetration and dispersion of limestone plumes injected into the Unit 10 boiler operating at nominal conditions. The experimental equipment, the laboratory experiments, and the test programs are described. Two-beam scattered light holography of particulate in an operating boiler (nominal power output of 140 mw) is entirely feasible. Photometric means of evaluating the reconstructed holographic images have been developed to the extent that quantitative data, as well as qualitative impressions can be obtained. (Author)
