Effect of in-Situ Heat Treatment on Coal Char Reactivity. Part 2. Temperature Measurement in Flames. Progress Report, January 1-March 31, 1985

摘要

Four methods of measuring temperatures in pulverized coal flames are being investigated or developed: (1) the suction pyrometer, which is thought to measure a weighted average of the gas and particle temperatures; (2) two-color pyrometer, primarily to measure the particle temperatures; (3) sodium line-reversal, primarily to measure the gas temperature; and (4) OH peak method in the uv, as a new alternative to sodium line-reversal which may be superior for measuring gas temperatures in the presence of particles. This report describes progress, mainly on development of the first two techniques, and plans now being implemented for development of the last two. 4 refs., 12 figs., 2 tabs. (ERA citation 10:029724)
