title: Remote temperature measurements in gas and gas-coal flames using the OH(0,0) middle-UV band.
abstract: This paper proposes and explores a technique for measuring the temperature of flames based on a ratio measurement of middle-ultraviolet emissions of OH. This method requires only a moderate-resolution mono-chromator, which should make it useful in remote sensing with a mobile facility. Initial experiments indicate the validity of this ratio method even when the flame has high visible luminosity due to the burning of pulverized coal. An empirical formula relates the theoretical ratio of two peak emissions to the temperature with good accuracy.
