Abstract

A "chemical" flame height has been defined from the ratio of CO to CO2 yields, yCO/yCO2, and has been shown to be functionally identical with previous results based on flame luminosity. The chemical flame heights have been determined for propane and acetylene data for fire Froude numbers, Q*, ranging from 0.1 to 60,000. The functional dependence of Zf/D on Q* was found to be in excellent agreement with previous luminous flame height correlations. It was thus concluded that the present methodology can be used to accurately quantify the luminous flame height for well-ventilated diffusion flames of surface fires.
