Turbulent-flow characterization and radiation from gaseous fuel jets. final report, April 1985-October 1987
Methods for increasing and predicting the radiant output from turbulent-diffusion flames were studied in order to improve the design and increase the efficiency of industrial gas burners and furnaces. The effects of the thermochemical parameters (i.e. additives, preheating) and the flow field, which both affect flame radiation in turbulent flames, were investigated by measuring smoke-point heights in laminar flames, and correlating these measurements with the radiant-fraction measurements in turbulent diffusion flames over a range covering buoyant to momentum-driven flows. After investigating several additives and preheating conditions, it was found that fuel preheating is the most-promising method to increase soot and flame radiation in natural gas (methane) flames, while keeping nitrogen oxides at low levels.
