Flame emissivities - alternative fuels
An understanding of radiative heat transfer from combustion products is needed for the prediction of thermal efficiency and heat-flux distribution in furnaces and for the estimation of the thermal punishment of the confining walls in internal combustion engines and gas turbines. The emissivities of combustion products are considered, taking into account carbon dioxide, water vapor, the overlap correction factor, soot, carbonaceous particles, the emissivities of mixtures of solids and gases, furnaces fired with low- or intermediate-Btu gas, the effect of H/C ratio on the nonluminous contribution to emissivity, the emissivity of coal combustion products, diesel engines, and gas turbines. It is found that the expected shift from petroleum-derived oils to coal-derived liquids would have only a modest effect on the nonluminous contribution to radiation in a large-scale combustor. The greatest potential impact of increases in radiation anticipated with increases in the C/H ratio of fuels is in the design of gas turbine combustors.
