Flameless combustion recirculation ratio
WebFurthermore, the critical role of later parameters in the previously reported transition between conventional and flameless combustion modes for the present combustor is demonstrated. A threshold value of recirculation ratio, Kcritical, is found critical for flameless operation and is noticed to increase with increasing excess air ratio. WebJun 15, 2005 · Radiative losses from the reaction zone are larger than for conventional flames because of the high recirculation ratio of high emissivity product gases. These losses significantly reduce the combustion temperature and so the NOx.} journal = [] volume = {200501} place = {Netherlands} year = {2005} month = {Jun} }
