http://www.aspacc2024.org/images/files/11853.pdf WebTo quantify the recirculation of combustion products, a recirculation ratio was calculated. Similar to the procedure adopted by Melo et al., (17) the recirculation ratio R is defined by eq 7 , in which A is the area of the surface shown in Figure 10 .
WebJun 13, 2024 · Flameless combustion is an emerging technology to control NO x emission via flue-gas internal recirculation and delayed mixing of fuel and oxidant. The enhanced recirculation of flue gas and low reaction speed owing to delayed mixing of reactants as well as dilution with flue gas make whole volumetric area of a furnace to participate in a …
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. chinese church perry floridaWebIn this study, the flameless combustion was stabilized when the thermal input is 21.5 kW and the maximum ratio of reactant dilution is 3.2 with low emissions using the combustor.
