Flameless combustion recirculation ratio
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 . WebRecently, flameless combustion has been developed as an innovative combustion method to intensify combustion performance and to decrease the pollutant formation contemporaneously. The outstanding economic aspects and merits of flameless combustion have persuaded the combustion scientists to investigate about this unique …
