内容記述 | In this study, we have examined co-flowing diffusion flames formed in a triple port burner. The coannual burner consists of three concentric tubes. Air flows in both inner (central) and outer tubes, and fuel flows in the annulus between these air tubes. These velocities are defined as U1A, U2F, and U3A (or U3N), respectively. The fuel is propane. Two diffusion flames are formed in the boundary of fuel and air. For comparison, nitrogen is ejected in the outer tube to examine the mutual effect of two flames. The luminous flame height was obtained by direct photographs. A laser induced incandescence (LII) technique was applied to examine instantaneous soot concentration. To discuss the mixing of fuel and air, a NO-PLIF technique was used, where NO is added in the fuel flow. Results show that, as the fuel velocity, U2F, is increased, the flame height becomes larger. When nitrogen is ejected in the outer tube, the flame height is larger. However, the flame temperature for both cases is almost the same. The LII measurement shows that there are two soot regions in two luminous flame zones which are emerged in the downstream. The soot concentration in the inner flame is higher than that in outer flame when U1A < U3A, but it is lower when U1A > U3A. The minimum soot concentration is achieved when U1A and U3A are the same. | |||||
