✦ Synopsis
15 Environment (pollution, health protection, safety) flame near the burner exit tends to keep the temperature at a high level in the region between the two flames. With the flame tip opening, the temperature in this region decreases. The above flame structure has an important effect on the pollutant emission characteristics from these flames. The NO, emission index (EINO,) continues to increase gradually for overall equivalence ratio starting from I .5 up to IO. The CO emission index (EICO), on the other hand, remains nearly constant with respect to the variations in the equivalence ratio, and shows a substantial difference depending on the mixing characteristics of the fuel with the main premixed stream.
