摘要

The stability of the burner flame is critically important in lime kiln operation. It can be affected greatly if non-condensible gases (NCG) are burned in the kiln. A Flow Simulation Apparatus was used to study the mixing and interaction between a simulated main burner jet and a simulated NCG burner jet in a confined cylindrical duct. The results show that the angle of the NCG jet with respect to the duct axis is the dominant factor in determining the mixing and interaction between the two jets. The lateral expansion rate of both jets decreases with an increase in Reynolds number (Re) and in Craya-Curtet number (Ct) of the jets. The expansion of the jet is important, because it determines the shape of the flame (long or bushy), the temperature and heat transfer in the kiln, and whether the flame may impinge on the kiln walls. The results also show that the recirculation zones in the confined duct are longer with two jets than they are with a single jet. This implies that burning NCG tends to lower the temperature of the main burner.
