Lime Kiln - an overview | ScienceDirect Topics
For most operations except for dead burnt dolomite, the burner tip velocities can range between a low of 25 m/s and a high of about 60 m/s. These are significantly lower than the velocities of cement kilns, which operate around 80–100 m/s. The momentum ratio and associated Craya–Curtet parameter is usually lower than 2, which means that the ...
