Fuels In Rotary Kiln Burner Www Mytechmouse Com

Apr 14, 2006 Abstract Various types of alternative fuels can be used in rotary kilns depending on the local supply availability, and each one has a specific influence on the flame pattern. Low calorific value waste fuels must be limited to a small portion of the total heat release as they tend to lower flame temperature, but a compromise can be reached when firing high and low calorific value alternative ...
