Rotary Kiln Incinerator Meaning Cas Lab

Experimental And Numerical

A

A comprehensive study of rotary kiln incineration is ongoing at louisiana state university. through experimentation at all levels and numerical modeling, the underlying physical processes are searched out and studied with the intent to improve the understanding of how rotary kiln incinerators.A rotary-kiln incinerator is a refractory-lined cylindrical shell mounted at a slight angle to the horizontal, as shown in figure 1. the kiln is rotated about its longitudinal axis and the solid waste is fed into the upper end of the cylinder. waste combustion occurs as the material moves to the lower end of the cylinder where ash is.
