Modeling of Rotary Kilns and Application to Limestone Calcination
An experimental study of the calcination of limestone has been carried out in a highly instrumented pilotscale rotary kiln. Local gas solids and wall temperatures and pct calcination have been measured under a range of operating conditions to determine the influence of limestone type feed rate rotational speed inclination angle and particle sie on calcination and heat flow in the kiln
