motivates the study of the transient behaviour of lime kilns, to better understand fluctuations of the bed temperature. A detailed heat transfer model of a dry rotary lime kiln is developed, including the modelling of the calcination reaction, to determine where calcination starts in the kiln, as well as the degree of calcination of the output ...
by the use of lime. The choice of the lime kiln is of paramount importance to a lime producer. It must be suitable for burning the selected feed-stone and for producing the required quality of quicklime. Several different types of kilns are used for the calcination process. These kilns can be rotary kilns or shaft kilns.
gas, wall and bed throughout the kiln, the location of calcination in the kiln, and the lime availability throughout the kiln. 2. Material and Methods 2.1. Gas Model The gas model is based on the following assumptions: • The kiln is 2D axisymmetric around the kiln centerline, and so the effects of gravity and buoyancy are neglected;

Operation: The limestone is fed into the upper shaft of the double beam kiln and descends through the shafts due to gravity. Heat is supplied by burners located in each combustion chamber, promoting the calcination of the limestone. The horizontal beam connecting the shafts provides structural support and stability to the kiln.
Vertical Shaft Kilns. Lime shaft kilns are stationary vertical kilns where the raw limestone enters at the top and gravity flows through three thermally zoned sections known as the preheating, calcining, and cooling zones. The process heats the limestone from ambient temperature to 900°C, which is the point where the carbon dioxide is driven ...
