Rotary kilns are widely used in industry to achieve effective gas−solid heat transfer at high temperatures by direct contact with hot flue gases obtained by combustion. However, various disturbances related to nonpremixed combustion often used in practice introduces undesired variability in product quality and forces overheating, especially when obtaining the desired quality is dependent ...

· In the rotary kilns particles are fed at the upstream end and are discharged from the downstream end. The feed materials are heated in a rotary kiln by hot gases or flame introduced into the kiln from the downstream end. Particles are filled typically 5 15 % of its volume. Higher filling reduces mixing efficiency.

The aim is to develop a kiln burner with the capability to reach the maximum burner momentum at any flame shape, not only in one single point as with two primary air channel (or nozzle) burners. The burner momentum is the power available to the kiln operator to control the combustion process in the rotary kiln.

Rotary Kilns. Most rotary kilns are direct fired with a flame shooting into the kiln from the discharge end (the fire wall) As the kiln rotates, the heated material climbs the kiln wall before flopping down and flipping over With each flop, the material travels a short distance along the length of the kiln.
