Thermopower Furnaces is a specialist of custom designed rotary kilns. Rotary kilns are typically run at significantly higher temperatures when compared to rotary dryers. Rotary Kilns drive a physical or chemical change to the processed material which may require either oxidizing, reducing or inert gas atmospheres within the rotary tube.

In KilnSimu the rotary kiln is divided into number of axial calculation zones, in which the radial temperatures of material bed and gas fl ows and inner and outer wall of the kiln are assumed constant. The volume elements of material bed and gas in the zones are described as open thermodynamic systems, which transform mass and heat with each …
