ROTARY LIME KILNS Slides 1 and 2 are the title and outline for the presentation Slide 3 below shows a schematic of the exterior of a modern rotary limereburning kiln Slide 4 shows a schematic of the interior features of a limereburning kiln Rotary lime kilns are large steel tubes that are lined on the inside with refractory bricks
Heat exchange in a rotary kiln may be by conduction convection and radiation in descending order of efficiency In lowtemperature processes and in the cooler parts of long kilns lacking preheaters the kiln is often furnished with internal heat exchangers to encourage heat exchange between the
