However, in the calciner, the calorific value of the fuels can be lower with the result that even CV fractions with a minimum of 2,500 kcal/kg can be used. Most significant is a homogenous grain size. From a technical standpoint, the design principles used by suppliers of calciners and other equipment are similar or comparable.

Designed to provide an efficient means for continuously processing granular materials and powders at high temperatures in oxidizing, inert or reducing environments, rotary calciner consists of a cylindrical rotating tube housed in a refractory-lined gas or electric furnace, positively sealed to prevent air infiltration. Because the bed of material is constantly being turned over, solids-to-gas ...

fluidized bed calciners and crystallizers. Fluidized bed calciners An example of a fluidized bed calciner is the Dorr-Oliver Fluo-Solids lime-mud reburning calciner (Moran and Wall, 1965). It consists of a bed of heated particles, kept fluidized by air. The bed is kept at 1,500°F (816OC) by in-bed combustion of fuel.

Used to heat materials that are fine and dusty, sensitive to oxidation, combustible, explosive, potentially contaminating or thermally sensitive, rotary calciners isolate the materials to be processed in a high-temperature chamber. The calciner's indirect-heat-source design ensures complete separation between the heat source and the product during processing.
