REGULATORY CONTROL OF A PILOT ROTARY KILN FOR

2006-1-1  INTRODUCTION The rotary kiln is the main process equipment in the activated carbon production by means of physical activation of charcoal with water vapor. In the last time, a complete study about the operation of a pilot rotary kiln for such process has been performed in our laboratory (Ortiz et al., 2003a, b; Ortiz et al., 2005).

2012-9-27  The direct-heated rotary kiln is broadly used for physi-cal activation. The pilot rotary kiln is a cylinder that rotates around its longitudinal axis and essentially oper-ates as a heat exchanger (Ortiz et al., 2003a). It has a diameter of 0.30 m with 3.70 m length and is covered with 0.15 m of insulation material. The cylinder is

Rotary Calciners - FEECO International Inc.

Rotary Calciners. Rotary calciners, also commonly called indirect kilns, are used in various calcination operations where exhaust gases must be minimized, when processing finely divided solids, or where temperature must be tightly controlled along the length of the kiln.. A calciner is comprised of a rotating drum inside a furnace, which is externally heated.
