Cement Kilns: Suspension preheater kilns

In order to avoid extra handling of the dust, dry process kiln cyclones were arranged above the kiln cold end, so that captured dust could be returned to the kiln by gravity alone. It was noticed that, if part of the rawmix entering the kiln became entrained in the exhaust gas, the exhaust gas temperature was lowered, and hence energy was saved.

Challenges for refractories in rotary kilns

Surveying the non-captive lime industry reveals there are approximately 120 rotary kilns producing pebble lime in the US. Just over half these rotary kilns have stone preheaters that substantially improve their fuel efficiency. Rotary pebble lime kilns typically have four refractory zones: charging, calcining, burning, and discharge.
