Optimum Air Feed Locations on Medical Waste Incineration

This serves a volume reduction of 75 to 95 percent of the total waste volume [3]. Heat distribution is a critical part of the incineration operation. There are several studies on the evaluation of the heat distribution in a furnace [6-8]. This study was conducted in order to i) investigate the current state of a medical waste rotary kiln that is being operated, ii) investigate the effect of

Cement Kilns: Design features of rotary kilns

The rotation of the kiln lifts the feed up the side of the kiln, and the energy required to maintain its centre of gravity above the lowest (6 o'clock) point is the main component (80-90%) of the energy consumed. In the case of kilns containing curtain chains, these also produce an eccentric load. Rotary kilns have always had variable speed drives.
