Review: Burning Refuse-Derived Fuel in a Rotary Cement Kiln
1993-2-1 In cement kilns, combustion takes place under very high flame temperatures and relatively long residence times. These conditions are favourable for the burning of refuse waste. The purpose of this note is to review the combustion and pollutant emission implications of using such a fuel as a supplementary source of heat in a cement kiln.

The Material In The Rotary Kiln Movement And Residence
Rotary Kiln An Overview Sciencedirect Topics. Material residence time in the rotary kiln of a precalciner process is typically 30 minutes. The clinker exits the rotary kiln at ~ 1200 C and is cooled to ~ 60 C in the cooler before going to storage and then being ground with gypsum (calcium sulfate) to produce cement.
