In this section, we focus on dry-process kilns, as they represent the majority of kilns now in use. The refracto-ry requirements of wet- and semi-dry process kilns are essentially similar after the inlet stage. 2. Kiln Fuel effi ciency and waste fuels Today's kilns have shorter lengths without loss of production capacity.

Direct-fired rotary kilns offer efficient processing for high temperature applications. A direct-fired rotary kiln heats material by passing the combustion gases through the rotary kiln. The combustion can either occur in a com-bustion chamber if direct flame radiation is to be avoided, or the flame can be directed down the length of the rotary ...

data, along with the kiln monitoring equipment, will determine the amount of refractory needed for an outage along with the areas believed to be in need of repair. Once the shutdown begins, the kiln needs a cooling down period of 18 to 30 hours. Cool down time varies with kiln diameters, amount of coating, draft control, and kiln length.
