The typical hazardous waste kiln is a cylinder with an outside diameter of 11 to 12 ft, an inside diameter of 8 to 9 ft, and a length of 33 to 38 ft.1 Rotary kiln incinerators are mounted with the axis at a slight incline and are usually refractory-lined. The kiln may rotate from 5 to 25 times per hour. Waste and auxiliary fuel,

waste. Waste feed capacities for excess air incinerators are usually 3.8 kg/min (500 lb/hr) or less. Rotary Kiln Incinerators - Rotary kiln incinerators, like the other types, are designed with a primary chamber, where waste is heated and volatilized, and a secondary chamber, where combustion of the volatile fraction is completed.

Introduction. Bucket elevator is used to vertically lift mashed limestone, coal, gypsum, clinker, dry clay and other block granular materials and raw materials, cement, pulverized coal, and other powder materials.According to the running speed of buckets, bucket elevators can be combined with centrifugal discharge type, gravity discharge type and mixed discharge type.

Depending on the area of application such as boilers, furnaces, kilns, ovens etc, temperatures and atmospheres encountered different types of refractories are used. Typical installations of refractories are shown in Figure 2. Figure 2a. Refractory lining of a furnace arch (BEE, 2005) Figure 2b. Refractory walls of a furnace

Rotary kiln incinerators usually have a length-to-diameter (L/D) ratio between 2 and 8. Rotational speeds range between 0.5 and 2.5 cm/s, depending on the kiln periphery. High L/D ratios and slower rotational speeds are used for wastes requiring longer residence times. The kilns range from 2 to 5 meters in diameter and 8 to 40 meters in length.
