The engineering principle and performance characteristics of rotary kiln incinerator system were analyzed from the types and scale of hazardous waste incineration,process selection,the design of rotary kiln incinerator,and the analysis of engineering example with an example of hazardous waste incineration disposal engineering in one country. The results show that the process of rotary kiln,second combustion chamber,waste heat boiler,quench tower,semi-dry reaction tower, dry acid tower, and bag-type dust collector was adopted. It controls the rotary kiln temperature about 850 ℃,the residence time of haz-ardous waste in rotary kiln around 60 minutes,the speed of rotary kiln is 0.2~1.0 r/min,the angle of rotary kiln is 2°. The tem-perature of second combustion chamber is greater than 1 100 ℃,the residence time of smoke in the combustion chamber is greater than 2 seconds. Under this condition, clinker ignition loss is less than 5%,burned removal rate is greater than 99.99%, and the flue gas emission meets GB 18484—2001.
