Rotary kiln incineration systems are ideal for processing mixed industrial and hazardous wastes that include a combination of solid, sludge, and liquid waste streams.
The incinerator consists of a slagging rotary kiln followed by a vertical afterburner. Combustion gases, after exiting the afterburner, pass through a spray dryer, a baghouse, a saturator, a two stage packed bed scrubber, and exit out the stack. Because the Clean Harbors incineration system is
Incineration by slagging rotary kiln is a process in which wastes are incinerated in a rotary kiln at temperatures greater than those used in standard rotary kilns.
- Available in slagging or nonslagging models PROCESS Rotary kiln is a pyroprocessing device used to raise materials to a high temperature (calcination) in a continuous process. The basic components of a rotary kiln are the shell, the refractory lining, support tyres …
Most rotary kiln incinerators in Europe operate in ashing mode, as the overall operating costs turned out to be lower than in slagging mode. All rotary kilns presented in this work run in ashing mode as well. Fig. 1 shows a typical temperature profile inside the kiln, at the hot face of the refractory lining.

A high-temperature, slagging rotary kiln hazardous waste incineration system with modern combustion, heat recovery and air pollution control equipment was put in operation at PPG Coating and Resin Plant in Circleville, Ohio in the latter part of 1987.
Description. The lime kiln called drum rotary kiln, advanced structure, scale ends of combined rotary kiln lime kiln reliable sealing.The air leakage coefficient is less than 10% using composite refractory materials, to reduce radiation loss.
Rotary Kiln Afterburner 3 Figure 1: Typical Rotary Kiln Incinerator (adapted from EPA-530-R-94-014) Rotary Kiln Incinerators Rotary kilns were used at 12 case study sites. The rotary kilns were used to treat most forms of waste, including solids, liquids, sludges, and debris. Figure 1 is a schematic diagram of a typical system.
Slagging Rotary Kiln Process The slagging, high-temperature process was born in Eu-rope about two decades ago, largely out of a necessity to destroy steel containers (usually steel drums) by melting them inside the rotary kiln in a pool of molten material (slag). The slag is …
