Rotary kiln incineration - combustion chamber dynamics

Incineration of xylene/sorbent packs. A study of conditions at the exit of a full-scale industrial incinerator

“…On the basis of review of the video images and on extensive kiln simulator studies (5,13), we have concluded that the bursting behavior better correlates to the macroscale dissolution of the plastic packs rather than the microscale motion associated with homogeneous bed slumping. Upon being loaded into the kiln, the pack drops from the loading platform to the lower edge of the existing bed and the kiln rotation carries the pack upwards and slowly into this existing bed.…”

“…In 1988, the study was extended to periodic batch feeding of containerized wastes. In the first test, plastic packs containing toluene and a clay sorbent were loaded into the kiln (4,5). The data showed that the coupling between bed motion and heat transfer plays a key role during incineration of containerized wastes.…”

Rotary kiln incineration. Comparison and scaling of field-scale and pilot-scale contaminant evolution rates from sorbent beds

“…Over the past four years, we have been studying the incineration of pure hazardous waste surrogates at both field and pilot scales. The results of these investigations have been documented in a number of recent publications (1)(2)(3)(4)(5)(6). The program, which has been conducted in conjunction with personnel from the Louisiana Division of Dow Chemical USA (hereafter referred to as Dow), has focused on obtaining an understanding of those process parameters that impose first-order influence on the ultimate destruction levels attainable in rotary kilns.…”

Steady-State Waste Combustion and Air Flow Optimization in a Field Scale Rotary Kiln

“…A third air inlet design creates a single swirl that is similar to the 'turbulence air' inlet investigated by Leger et al (1992Leger et al ( , 1993, Cundy et al (1989Cundy et al ( , 1991, Lester et al (19XX), and Jakway (1995). Again, the mass flow of air is kept at the same value as in the reference case, which is different from the studies mentioned above where the mass flow of air was increased during turbulence air addition.…”
