A refractory evaluation project was initiated in 1979 to
study the performance of six selected refractory materials within
the Los Alamos Controlled Air Incinerator (CAI). Determining
refractory resistance to thermal shock, chemical attack, and
plutonium uptake was of particular interest. The experimental
refractories were subjected to a variety of waste materials,
including transuranic (TRU) contaminated wastes, highly
chlorinated compounds and alkaline metal salts of perchlorate,
chlorate, nitrate and oxylate, over the six year period of this
study. Results of this study to date indicate that the use of
high alumina, and possibly specialty plastic refractories, is
advisable for the lining of incinerators used for the thermal
destruction of diverse chemical compounds.
The Los Alamos Controlled Air Incinerator was commissioned
in the mid-1970s to demonstrate the production-scale volume
reduction of transuranic (TRU) combustible solid wastes (l). The
CAI system was selected because the immediate need to solve the
TRU waste problem dictated the use of off-the-shelf components
wherever possible. In addition, the CAI was chosen over other
possible incineration systems due to its flexibility in handling
different waste types, ease of combustion rate control and
completeness of combustion, and its low generation of particulate
emissions. Although originally designed for combustion of solid
wastes, the CAI has since been modified, with the addition of a
high intensity vortex liquid injection burner, to handle a
variety of waste feeds in solid, liquid, and slurry form. At
present the Los Alamos system is the only radioactive waste
incineration facility in the United States permitted for
treatment polychlorinated biphenyls (PCBs).
