Occurrence of Transient Puffs in a Rotary Kiln Incinerator Simulator. 2. Contained Liquid Wastes on Sorbent

摘要

The paper gives results of a study of the generation of transient puffs resulting from the batch incineration of liquid waste into a 73 kW rotary kiln incinerator simulator. The liquid was added onto a sorbent, enclosed in cardboard cylinders that are introduced into the combustion chamber one at a time. A statistically designed parametric investigation determined the effects of liquid mass, liquid composition, kiln temperature, and kiln rotation speed on the total magnitude and instantaneous intensity of the pollutant puff leaving the kiln. Liquid wastes investigated included toluene, methylene chloride, carbon tetrachloride, and No. 5 fuel oil. Transient puffs from these wastes were monitored using on-line measurements for FID-measurable hydrocarbons, CO, and integrated particulate filter loadings, although the suitability of any one of these indicators depended on the chemical nature of the waste involved.
