Description:

The report summarizes the results of several studies relating to hazardous waste combustion in cement and lime kilns. The tests included in the study are four kilns tested by the U.S. Environmental Protection Agency, four kilns tested by State agencies or the kiln operator, two Canadian tests, and one Swedish test. The predominant types of wastes tested included chlorinated organic compounds, aromatic compounds, and metal-contaminated waste oil. The kiln types include lime kilns and cement kilns, which included the dry, wet, and preheated processes. Fabric filters and electrostatic precipitators (ESPs) were the pollution control devices used in these processes, and the primary fuels included coal, coke, coal/coke, fuel oil, and natural gas/coke. The parameters examined in the report were Destruction and Removal Efficiency (DRE) of the Principal Organic Hazardous Constitutents, particulate and HCl emissions, metals, and the effect of burning hazardous waste on SO2, NOx, and CO emissions. The primary conclusion of the study is that DRE's of 99.99% or greater can be obtained in properly-operated calcining kilns. Particulate matter can increase when chlorinated wastes are burned in a kiln equipped with an electrostatic precipitator. Those kilns equipped with fabric filters showed no change in emissions.
