Assessment of Waste Fuel Use in Cement Kilns

摘要

This study was initiated to document current knowledge concerning the use of waste fuels in cement kilns. A number of plants have used wastes of relatively low toxicity to supplement their fuel needs. In addition, researchers in Canada, Sweden, and the United States have successfully demonstrated extremely high destruction efficiencies in cement kilns when burning highly toxic organic wastes. These studies indicate that a significant potential exists for the expanded use of cement kilns to safely dispose of many types of hazardous wastes generated in the United States. The technical as well as economic factors affecting the use of cement kilns to destroy waste materials are reviewed. The recommendations derived from the study propose additional work required to thoroughly understand the impacts of this disposal technique.
