Incineration in Low-Level Radioactive Waste Management at the University of Maryland at Baltimore

摘要

The selection of an incinerator by the University of Maryland at Baltimore was carried out under a demonstration grant from the Department of Energy (DOE). The system selected is a 300 lb per hour dual-chambered, controlled air incinerator. The cost of the unit was $130,000, excluding installation. The interior is lined with high temperature brick rather than a castable refractory. The burners in the upper and lower chambers are ''oversized'' to insure responsive temperature control of 2.5 million Btu/h in the upper chamber and 1.3 million Btu/h in the lower. The prescribed operating temperatures are 1900 to 2100 sup 0 F in the upper chamber and 900 to 1200 sup 0 F in the lower chamber. The system has a rated capacity of 300 lbs/h of type IV, pathological waste, but operational experience has limited our feed rate to 150 lbs/h. (ERA citation 12:049381)
