Design of an experimental incinerator for alpha waste
Description
An electrically heated controlled-air two-stage incinerator has been designed for burning small volumes (5 kg/h) of solid wastes. Distinguishing features of the design are compactness, relatively lightweight, and ease of assembly made possible by using prefabricated ceramic components to form two combustion chambers surrounded by packed fiber insulation within a steel case. Electric girdle heaters around the two combustion chambers provide 600 to 10000C. These temperatures combined with controlled air give minimum ash entrainment and long combustion gas residence times to yield approx. 109 off-gas decontamination factors with conventional off-gas cleaning equipment. After decommissioning, the design allows for ease of disassembly and convenient disposal of the ceramic components. 24 figures, 1 table
