Abstract
There is a drawback associated with incineration of radioactively contaminated wastes in ordinary incinerators because radioactive materials can be released into fly ash and radioactively contaminate downstream components. However, a novel in-furnace air cooling incinerator has a potential to control the release of radioactive materials during combustion of contaminated wastes. In this research, the release of radioactive cesium during incineration of contaminated rice straw residues, as well as the amount of fly ash and the burning speed was investigated.
