| Abstract |
This article presents work done in order to investigate the cause of an explosion during the processing of raw garbage in a volume-reduction processing facility at a Japanese shopping mall. Variable onset temperatures of the exothermal reaction were found as a function of oil content, decreasing from 150°C in the samples containing 10.9-14.1% oil to 114°C when the oil content reached 40%. The disposal process was then simulated in a laboratory-scale facility heated by hot air of 150°C blown into the bottom through nozzles. In the case of the dried garbage containing 14.1% oil, white smoke emitted after several hours, accompanied by an abrupt rise of the temperatures in particular at the bottom of the facility. The maximum temperature reached 1070°C, accompanied by the emission of several gases, including carbon dioxide, carbon monoxide, hydrogen, methane and ethane. Probable mechanisms explaining the observed explosion are discussed. |
