Abstract
In recent years, troubles of fire and burst at waste disposal processes have been rising. In this report, we investigated the cause of the large scale burst of Mie RDF power plant occurred in August last year. We especially focus attention to the final cooling process of RDF production line. We simulated the cooling and heat production characteristics of stored RDF. Then we obtained two conclusions. First, when RDF is piled up as a cube with side length of 3 meters in a pit silo, minimum ignition temperature is about 54 degrees. Second, it is important to keep the temperature under 40 degrees and to limit the height of piled up RDF under 5 meters at storage.
