Abstract
The operating experiences of the Yame Seibu Clean Center of a Pyrolysis Gasification and Melting Ash System are reported based on the operation during Dec 1999-Mar 2000. In the system of Yame Seibu Clean Center, the municipal waste pyrolyzed by the pyrolysis durm and the pyrolyzed gas and carbon are burnt in the high temperature combustion chamber. We confirmed the stable combustion at low air ratio around 1.2,while CO emissions were lower than 10ppm. We also confirmed dioxin concentration at the stack less than 0.1ng/Nm3-TEQ. The slag leaching performance was excellent and the release of 6 heavy metals such as Cd, Pb satisfied the soil environment regulations. Bulk reduction of the waste less than 1/112 was achieved by recycling slag and ferrous material, non ferrous material.
