Abstract
The pyrolysis gasification and ash melting processing plant at Toyohashi Waste Treatment of Recovery and Resource Center has been in commercial operation since April 2002 as the biggest plant of the Mitsui Recycling 21 system (R21). This system is designed based on the concept of scale-up from our model plant which is 24t/d of capacity, and also based on low releases of Dioxins, stable combustion condition and high heat recovery. It is confirmed that the main equipment of this system i. e., pyrolysis drum, high temperature combustion chamber and waste heat recovery boiler achieve stable performance. This paper describes the operation result of these main equipment on the view point of scale-up from the model plant and the first commercial plant of R21 for Yame Seibu Clean Centre (110t/d).
