Abstract
JFE Engineering Corp. developed a high-temperature gasifying and direct melting furnace as a completely new waste treatment system that meets the requirements of a recycling-based society. In 2003, the company completed the delivery of the first plants on order. From a control point of view the plant has long and variable time lag depending on a height of waste in the furnace. This paper presents an outline of the completed plants and describes the control system in which online model prediction is effectively combined with rule-based control. Operational results with the control system show the effectiveness of the system.
