Abstract

The Ecotopia Ikehara of Kurahama Sanitary Facilities Association, in Okinawa Prefecture is a fluidized-bed gasification and ash melting plant. The capacity of this system is 103 ton/day x 3 lines, 309 ton/day in total From June 2011 to February 2012, the third line was operated continuously in 226 days, and demonstrated combustion stability in k)w excess air with very tow emission of carboon monoxide. The most valuable result of low excess air combustion 18 k)w transfer rate of lead to slag in despite ofoxidant atmosphere. Therefore,slag from this plant kept meeting Japanese Industrial Standard fro slag material for road construction (JIS A 5032:2006) in this continuous operation.
