F111 下水汚泥のバイオソリッド燃料化(OS3 バイオマス・新燃料・環境技術)

抄録

We have introduced the sewage sludge drying and pelletizing process that transforms sewage into low water content (less than 10%) and spherical pellet. This report presents the description of the sewage sludge drying and pelletizing process, quality of dried sludge pellets and the basic results of the co-firing test of dried sludge pellets with coal in pulverized coal-fired furnace, the results of co-firing test of dried pellets in municipal solid waste incinerator. It is concluded that dried sludge pellets had low water content of 5% and about 50% of heat value of coal. Also, co-firing of dried pellet results in good operation in pulverized coal-fired furnace and municipal solid waste incinerator.
