CONVERSION OF ORGANIC SLUDGES TO FUEL
PROBLEM TO BE SOLVED: To convert organic sludges to fuel at low cost, while suppressing heat loss.SOLUTION: The method for converting organic sludges to fuel comprises the steps of, in a state where the organic sludges are piled in an indoor yard: aerating the organic sludges with a high-temperature gas of 50°C to 140°C generated by a cement burning apparatus or a power generator at a rate of 0.2 m/min to 0.4 m/min per 1 mof the organic sludges; and reducing a moisture content of the organic sludges by using fermentation heat by aerobic fermentation thereof. If necessary, a moisture adjusting material may be added to the organic sludges in order to improve gas permeability and handleability thereof. Further, an amount of the high-temperature gas aerated into the organic sludges may be adjusted according to a concentration of COafter the high-temperature gas is passed through the organic sludges or a degree of the organic sludges.SELECTED DRAWING: Figure 1
【課題】熱量損失を抑え、低コストで有機汚泥類を燃料化する。【解決手段】有機汚泥類を屋内ヤードに堆積させた状態で、該有機汚泥類にセメント焼成装置又は発電装置で発生した５０℃以上１４０℃以下の高温ガスを、前記有機汚泥類１ｍ3あたり０．２ｍ3／ｍｉｎ以上０．４ｍ3／ｍｉｎ以下の割合で通気すると共に、好気性発酵による発酵熱を利用して該有機汚泥類の水分を減少させて燃料とする有機汚泥類の燃料化方法。有機汚泥類に必要に応じて水分調整材を添加して有機汚泥類の通気性やハンドリング性を改善してもよく、高温ガスの有機汚泥類への通気量を、高温ガスを有機汚泥類に通過させた後のＣＯ2の濃度又は有機汚泥類の分解度によって調整することができる。【選択図】図１
