ASH ADHERENCE ESTIMATING METHOD TO SEWAGE SLUDGE INCINERATION TREATMENT DEVICE, AND SEWAGE SLUDGE INCINERATION METHOD USING THE METHOD

摘要

PROBLEM TO BE SOLVED: To provide an ash adherence estimating method for more correctly estimating the generating conditions of ash adhesion to an incinerator or the like when sewage sludge is subjected to incineration treatment, and to provide a sewage sludge incineration method for suppressing the generation of ash adhesion based on the estimated result.;SOLUTION: The respective contents of the components of Fe₂O₃, CaO, Na₂O, K₂O, MgO, SiO₂, Al₂O₃, TiO₂ and P₂O₅ in incineration ash obtained by incinerating the sewage sludge to be treated are beforehand specified, and, based on the specified compositions of the respective incineration ash components, the specified index to be calculated is obtained.;COPYRIGHT: (C)2010,JPO&INPIT
