Zusammenfassung:	PURPOSE:To provide a combustion auxiliary material for furnace with self- burning and to obtain it efficiently, by dehydrating and solidifying a mixture of sludge of sewage and powdered coal in a specific ratio. CONSTITUTION:Powdered coal is added to the blending tank 1 into which sludge of sewage is introduced in a weight ratio of the powdered coal to the solid dried sludge of sewage of (0.5-3):1, both are agitated and blended fully, sent to the flocculating and blending tank 2, a flocculant such as a low cationic high polymer flocculant, etc. is added to it, so that flocks in the sludge are flocculated. The resultant material is then sent to the filter dehydrator 13, dehydrated into
