To decrease the volume of sewage sludge and convert it to the resources, a unique compact sludge-melting furnace was developed. The wet sludge was fed directly in the furnace by snake pump and oxygen enriched air by PSA unit was used for melting the sludge at a temperature of approx. 1300 to 1500oC. The melt slag discharged from the bottom of the furnace was crystallized on a crystallizing conveyer. Produced slag was effectively usable as high-quality aggregate including base course materials and asphalt mixtures On the other hand, incinerated exhaust gas was discharged from the top of the furnace, and was cooled down after secondary combustor. Due to achieving a mild combustion, the amount of generating of particulates and NO_x in the exhaust gas decreased extremely. In this paper, combustion mechanism of dehydration sludge in the furnace was discussed.
