To decrease the volume of sewage sludge and convert it to the resources, a unique compact sludge-melting furnace was developed. A dehydrated 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 approximately 1350℃. 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. On the other hand, the melt slag discharged from the bottom of the furnace was crystallized on a crystallizing conveyer. In this paper, simulation model for combustion of dehydration sludge in the furnace was developed. The experimental results of SO_2 and CO_2 concentrations in the exhaust gas and height of the sludge cone in combustion tests were in close agreement with those of the simulation.
