PROBLEM TO BE SOLVED: To economically recover energy in a sludge treating facility. SOLUTION: The above problem is solved by generating and blasting compressed air by a supercharger 5 by using exhaust gas X4 from a fluidized bed type incinerator 2, supplying one part X3 of the compressed air generated in the supercharger 5 to a preheater 3 for preheating air for combustion, and supplying the remaining compressed air X5 to a PSA type oxygen separator 9 and obtaining oxygen of high concentration.
