A method and an arrangement for treating wet material which is difficult to treat, such as sewage sludge, by combustion, wherein the material being treated is dried in a steam dryer (3) and the dried matter is combusted in a combustion apparatus (1). For the heat requirement of the steam dryer (3), steam is superheated by the aid of the thermal energy generated by the material combusted in the combustion apparatus (1), and the superheated steam is taken to the steam dryer (3) for drying the material being treated. The amount of heat released from the fuel in the combustion apparatus (1) is transferred into the steam circuit of the steam dryer (3) in its entirety. |
