ABSTRACT:
A method for treatment of sludge is disclosed, wherein the sludge has a liquid part and metal-containing particles intermixed therein. The particles comprise metal, metal oxide or metal hydroxide and the method comprises the following steps: atomising the sludge; supplying the atomised sludge to a flame of a burner provided in a furnace; bringing the liquid part of the sludge to vaporize by means of the flame while maintaining said flame by means of a separate fuel supply; and bringing at least part of the metal-containing particles to melt by means of the flame. This provides an efficient method for taking care of waste material from plants in the steel or petrochemical industry, for example.
