摘要： A lance (1) for use during the injection of gases during combustion, comprising a channel (2) within the lance (1) throug which it is intended that gas should flow. The invention is characterised in that the lance (1) is a composite lance comprising a core (3) of a metallic material and a ceramic layer (4) outside of the core (3), in that the outer surface of the core (3) is arranged with a region (7) with a smaller diameter surrounded by regions (6, 9) with larger diameters, and in that the ceramic layer (4) is arranged outside of the core (3) with play (5) between the outer surface of the core (3) and the inner surface of the ceramic layer (4), whereby the play (5) prevents the ceramic layer (4) from forming cracks due to differences in expansion between the core and the layer when temperature changes take place.

摘要： 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 vaporise 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.
