Abstract

A slag slurry drum filter is mounted for rotation about an axis of rotation (3) and comprises a mesh filter (4) comprising an inner and an outer surface. A slag slurry drum filter cleaner for mounting on the outer surface of the slag slurry drum filter comprises a fluid supply (35); a controller (9); an array (8a, 8b) of spray nozzles (7) to receive fluid from the fluid supply and supply some of the fluid through the outer surface of the filter to the inner surface of the filter; and valves (35, 36) associated with each spray nozzle. Each valve is operable to control fluid from the fluid supply under the control of the controller. For at least one valve (36), the same valve is associated with more than one nozzle (7).
