Abstract: A flame guniting lance comprises a water-cooled casing made up of pipes (1 and 2). Arranged concentrically inside the casing are pipes (4) for supplying a mixture of powdered refractory material and fuel, and pipes (3) for supplying oxygen. Each pipe (3 and 4) is respectively fitted with a nozzle (5) for supplying the mixture of refractory material and fuel, and a nozzle (6) for supplying oxygen, the nozzles being arranged in pairs and coaxially in each pair. The outlet cross-section of each nozzle (5) is positioned below the outlet cross-section of each nozzle (6) within a distance of 1 to 5 times the inside diameter of the nozzle (5). The walls of at least one of each pair of the nozzles (5 or 6) are partly or completely other than cylindrical in shape.
