Date Jul. 11, 1996An apparatus for and a method of melting fine particles containing carbon, capable of uniformly burning and melting the fine particles throughout the entire zone of the combustion flame. The apparatus includes a triple tube structure including an inner oxygen feeding section having an oxygen inlet tube provided with an oxygen feeding passage, a particle feeding section arranged surrounding the inner oxygen feeding section, comprising a particle inlet tube, a feeding tube and a feeding passage, and an outer oxygen feeding section arranged surrounding the particle feeding section, comprising an outer oxygen inlet tube, a feeding tube and a feeding passage. The front ends of the inner oxygen feeding tube, particle feeding tube and outer oxygen feeding tube constitute a nozzle which serves to inject the fine particles fed through the particle feeding tube together with air and/or oxygen flows respectively fed through the inner and outer oxygen feeding tubes to be burned and melted. |
