PROBLEM TO BE SOLVED: To provide an economical method, in which waste material can reach its required melting point without difficulties, despite an external fuel being unnecessary. SOLUTION: Some loose waste materials, more specifically dusts, are fed into a furnace chamber 2. A layer of waste materials formed at a bottom region of the furnace chamber 2 may receive direct action of at least in a level of sound speed of industrial-based oxygen of which amount is less than that of theoretical value, under an assistance of a plurality of lances 10 placed at dispersed locations. In combustible substances are melted with heat generated by a continuous combustion of the waste materials. Residual ignitable gas which is not yet ignited is supplied to a secondary combustion chamber via a gas outlet cylinder 3. |
