<p>PROBLEM TO BE SOLVED: To provide a treating method of complex waste material, with which in the case of high temp. melting, the high calorific power and the performance as reduction material in plastics are effectively utilized and also, the concrete treating condition is set and the melting treatment can safely and efficiently be applied without dismantling and classifying the complex waste materials. SOLUTION: When the melting treatment of the complex waste material is executed by charging the complex waste material containing at least metal and plastics together with coke into a multi-function melting furnace 1 having multi-stages of blasting tuyeres 9a, 9b and drying, heat-decomposing, burning and melting, the upper end level of the coke bed is set between the upper stage tuyere 9b and the lower stage tuyere 9a, and hot-blasting enriching oxygen is executed into the coke bed 13 from the lower stage tuyere 9a.</p> |
