PROBLEM TO BE SOLVED: To obtain a blowing method of a waste plastic into a waste melting furnace capable of suppressing production of tar to the utmost for gasification of the same by blowing much waste plastic in a waste melting processing for blowing the waste plastic into the waste melting furnace. SOLUTION: The present method is adapted such that when waste is thrown into a waste melting furnace 1 together with coke and limestone and undergoes drying, thermal decomposition, combustion, and melting for a melting processing of the waste, ordinary temperature oxygen rich air or high temperature air is blown into a coke bed from an air fan blade port 7 of the waste melting furnace 1, and waste plastic is blown into the waste melting furnace 1. In the method 1, waste plastic is blown into an area at 800 deg.C or higher in an upper portion from the upper end of the coke bed. |
