PROBLEM TO BE SOLVED: To obtain a blowing method for a waste plastic into a waste melting furnace in which coke is replaced with blowing of the waste plastic to reduce the amount of use of coke and further to reduce the amount of wasteful use of coke and the more waste plastic is processed, 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 melting processing thereof, an ordinary temperature oxygen rich air or high temperature air is blown into a coke head 9 from an air fan blade port 7 and a waste plastic is blown into the coke head 9. In the method, an upper end of the coke head is set to a level where the oxygen blown through the air fan blade port 7 disappears also including combustion of the waste plastic, and the waste plastic is blown into between the air fan blade port level and the upper end level of the coke head. |
