METHOD FOR EVALUATING PUTTING WASTE PLASTIC INTO BLAST FURNACE

摘要

PURPOSE: A method is provided to evaluate the work of a blast furnace on putting the waste plastic into a blast furnace is provided by easily presuming a metathesis rate as an economic evaluation item through a calibration coke ratio. CONSTITUTION: A ratio of waste plastic input inside a blast furnace and a radiation amount of waste plastic are measured. A calibration coke ratio is calculated by an equation, calibration coke ratio = coke ratio on all coke work - (waste plastic radiation amount/coke radiation amount) x waste plastic blowing ratio. Accordingly, the work of the blast furnace for inputting the waste plastic is evaluated.
