Abstract
To clarify the combustion behavior of waste plastics injected into CaCO3 calcination furnace, a combustion test of granulated waste plastics has been carried out in the electric furnace and commercial furnace. Results of electric furnace test showed that a burning time of granulated waste plastics was about 25 sec at 1000 degree C. Moreover, it is considered that the density of plastics particle can affected combustion behavior. From the result of waste plastics injection test into CaCO3 calcination commercial process, the waste plastics was ignited immediately after the injection in the furnace, and dropped on CaCO3/CaO surface. Thereafter, waste plastics burned while moving with CaCO3/CaO. Furthermore, it was clarified that waste plastics are available as energy source that equivalent to the coke oven gas.
