O-21 Evaluation of mixed pellets of waste plastics and waste wood combustion behavior in CaCO_3 calcination process

Abstract

To clarify the combustion behavior of mixed pellets of waste plastics and waste wood injected into CaCO_3 calcination furnace, a combustion test of mixed pellets has been carried out in the electric furnace and commercial furnace. A burning time of mixed pellets was about 18sec at 1000 degree C. Moreover, it is considered that a property such as the mixed ratio of waste wood can affect combustion behavior. From the result of mixed pellets injection into CaCO_3 calcination commercial process, it was clarified that mixed pellets are available in equivalent to the coke oven gas.
