| Abstract |
This study utilizes polyethylene (PE) pellets, derived from waste plastics, as fuel in an industrial boiler. A novel burner system was developed that incorporates pyrolysis in a pre-combustion chamber, followed by combustion in the main chamber. This approach enhances combustion control and efficiency compared to traditional grate-based systems. The burner was applied to an industrial boiler that consumes a significant portion of industrial energy in South Korea. Combustion characteristics, including flame images, smoke scale measurements, and concentrations of carbon monoxide (CO) and nitrogen oxides (NOx), were experimentally assessed. The results suggest that using PE pellet fuel combined with pre-combustion provides a sustainable and efficient solution for converting waste plastic into energy while reducing harmful emissions. |
