The effect of airflow distribution on temperature, liquid smoke, rice husk ash and plastic oil yield using prototype systems of pyrolysis equipment organic-inorganic waste

Abstract

Abstract Airflow influences the pyrolysis process. This study was carried out on air distribution flow in the integrated pyrolysis tool of plastic waste and rice husks with added pipeline inside the rice husk’s reactor furnace and without added it. A total of 10 kg of rice husk, 3 kilograms of plastic burlap, and 25 m s-1 initial air velocity from the blower were used. The results showed that the addition of 1-inch diameter pipelines with 18 holes with a 2.5 mm diameter affected the yield of rice husk oil, husk ash colour (white, grey and black) and the temperature at T4 (16 cm from the base) and T7 (54 cm from the base). In contrast, the other temperature was not a significant effect. Also, the yield of plastic oil produced was not impacted considerably. The yield of ash and rice husk oil (RHO) without using an airflow pipe was higher than using an airflow pipe, but the resulting plastic oil (PO) was lower.
