Carbon-containing residues are produced from rice husks when used in gasifiers and boilers. To understand the problem of incomplete carbon conversion, a study of combustion, pyrolysis, and gasification of rice husks is needed. Thermogravimetric experiments were carried out using rice-plastic husk pyrolysis equipment in the air atmosphere with a single airflow of 25 m s −1 under different temperature conditions and mass of rice husk (8, 9 and 10 kg). The results showed that at temperatures higher than 700°C there was an incomplete conversion, whereas at low temperatures a complete conversion occurred. The mass of the white and grey colour of rice husk ash increased with increase the rice husk mass while the black colour decreased. According to statistical analysis shows that the yield of ash with white colour has significant effect (P<0.05) while the grey and black colour was no significant effect. On the other hand, the amount of rice husk on the ash recovery of rice husk was no significant effect. Kinetics of combustion, pyrolysis, and gasification are also very sensitive to the rate of heating.
