Three important process temperatures were determined from TGA on the Universal Analysis software. T1 is the temperature
where the thermal degradation process of rice husk begins, at T2 the initial characteristics of rice husk are already changed due to the thermal degradation process, and T3 is the first temperature where the material stops losing mass, remaining only the solid residue. This means that, at temperatures smaller than T3, the burning process of rice husk will be uncompleted.
