A theoretical combustion kinetics model for domestic green waste.

A thorough understanding of the combustion kinetics of domestic green waste is of great significance for its incineration efficiency and energy harvesting characteristics. The published literature regarding the combustion kinetics of domestic green waste primarily employs experimental techniques. There is a need to develop theoretical basis for combustion kinetics of domestic green waste, leading towards the development of comprehensive dynamic models. In this study, a theoretical combustion kinetics model has been developed for domestic green waste, which is primarily composed of kitchen and garden waste. The developed model is based on Badzioch's relationship. A correlation between the rate of fuel weight loss and the heating rate has been introduced in the model. Moreover, time parameter has been replaced with temperature which aids in obtaining Thermogravimetric and Differential Thermal curves directly. The theoretical combustion kinetics model has been rigorously tested empirically in order to ascertain its validity and appropriateness. The results show that the theoretical Thermogravimetric and Differential Thermal curves are reasonably accurate, with < 10 % difference compared to experimental data. The developed combustion kinetics model for domestic green waste thus provides invaluable insights into the combustion phenomena and paves the way for the engineering design of corresponding incineration equipment.
