A STUDY ON THE COMBUSTION OF SOLID FUEL OBTAINED BY HYDROTHERMAL TREATMENT OF THE MUNICIPAL SOLID WASTE

Abstract

In this study, combustion behavior of hydrothermal treated municipal solid waste was experimentally investigated by its thermogravimetric analysis in nitrogen and air environments. The kinetic parameters of the combustion process were calculated using the reaction order model and the diffusion model (D₃) to predict the combustion reaction mechanism of hydrothermal treated municipal solid waste and compare with Indonesian brown coal. Simultaneously, also from the thermogravimetric analysis data, the combustion characteristics index of hydrothermal treated municipal solid waste and Indonesian brown coal were calculated. The experimental results could help to orient the use hydrothermal treated municipal solid waste for industrial combustion processes.
