Energy optimization of thermal treatment of municipal solid waste

Since the content of municipal solid waste (MSW) varies from region to region, from country to country, from province to province, data on pyrolysis of the municipal solid waste prepared in different menus are not available in the literature. In this study, detailed literature search on energy production technologies from municipal solid wastes was carried out. Experiments have been carried out to investigate the effect of temperature on final product yield and methane gas yield in particular. In addition, rotary kiln pyrolysis reactor is numerically modeled, and mass, energy, momentum and heat transfer equations are derived. At the same time, a finite element model was constructed for a pyrolysis reactor designed at three different diameter / aspect ratios. A total of 81 computational fluids dynamics analyzes were carried out by using different values for inlet temperature, particle size and rotation speed with data from Kocaeli province environmental situation report' 2015. According to the analysis conditions, where the maximum methane gas yield is obtained, the energy potential that can be obtained from the municipal solid wastes of Kocaeli province was calculated. It has been observed that the experimental data overlaps with the finite elements analysis in terms of methane yield. Accordingly, it has been calculated that the annual electric energy that can be produced from the methane gas is about 156 GWh when the municipal solid wastes pyrolyzed.
