Experimental Study on the Combustion Characteristics of Municipal Solid Waste
In our country, municipal solid waste (MSW) of low heating value and high water content are always burnt in their original forms. Based on the constituent of Shijiazhuang City’s MSW, nine typical constituent of wastes were blended as actual MSW. In this paper, MSW are chosen to carry out element analysis, industrial analysis and thermogravimetric analysis. Analysis combustion characteristics of MSW and the mixture of MSW and coal adopt WCT-2 High Temperature Computer Differential Thermal Balance. The kinetic parameters of MSW and the mixture of MSW and coal are obtained through the law of Arrhenius and the thermogravimentric curve. The final result indicates that ignition point and activation energy of MSW are obviously lower than those of the coal, and the ignition point of the mixture of MSW and coal are not high. It can be combusted completely below 850℃. And the combustion process of MSW or the mixture of MSW and coal can be separate into two stages, the first stage is water in the MSW evaporated, the second stage is combustion of combustible. There are four stage of weightlessness in the combustion of combustible, it showed that there are influence between each constituent of MSW. All this will offer help for incineration MSW of low-heating-valued.
