Experimentally determined MSW sample incineration heat and revealing its auto-combustion capability
Journal Title: Metallurgical and Mining Industry - Year 2017, Vol 9, Issue 7
Abstract
The current research experimentally simulates the combustion processes for municipal solid wastes of a given composition with a boiler-utilizer pursing the objective to study the opportunities for autocombusion and to determine the heat of incineration. The research is carried with the samples made from municipal solid wastes (hereinafter referred as MSW) simulating their average morphology in the city of Kyiv, Ukraine. Their incineration was performed in the laboratory boiler-utilizer and the incineration heat of 1 kg of solid waste has been defined. The values of incineration heat, as established by the experiments, correspond to the predicted values. However, it was not possible to keep the required temperature of 850 ℃ in the experimental equipment and to reach auto-combustion even with that MSW composition, with which auto-combustion is possible in accordance to the Tanner diagram. In the article, we substantiate that the MSW combustion process for the industrial furnaces cannot be studied with an experimental boiler-utilizer; for this purpose it is expedient to use the appropriate calculation models based on the thermal balance sheet of the furnace. For the practical use, the research has showed that the industrial plants and sites, which practice MSW incineration, can quite accurately determine the heat of MSW incineration by direct combustion of the appropriate samples.
