摘要Incineration is one of the major methods for processing municipal solid waste (MSW) harmlessly; however, it could lead to low combustion efficiency and secondary pollution problems because of the high moisture content and low energy density of MSW. Torrefaction has been reported to be effective in removing moisture and improving combustion properties in various materials, such as feedstock and wood. The aim of this study was to investigate whether torrefaction could be used as a practical pretreatment method by improving the combustion properties and reducing the chloride content of MSW. Typical combustible components in MSW were chosen and torrefied at various temperatures (250, 300, 350, 400, and 450 degrees C), under a N-2 atmosphere for 30 min. The calorific values of MSW became higher after torrefaction between 250 and 350 degrees C. At a torrefaction temperature of 300 degrees C, the torrefied MSW sample produced similar calorific values to those of standard coal. Under this condition, the chlorine content of the torrefied MSW sample was 57% lower than non-torrefied samples. In addition, the grindability of the torrefied sample was better than that of synthetic MSW. The improved grindability, lower chlorine content, higher heat value, and superior combustion characteristics of torrefied MSW suggested that torrefaction may be used as an effective MSW pretreatment, and the torrefied MSW is more suitable to be used as fuel than non-torrefied MSW.
