Air pollutants generated in municipal waste incinerator, such as chlorinated organic compounds, are closely related to combustion behavior of waste in the furnace. The behavior is very complicated because the wastc consists of various kinds of components and the reaction develops to the direction from surface to inside of the solid with tune. In this paper, as a fundamental study on pyrolysis and combustion of solid waste, experiment for combustion and pyrolysis of sample was conducted and then the weight loss and flow rate of produced gas were measured on line. As a result, weight loss curve showed a combustion term clearly consists of pyrolysis and char combustion terms. A peak of CO gas production was found in each term. In particular, CO gas flow rate increased gradually in char combustion term, and the rate of increase depended on physical factors, such as density, moisture, and shape of the sample. As the temperature of carrier gas surrounding the sample became higher, total amount of CO gas decreased. Moreover, the rate of increase in CO gas production for a sample with 40% moisture was smaller than that for samples with 20% and 10% moisture.
