ごみのバッチ燃焼時に発生する排ガス成分の測定

抄録

Air pollutants which are emitted from municipal refuse incinerators, like chlorinated organic compounds, are generated corresponding to the state of combustion in the furnace. The combustion behavior of wastes is very complicated because the solid waste consists of various kinds of components and its reaction such as drying and combustion proceeds from the surface to the center of the solid, with time. In this paper, two types of experiments, each of which uses an electric furnace or an actual batch combustor, are conducted to analyze pyrolysis and combustion processes of the solid waste. CO, CO2 and hydrocarbon concentrations are continuously measured in each experiment. Hydrocarbons with low boiling point, which are major gas components generated at waste combustion and pyrolysis, were measured semi-continuously by a micro gas chromatograph, and concentration of total unburned hydrocarbons are measured as total organic carbons by a gas chromatograph. It was shown that the flow rate o the total organic carbon was similar to that of the CO. The similar and different of the gas generation processes in the electric furnace and the batch combustor were discussed.
