The emission of odor, characterized by the combustion conditions and biomass types resulting from the use of a biomass incinerator, was analyzed. The following biomass types were considered: bark, board waste, sawdust, wood flour, wood fiver, wastewater sludge, and timber wastewater. As a study method, the physico-chemical characteristics of each biomass type were analyzed to predict the potential substances that might be emited under incomplete combustion conditions. And, the emission components of odor emission by biomass were analyzed at the laboratory level using a combustion device. In addition, the characteristics of the contaminant (odor) emission per mixture ratio of biomass were analyzed in a stoker incinerator that is in operation in an actual establishment at a scale of 300 ton/day. In the biomass emission experiment using the combustion device at the laboratory level, the major substances such as Acetic acid, Styrene, Toluene, Benzene, Dichloromethane, etc. were analyzed, and these components were determined to increase odor index. VOCs measurement in the outlet of the stoker incinerator indicated that Acetaldehyde, Ethanol, Acetonitrile, Ethyl acetate, Toluene, etc. were detected as the major substances. These were similar to the emission substances presented by the experiment that had investigated emissions by biomass type. A study on the Effect of Operational Conditions in biomass stocker incinerator on the concentration of odorous materials emitted from stack showed a close relationship between the input by biomass type and urea, temperature in the incinerator, and the tendency to emit/produce odor.
