홈페이지논문 초록 (Abstract)
"In this study, a torrefaction experiment was carried out using domestic woody biomass (waste wood and logging residue) and ove rseas herbaceous biomass (PKS: palm kernel shell and bagasse). Torref action was performed in a nitrogen atmosphere using a batch-type appar atus, either with changing torrefaction temperature or with changing duration at a constant temperature. Here, only the oxygen contained in the biomass was used in the torrefaction experiment. The physical and chemical properties of biomass fuels produced under various torrefaction conditions were investigated to determine thei r characteristics as fuels for coal firing power plant. Based on thermogravimetric analysis (TGA), proximate analysis of fou r kinds of biomass, and the result of varying the torrefaction tempera ture and duration, each of the biomass residues was torrefied for 30 min at a temperature range of 250-350 A degrees C in an anaerobic co nditions. Consequently, when compared with the raw material, each of the torrefied materials showed lower moisture and volatile mat ter content, fixed carbon and ash content, and higher calorific value."
