Motivation of this study is increasing of biomass combustion energy as a carbon neutral and re-generable energy resource. It is known that biomass combustion emits not only carbon dioxide, but also a lot of nanoparticles which affect to human's health and global climate. Characteristics of particulate and gaseous pollutants emitted from small scale ovens or wood and pellet stoves for residential use were investigated as a function of operating conditions, compared with laboratory scale experiments using a tube furnace. 70~ 90% of the particles emitted from the small scale stoves were classified as PM1 particles and the particle emission rate during the initial period was 50% or more larger than that in a constantly combusting period that occurred later in the process. From batch tests of pellet burning in the tube furnace, particle emission per fuel mass was found to increase with fuel loading. Furthermore, preliminary test of pin-holed filter has tested in various conditions. From the results, key factor of performance of pin-holed filter has been found as additional collection effect around flow around pinhole, which has around 2% for tested conditions., 研究課題/領域番号:22710073, 研究期間(年度):2010-2011, 出典:研究課題「小規模バイオマス燃焼炉からの大気環境汚染を防止する「ハイブリッドフィルタ」の開発」課題番号22710073 (KAKEN:科学研究費助成事業データベース(国立情報学研究所)) (https://kaken.nii.ac.jp/report/KAKENHI-PROJECT-22710073/22710073seika/)を加工して作成, 金沢大学理工研究域地球社会基盤学系}, title = {小規模バイオマス燃焼炉からの大気環境汚染を防止する「ハイブリッドフィルタ」の開発}, year = {2012} }
