This study focused on new utilization of pin-holed fibrous filter with longer life and more moderate performance than conventional filters. 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.

本研究主要针对针孔式纤维过滤器的新用途，其比传统过滤器具有更长的使用寿命和更温和的性能。本研究的动机是增加生物质燃烧能源作为一种碳中和和可再生能源。生物质燃烧不仅会产生二氧化碳，而且会产生大量的纳米颗粒物，对人类健康和全球气候产生影响，本文研究了家用小型烤炉、木材炉和颗粒炉的颗粒物和气态污染物排放特性，并与管式炉的实验室规模实验进行了比较。小型炉灶排放的颗粒物中有70~ 90%属于PM 1颗粒物，初始阶段的颗粒物排放率比后期持续燃烧阶段的颗粒物排放率大50%以上。从批量测试的颗粒在管式炉中燃烧，颗粒排放量每燃料质量被发现增加燃料负荷。此外，对针孔过滤器进行了各种条件下的初步试验。结果表明，影响针孔过滤器性能的关键因素是针孔周围气流的附加收集效应，在试验条件下，针孔周围气流的附加收集效应约为2%。
