Due to their high emission of particulate matter, wood fired furnaces have become a focal point of public discussion in Germany. Log-fired single room heaters can be identified as a main contributor to this matter. The particulate matter emitted by outdated as well as modern furnaces directly affects the pollution inside residential areas. This is demonstrated by a test campaign of a fibrous filter system developed by the Technology of Fuels Unit at RWTH Aachen University. The filter system captures the emitted particles and retains them inside a highly porous media. Particles from different households and combustion systems were collected over half a heating season. Afterwards, the chemical composition of the accumulated particulate matter was analysed. Based on the particle composition, the furnace operation can be evaluated and consequently improved. This method can be seen as an integral evaluation of the emitted particles of small scale furnaces under real-life operating conditions.
由于其颗粒物排放量高，烧木炉已成为德国公众讨论的焦点。燃木单室取暖器被认为是造成这一问题的主要因素。过时的以及现代的炉子排放的颗粒物直接影响居民区的污染情况。亚琛工业大学燃料技术单元研发的纤维过滤系统的一项测试活动证明了这一点。该过滤系统捕获排放的颗粒并将它们保留在高度多孔的介质中。在半个供暖季期间收集了来自不同家庭和燃烧系统的颗粒。之后，对累积颗粒物的化学成分进行了分析。基于颗粒成分，可以评估并进而改进炉子的运行情况。这种方法可被视为在实际运行条件下对小型炉子排放颗粒的综合评估。
