Metallic microsieves are promising filter media to remove fine particulate matter from gases. Therefore, a study is carried out in order to show its filtration performance (pressure drop and filtration efficiency) in respect to different boundary conditions (volume flow, temperature). This study consists of three different parts: experiments, theory, and consequently, practical implementation. At the conference, a multidimensional model in order to predict the pressure drop of clean microsieves is going to be presented. Furthermore, we will present first results of filtration experiments and integration in the model. Application of microsieves as exhaust gas filters for wood fired furnaces winds up the study.
