Removal of fine particulate matter from exhaust gases by metallic microsieves
Abstract
Metallic micro sieves are a promising filter media to remove fine particulate matter from gases. Therefore, a study has been carried out in order to show its filtration performance (pressure drop and filtration efficiency) in respect to different boundary conditions (volume flow, temperature). Experiments showed high particle retention rates after a short time, depending on the hole diameter. By applying micro sieves with an average pore diameter of 8 Mym, a retention rate of more than 99 % could be obtained after 90 - 160 seconds. The practical application of micro sieves as filter in the exhaust gas of wood fired furnaces gave good results as well.
