    Abstract

    This report describes the tests of different techniques for removing the particulates from producer gas from the 100 kW two-stage down-draft gasifier at DTU1 . The goal of the tests was to identify and implement methods to remove soot particles from producer gas with low tar content. During the five days of gasifier operation, cartridge filters, bag filters were tested. Attempts to test an electrostatic precipitator failed. Cold gas cleaning systems using fiber filters (bag filters and filter cartridges at approx. 90°C) were successfully demonstrated with collection efficiencies between 96-99%. A bag filter was successfully operated for 50 hours with automatic cleaning by back-flushes with N2.
