A test apparatus enabling to determine the length of a fuel bridge over an opening was developed in order to describe the physical-mechanical fuel characteristic of bridging. Two such testers were applied by 6 European partners who applied a uniform test procedure on a total of 85 large biomass fuel samples of 2 m3 volume. All samples were further analysed for angle of repose, moisture content, bulk density and image analysis parameters (e.g. particle size...
