Pressure Resistance During Ventilation of Different Types of Wood Chips as a Function of Particle Size and Particle Form

D. Kuptz, P. Turowski & H. Hartmann
Pressure resistance during ventilation was measured for a high variety of wood chips (n = 95). Samples were produced using different raw materials and chipper settings. Physical fuel properties were analyzed according to European standards (bulk density, particle size distribution) but also by using a continuously measuring image analysis device (particle length, particle form). Pressure resistance (Pa m-1) was measured within a custom build flow cylinder (2 m height, 0.4 m³ filling volume) and was...
