摘要: Abstract Of two types of willow chip (28 and 50 mm cutting length), chunk (100 200 mm length) one type forest (28 mm the pressure resistance to air flow during ventilation was measured. The influence velocity particle size has been determined results are described by a mathematical equation. measured correlated very well with distribution different types. lowest found in long at only 2 Pa/m an rate 0.1 m/s, while highest 28 mm material 39 Pa/m. shown be factor 10 100 lower for these wood fuels than agricultural crops like rape seed grain.
