  1. Reed canary grass as an energy crop Håkan Örberg Unit of biomass technology and chemistry

  2. Reed Canary Grass research at SLU/BTK   Establishing crop Crop treatment   Harvesting and transport   Storage   Upgrading to Briquettes and pellets   Combustion

  3. Perennial rhizomatous GrassReed Canary Grass • A high yield crop in humid areas • Resistant to diseases and damage by insects • Establishing by seeding • Agricultural machineries can be used by harvesting and seeding

  4. Delayed harvest of Reed Canary Grass • 1. Washing by winter rain gives lower K and Cl contents • 2. Harvest in early spring time gives dry material . 12-15 % water • 3.High losses

  5. Regions in screening trails

  6. Yield of delayed harvested RCG in Northern Europe

  7. Fertilizing kg/ha • Year 1+2 N P K • 150 40 150 • Year 3-10/year 80 10 10 • Based on a yield of: 7500 kg/ha

  8. Harvesting studies • Harvesting methods • Combination of machineries • Capacity measurements • Defining period length of harvest • Defining yield and losses • Defining d.m.values

  9. Storage studies • Different cover methods • Different stacking methods • Time consumption • Cost calculating

  10. Upgrading to pellets or briquettes • Capacity and quality measurements • Electrical consumption measurements • Optimizing processing parameters: - Grinding, sieving, steam conditioning - Die type System analysis

  11. Bio fuel pilot plant

  12. Conveyor and shredder

  13. Briquette machine

  14. Pellets press

  15. Combustion • Combustion tests • Emission measurements • Ash melting characteristics • Combustion efficiency

  16. Boiler 150-600 kW

  17. Thank You for listening
