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


Slide4 l.jpg

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

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


Slide10 l.jpg

Harvesting studies

  • Harvesting methods

  • Combination of machineries

  • Capacity measurements

  • Defining period length of harvest

  • Defining yield and losses

  • Defining d.m.values


Slide16 l.jpg

Storage studies

  • Different cover methods

  • Different stacking methods

  • Time consumption

  • Cost calculating


Slide20 l.jpg

Upgrading to pellets or briquettes

  • Capacity and quality measurements

  • Electrical consumption measurements

  • Optimizing processing parameters:

    - Grinding, sieving, steam conditioning

    - Die type

    System analysis






Slide25 l.jpg

Combustion

  • Combustion tests

  • Emission measurements

  • Ash melting characteristics

  • Combustion efficiency
