Sammanfattning
The purpose of this essay is to review straw conservation systems, from the swath until the straw has been unloaded at the heating plant. Various straw harvesting systems are studied. The harvesting methods are described, as well as the capacities and the resulting material properties. In addition, a number of storage methods are investigated. Procedures of making, conveying and storing briquettes, pellets and powder are investigated. The direct and indirect energy requirements for different harvesting chains are evaluated. The estimates show, with regard to the energy requirements, that straw utilization is very profitable. Cost calculations have been estimated. The figures suggest that a cost of about 0.35 SEK should be attainable for getting the straw delivered to the heating unit.
