Technical improvement of systems for harvest, transport, storage and dehydration of wood and straw for energy under consideration of economical aspects
Part I of this study investigates various methods that will both technically and economically optimise the harvest, transport, storage and dehydration of straw and wood used for energy production. With respect to straw, technical improvements to shorten and simplify the in-field drying process are investigated. Furthermore, the properties of different cereal, rape straw and whole plant cereal are examined, and the possibility of briquetting them into a handy fuel is considered. Regarding wood, investigations on the use of a self-propelled maize chopper as a basic machine for comminuting are made. Part II of the study aims at evaluating the economic efficiency of diverse procedures for the utilisation of straw and small diameter log as fuel. The costs of producing heat via biomass comprise the following components: raw material, harvest, transport, storage, dehydration and conversion in heating plants. The evaluations are done using current energy prices. At present market prices, straw and small diameter log are only competitive with coal produced in the Federal Republic of Germany.
