Title [sv]
Ny energieffektiv flishuggningsteknik för skogsindustrin
Title [en]
New energy-efficient wood chipping technology for the forest industry
Abstract [sv]
Flisning av ved i industriell skala görs idag med skivhuggar, men en innovation av svenska småföretagare bygger på en modifierad trumhugg med flera fördelar jämfört med konventionella flishuggar. Den nya flishuggen kräver lägre installerad effekt, förväntas ha högre verkningsgrad och ger jämnare kvalitét på flisen. Jämn fliskvalitét minimerar andelen rejekt, ökar utbytet av vedråvara och ger energibesparingar i efterföljande processled. I projektet kommer den nya huggtekniken att utvärderas och jämföras med konventionell teknik.
Abstract [en]
The main part of the feedstock used for pulp and paper, wood biorefining, and bioenergy is converted to wood chips using energy-intensive conventional chipping technology based on disc chippers. An innovative new type of drum chipper offers several advantages compared to conventional technology. The new wood chipper is flexible as it allows settings to be adjusted during running, which permits optimized chipping without process interruption. It demands less installed power, is expected to have higher energy efficiency, and provides more even wood chips quality. Even wood chips quality minimises the reject fraction, increases the yield, and gives energy savings in subsequent process steps. The project will evaluate the new wood chipping technology and compare it with conventional technology. Pilot-scale wood chippers and new advanced evaluation methods will contribute to making the area researchable and provide a scientific foundation for new energy-efficient wood chipping technology.
