Complete processes - all from a single source
ANDRITZ supplies the complete process equipment for biomass drying, from wet milling to drying, fine milling and pelleting - all from a single source! The product portfolio for biomass also includes complete wood yards, chippers to produce wood chips, grinders, pellet presses, and biomass-fired power stations.
In addition to pellet mills and in combination with drying, ANDRITZ can also supply complete energy generating systems, from the raw material to electric power and/or steam generation. In most cases, biomass (bark, wood chips, sawdust) has to be dried before being used in pelleting, briquetting, incineration, and gasification.
By reducing the water content, the calorific value increases from 2 kWh/kg to approximately 4.5 kWh/kg. This cuts the transport and storage costs and creates the ideal conditions for direct firing or optimum pelletizing properties, both for industrial and for high-grade wood pellets. As a result of the drying process, less fuel is required to generate energy, which also reduces the emissions caused by the firing process.
