Belt Dryer Design Basis:The Metso Kuvo belt dryer is a low-temperature dryer which is designed toremove water efficiently by evaporatingmoisture from wet biomass, like bark, woodchips, sawdust, bagasse etc. The dryer is ableto utilize various low-temperature heatsources; waste heat, low-pressure steam, hotwater, or hot air – no primary energy isneeded. Dry biomass can then be used asbiomass fuel, or in fuel making process . Thedrying process is gentle to the product and ithas high availability and high capacity

Belt Dryer For Biomass• Modular Structure Provides flexible dimensioning
• Capacity- Evaporation 2 - 20 tons of H2O/h- Material flow 20 - 200 loose-m3/h
- Dry content in typically 30-60 %
- Dry content out - up to ~90 %
• Size / unit- Area 40 - 260m2
- Length up to 50m (165 ft)- Width up to 6m (20 ft) For bigger capacities, several
dryers can be installed one on topof the other to save floor space

Belt Dryer For Biomass• Utilization of waste heat
Two heat sources likehot water and steam or
two hot water sources can becombined in the same air heat
exchanger
Belt Dryer can utilize severaltypes of low temperaturesources
1)Low temperature water40°C…120°C (104°F -250°F)
2) Low pressure steam
3) Hot waste gas
4) Hot oils
