Torrec's technology combines three owner parties more than 60 years of technological experience in the wood drying and thermal treatment, thermally treated wood pelletizing and processing of wood chips and sawdust.
Key features of Torrec's technology
- Vertical reactor, where material handling is carried out by means of gravity (no drives / actuators in a hot state, own IPR)
- Energy-saving rapid drying at high temperature
- Safe and low-cost inertisation with steam and accurate process control (own IPR)
- Own special solutions in pellet press, which enables low O&M cost and high availability
Torrec's plant concept is a compact and simple, which will reduce the investment costs and improve productivity. The process is suitable also for lower quality wood chips (does not require debarking). Energy needed in drying is produced using fines that are removed in screening phase. At the same phase, also sand and other foreign matter is removed that causes pellet press the extra wear, and thereby reduce the utilization rate. The combination of biocoal production and the CHP plant allows the raw material exploitation in the best way.
The company has an industrial demonstration plant in operation in Mikkeli, Finland. Company's technology can be scaled to large-scale industrial production capacity (50 ... 125 000 t / a).
