The torrefaction process involves heating biomass to a moderate temperature (~280 °C) in the absence of air. This results in a material containing typically 80% of the heating value of the original biomass, and is transformed into a harder, darker fuel, which is much easier to crush. This process is attractive to all sectors involved in the bioenergy chain: - growers see this is a way of adding value to the biomass they grow and reducing transportation costs (since the fuel is dry and has a greater energy per unit volume); power-generators see this as a simpler fuel to handle in the power stations; and there is also interest in using torrefied biomass as a fuel in other conversion processes, such as biomass gasification to liquid (transport) fuels (BTL).
Furthermore, unlike raw biomass, torrefied biomass does not degrade upon storage and so it becomes attractive for extending the supply window for using biomass. In order for torrefaction of biomass to happen on a large scale much information is needed including: optimisation of the process; combustion behaviour; handling behaviour; safety issues; and economics. The workshop aims to bring together academic and industrial researchers, and other stakeholders interested in biomass utilisation for energy production.
This workshop is subsidised and forms part of the initial dissemination activities of the project: “Premium Upgraded Biomass Solid Fuels- Fundamentals of torrefaction and performance of torrefied fuels”, which is financed by the Energy Programme, Grant EP/H048839/1. The Energy Programme is a Research Councils UK cross council initiative led by EPSRC and contributed to by ESRC, NERC, BBSRC and STFC.
