Combustion Kinetics of Wet-Torrefied Norwegian Biomass Fuels

Q.V. Bach, B. Pfeiffer, K.-Q. Tran, R. Khalil & Ø. Skreiberg
Wet torrefaction, also referred to as hydrothermal carbonization, is a promising pretreatment process to convert a wide range of biomass to energy dense solid fuel. In this process biomass is treated in hot compressed water within the temperature window of 200–260°C. The pressure can be controlled to be higher than the saturated vapour pressure in order to avoid the energy requirements for phase transformation of water in the form of latent heat. The solid remaining...
