Thermal Modelling of the Torrefaction Process Using the Finite Element Method

Abstract This paper focuses on the thermal characteristic of torrefied pinecone pellets. The resistivity heating system was used for torrefaction purposes. conducted at 523 K different holding times 5, 10 and 15 minutes. behaviour pellet numerically predicted using pdepe algorithm. A parabolic 2-D heat transfer equation to estimate profile across pinecone. effect interactive atmosphere numerical solution also examined. pelletisation performed a ring-die temperature 70 °C.
