1 Fundamentals of Energy Analysis of Dryers

thus clear incentives to reduce energy use in drying: to conserve finite resources of fossil fuels to reduce carbon footprint and combat climate change and to improve process economics but it is a challenging task facing real thermodynamic barriers Effective analysis of current energy use is a vital first step in identifying oppor- tunities for savings An initial lower bound of dryer

Compression Wood

Compression wood is found on the underside of leaning stems and branches of conifers Its cells are characterized by unusually high lignin and lower cellulose content The cell walls contain spiral gaps (called ''spiral checks'') along the steeper S 2 microfibril angle that is a characteristic of these tissues (up to ∼45 instead of the normal 5–25 from the tracheid axis) (Fig 12)
