Dryers Rotary Dryers Ethanol Biomass Torrefaction

Mar 11 2020 biomass feedstock drying is a key operation for producing durable and storage stable pellets the operation reduces the average moisture content from about 50 per cent wet mass basis to five seven per cent the rotary drum dryer is the most common type of dryer used for this task 1 2

Definition of torrefaction a thermochemical treatment of biomass at 1000f and 1100f in a lowoxygen environment for a predetermined time interval whereby most volatiles in the biomass are volatilized resulting in a product with very high fixed carbon content

Wood biomass torrefaction plant servoday group torrefaction is the method where wood biomass is heated in a low oxygen environment to a point where chemical changes start occurring at the right temperature and residence time the end product resembles coal in color and physical characteristics it is able to burn alongside coal or cofire in a coal fired boiler and coal power plant
