The Process Feedstock Characteristics Fuel Preparation Conversion Device Fuel Requirements
Presentation Review • Will review some aspects of fuel handling only • Nothing on: • Feedstocks • Conversion devices
Fuel Handling Operations • Truck weighing • Truck dumping • Screening • Grinding • Drying • Storage • Feeding into conversion device
Weighing Operations • Mechanical Scales • Electronic Scales
Unloading • Manual unloading (e.g., Bobcat) • Self unloading • Dump trucks • Walking floor • Onsite dumper systems • Trailer dumpers • Whole-truck dumpers
Screening • Disk screen • Shaker screen
Grinding • Hammermill hog • Knife hog
Drying • Rotary drum dryers • Suspension dryers • Hot hog • Hot conveyor
Storage Systems • Bins • Live bottom • Hopper • Silos • Metal • Concrete • Bunkers • Sheds • Open pile
Conveying Systems • Belt (e.g., tube, flighted, roller-trough) • Screw or auger • Chain (e.g., flights, drag) • Bucket • Oscillating • Pneumatic • Front-end loaders
Metal Removal • Magnets • Stationary, manual cleaning • Stationary, automatic cleaning • Head pulley • Non-ferrous metal detector
