CSA SPE 2254:1 9 Guide to wood chip fuel: Characteristics, supply, storage, and procurement. Chemically untreated used wood – residues from debarking, sawing or size reduction, shaping, and pressing processes of used wood that does not contain heavy metals or halogenated organic compounds as a result of its usage and treatment with wood preservatives or coatings and is free of nails, paint, and drywall compounds. Coarse fraction – oversized material, which is outside of the main wood chips fraction after sieving. End users – include project developers, equipment manufacturers, engineering professionals, planning and procurement officers, energy facilities managers, maintenance staff, and those responsible for the operation of wood chips energy systems. Fines fraction – undersize material, which is outside of the main wood chips fraction after sieving. It might contain sawdust and non-combustible material such as soil or sand. Forest, plantation, and other virgin wood – include wood from forests, parks, gardens, plantations, and short rotation forests and coppice; have only been subjected to size reduction, debarking, drying, or wetting. Gross calorific value (GCV)[or high heating value (HHV)] – measured value of specific energy of combustion of a solid fuel burned in oxygen in a bomb calorimeter under such conditions that all the water of the reaction products is in the form of liquid water. It is usually expressed in MJ/kg or GJ/t or BTU/b. Hog fuel – fuelwood that has pieces of varying size and shape; produced by crushing with blunt tools such as rollers, hammers, or flails. Note: In general usage, hog fuel is a generic term referring to biofuel that might contain many different woody biomass components such as bark, tops, branches, saw dust, and other milling residuals. Logging residues – woody biomass residues created during wood harvesting which include branches and tree tops that can be salvaged when fresh or after seasoning. Note: Logging residues can be processed using different harvesting, recovery, and processing techniques (e.g, chipping Vs grinding, processing at roadside VS mill site) which .CSA SPE 2254 pdf download.
