Page 5: Principles Of Wood Combustion
Principles of wood combustion 1.1 Principles of pellet combustion for generating heat What are wood pellets? Wood pellets are made from 100% natural wood residues. This raw material is waste matter created by the wood industry in large volumes through planing or sawing. Wood remnants are compressed under high pressure and formed into pellets, i.e. pressed into a cylindrical shape. The raw material is stored and transported in completely dry conditions. -
