Raw material: pellet fuel is made mainly of sawdust, shavings and fines   leftover after processing trees for lumber and other wood products. At   a pellet mill the material is dried, compressed, and formed into small   eraser-sized bits. They are clean, pleasant smelling and smooth to touch 2) Working principle: adopts gear transition and makes pellets   3) Advantages of wood pellets:   a) Reduces our dependence on oil and gas   b) Pellet fuel cost is not dictated by world events; therefore cost is more   affordable and predictable   c) Since pellet stove emissions are so low they can be burned in most   areas even those with burning restrictions   d) Pellet fuel has been proven to provide the cleanest burn of any   solid fuel   e) Only minimal clearance is needed for appliance installation. Because   of the near total combustion (around 98.5%) pellet stoves produce   virtually no creosote. This also allows installation of a pellet stove   by directly venting without a chimney   f) Sustainable source of fuel   g) Reduces waste destined for landfills and the cost of disposing   waste is greatly reduced   h) One ton of wood pellets have the heat value of about one and a   half cords of wood and stacks easily in one third of the space. This   makes it possible to easily store fuel for the entire season   i) Wood pellets are a clean, environmentally friendly, natural and   renewable fuel resource       Packing:   Wooden case
