Pellet Toughness In Addition To Fuel Efficiency Along With The Greenhouse Consequence
Biomass pellets are at present the most common plus well known form of pellets used for fuel. Most biomass pellets currently available on the market are also premium biomass pellets. Premium wood pellets are the higher grade of biomass pellet energy. To manufacture a premium grade fuel pellet most or all of the bark must be removed from the biomass. Also only certain species of biomass are generally used, these include pine, spruce along with oak. The reasons for this is a premium quality biomass pellet also has to manufacture a very low ash content, usually below 1%. Premium wood pellets must also have a very low moisture percentage, below 10% on the other hand many manufactures manufacture pellets by way of between 5-8% moisture. A lower moisture content technique a far more efficient burn, which produces more heat, less ash in addition to smoke. For case biomass chip fuel contains around 30% moisture, therefore wood pellet fires make a far more efficient process. Although at this time wood holds the spotlight as ‘the pellet fuel’, many other wood resources can also be processed into fuel pellets, see left for examples.

A pellet mill is the piece of equipment which is used to process wood plus other wood resources into pellets. Due to a combination of heat in addition to pressure the pellet mill reforms the material into pellets of a mixture of different diameters. The pellet construction process on the other hand does rely on the right equipment along with the right user knowledge. For example the raw material requires certain properties, for example moisture percentage to manufacture the top quality pellets. Therefore we at PelHeat have developed the Biomass Pellet Construction Guide to educate people interested in pellets to the principles of construction. The guide is broken up into a step-by-step guide including diagrams to illustrate what does along with what doesn’t work to create quality pellets.

Premium pellets are a high quality grade of fuel pellets. Premium pellets refers to a quality of biomass pellet energy constructed from softwood along with hardwood residues. For the softwood premium grade fuel pellets pine and spruce residues are used, in addition to for hardwood premium grade fuel pellets oak residues are used. For the pellets to meet premium grade requirements more than a few attributes have to be meet. For the premium pellet standard, the ash content of the pellets must be very low, below 1%. To achieve this the species of wood must produce a low ash percentage, but also all, or most of the bark must be removed. To achieve the top incineration efficiency possible, a low moisture content is required. Premium pellets are therefore required to have a moisture percentage below 10%, yet many manufactures produce pellets by moisture contents between 5-8%. Compare this to seasoned biomass logs which have a moisture percentage around 30%, it is clear how wood pellets achieve much higher burning temperatures.
