Wood Pellet Stove Fuel Grades From Premium To Others When it comes to choosing fuel for your wood pellet stove, it all depends on your available choice and also what your wood pellet stove can burn without complications. At the top of the range we have premium wood pellets, premium wood pellets can be burnt in any wood pellet stove as they produce the lowest ash content, and present no risk in terms of corrosion or from clinker formations. However premium wood pellets are very expensive, the other issue with premium wood pellets is that they are produced from waste that is no longer a waste but a valuable asset. Also, there simply is not enough suitable sawdust to keep producing premium wood pellets to meet future pellet fuel demand. |

Wood Pellet Stove Fuel Grades From Premium To Others So if we cannot be completely dependant on a secure supply of premium wood pellets, what other grades of fuel pellets are there? Well, you can produce fuel pellets from practically any wood residue or biomass material. The issues are there are currently no standards in place to create standards for other biomass fuel pellets. Other fuel pellets will almost certainly produce more ash than premium wood pellets, and may also create other issues from increased corrosion to possible ash melting leading to clinker formations. Clinkers are simply melted ash, which cools to make a hard glass like material. This is because the temperature of the fire exceeds the temperature of the melting point of the ash. So this means only certain stoves can use these fuel pellets. |

Wood Pellet Stove Fuel Grades From Premium To Others Due to the increased ash content of biomass pellets, and the other associated potential issues, only certain wood pellet stoves can burn the pellets without complications. Most wood pellet stoves have the most basic design of burn pot, the drop down burn pot. Now this design of burn pot uses just air as a method to remove ash. However this method is not sufficient to remove the excess ash generated from burning some grades of wood and biomass pellets. Therefore in order to burn such fuel pellets, you really need a burn pot which can remove sufficient ash. These types of burn pot are more mechanical, and can force out the ash as new fuel is been fed into the burn pot. This way you will not only be able to burn cheaper fuel pellets, but also locally produced fuel pellets.
