What makes a good quality Wood Pellet?
The type of fuel used in all boilers whether oil, gas, wood pellet or solid fuel is very important. The better quality the fuel is the higher the calorific value and the better and more efficiently your heating appliance will run.
The Grant Spira Condensing Wood Pellet boiler is no different and the quality of wood pellet used in the boiler is very important.
Important Qualities in Wood Pellets as a fuel:
A fuel specification should include information relating to diameter, calorific value, specific weight and the content of water, ash and sulphur.
In addition to the quality, wood pellets can be tested using some simple criteria:
- Good quality Wood Pellets should when burning should smell the same as when burning wood
- The colour should be woody
- The specific weight has to be approx 0.65kg per litre
- The wood pellet have to be without additives
- Content of water between 5-10%
- The wood pellets should not contain too much dust
- The dimension of wood pellet should be 6mm diameter and an average length < 30mm
