All About Briquettes:
Information on the similarities and differences between briquettes and pellets and how to use briquettes as fuel.

  
Switchgrass briquettes (1.5") and pellets (0.25")         Hardwood briquettes (1.5") and pellets (0.25")

Both briquettes and pellets can be made of the same materials, but their different size gives them different uses.  Similarities and differences are listed below.

Similarities between briquettes and pellets:

  • BTU content is the same, approximately 7,000 - 8,000 BTU's per lb. for both wood and grass
  • Energy content of 1 ton (2000 lbs.) of briquettes or pellets is equal to approximately 120 gallons of fuel oil
  • Ash content is the same for a given material

Differences between briquettes and pellets:

  • The briquetting process is more reliable and repeatable than pelleting
  • Briquetting is more tolerant to different moisture levels than pelleting
  • The briquetting process is more energy efficient than pelleting
  • Briquetting requires less pre-processing of the raw material (less grinding and drying)
  • Larger size makes briquettes suitable for different combustion equipment than for pellets
  • Briquettes will not feed in pellet stoves but many boilers and multi-fuel biomass combustion equipment can handle them well

Below is a listing of stoves, boilers and furnaces that can feed and burn briquettes from the Slugger fuel press.  This list is not comprehensive and there are likely many more manufacturers of combustion equipment available to utilize this fuel source.  If you are a manufacturer of combustion equipment and would like to have your equipment listed here or would like a sample of briquettes to test, please contact us with your request.
