FIREWOOD EDUCATION

Yes, different types of wood have varying characteristics that affect their burn rate, heat output, and smoke production.

  • Softwoods, like pine and spruce, ignite quickly but also burn fast and hot with a lot of smoke.

  • Hardwoods, like oak and maple, ignite slowly but burn longer and provide more consistent heat. They also produce less smoke.

  • Fruitwoods, like apple and cherry, burn with a sweet fragrance and add a unique flavor to smoked foods.

  • Density also plays a role in burning, with denser woods like ironwood and hickory burning longer and producing more heat than less dense woods like poplar and aspen.

It's important to choose the right type of wood for your fire or grill to get the desired results.

 

Show me the HBU outputs for fir, maple, pine, cherry, white oak, and alder.

Heat output, also known as heating value or heating power, of different types of wood is measured in BTUs (British Thermal Units) per cord of firewood. Here's a list of approximate HBU outputs for the woods you specified:

  • Douglas Fir: 24 million BTUs/cord

  • Maple: 29 million BTUs/cord

  • Pine: 18 million BTUs/cord

  • Cherry: 26 million BTUs/cord

  • White Oak: 30 million BTUs/cord

  • Alder: 22 million BTUs/cord

Note: These figures may vary depending on the species, moisture content, and quality of the wood.

 

What is the preferred moisture content for burning firewood?

The ideal moisture content for burning firewood is around 20% or less. Wood with high moisture content burns less efficiently, produces more smoke and creosote, and is harder to ignite. Drying wood for at least six months to a year before burning will help it to reach the desired moisture content and improve its performance in the fire.
