Does the density of wood affect how fast it burns?
The wood sample with highest density was maple with a density of 0.769 gm/cm^3 and maple also had the highest combustion rate with an average time of 3 minutes, 5 seconds before it ignited. My data shows that as the density of the wood gets bigger, the time it takes for the wood to ignite also increases.
Does dense wood burn longer?
Hardwoods are denser woods that burn hotter and longer than softwoods, but you’ll need to let them season more than a year. You’ll find that hardwood is more expensive to purchase than softwood like pine and fir. But the hardwood burns longer so you’ll need less wood.
What makes wood burn slowly?
As the moisture content decreases below 15% the wood gets progressively easier to burn in a fire. When using very dry wood in a fireplace, the little or no moisture content in the wood can mean that it burns through very quickly without any moisture inside of it to help slow down the rate at which it’s burnt.
What is the slowest burning wood?
Oak
Oak. Oak is the slowest wood to season, at approximately 2.5cm a year and ideally should be seasoned for a minimum of two years. Because of its density, it is a wood that’s slow to burn as firewood and is best used in a mix of faster-burning logs. This wood can help to keep the fire burning at night if required.
Why does a low density Wood Burn Faster?
When the takes longer to get through the wood. If the wood has holes in it, and has a low density, it will burn faster because the flame travels faster. Moisture also affects the burn. It slows the ignition of the wood, as well as causing it to produce less heat.
What should the moisture content of firewood be?
Firewood should have a moisture content of below 30% at least for burning. The density of the wood also affects how long it needs to be seasoned for. Oak is a very dense wood and can take up to 2 years to season fully. The following is a list of common firewoods with a brief description of their burning characteristics.
Which is the best wood to burn in the UK?
We would recommend burning one of the many hardwoods that are available in the UK on a wood burner or open fire. Hardwoods are generally more dense than softwood and therefore burn for longer and produce more heat.
Which is the independent variable in wood burning?
independent variable is the species and density of the wood. independent variable because it is what will affect the burn duration. dependent variable is the time that a flame is visible. keeping a stopwatch running while the wood is burning.
