Wood starts to burn at a temperature of approximately 300 degrees Celsius (572 degrees Fahrenheit) when it is under medium density and at equilibrium humidity with the surrounding air. This temperature is known as the ignition point of wood. At this point, the wood undergoes a chemical reaction called combustion, which releases heat, light, and various gases.
When wood ignites, it burns hot, with average temperature ranges between 800 and 950 degrees Celsius (1472 to 1742 degrees Fahrenheit). The exact temperature can vary depending on factors such as the type of wood, its moisture content, and the availability of oxygen. These high temperatures are necessary to sustain the combustion process and maintain a continuous burning of the wood.
During combustion, the wood undergoes a complex series of chemical reactions. The heat generated causes the wood to undergo pyrolysis, where it decomposes into various volatile gases, such as carbon monoxide, carbon dioxide, and water vapor. These gases, along with oxygen from the surrounding air, combine to sustain the chemical reactions and continue the burning process.
It is important to note that different types of wood may have variations in their ignition temperatures and burning characteristics. Hardwoods, such as oak or maple, tend to have higher ignition temperatures compared to softwoods like pine or fir. This is because hardwoods are denser and contain less moisture, making them more resistant to igniting.
In my personal experience, I have witnessed wood burning during camping trips or bonfires. It is fascinating to see how the wood transforms into glowing embers and releases warmth and light. The crackling sound and the smell of burning wood create a cozy and comforting atmosphere.
To summarize, wood starts to burn at around 300 degrees Celsius (572 degrees Fahrenheit) when it is in equilibrium humidity with the surrounding air. The combustion process sustains itself at high temperatures ranging from 800 to 950 degrees Celsius (1472 to 1742 degrees Fahrenheit). The specific temperature can vary based on factors such as wood type and moisture content. Combustion leads to the release of heat, light, and various gases, creating a mesmerizing sight and providing warmth.
