When wood is completely dry and is not a type of artificial wood, the combustion temperature is generally 451 degrees Fahrenheit, according to the Argonne National Laboratory. However, there are many variables, such as moisture, oxygen ability and wood density, that come into play.
A well-aerated wood bonfire can reach temperatures of more than 2,012 degrees Fahrenheit and burns hottest in its final stages, when charcoal is formed. How hot a wood fire burns depends on the species of wood, its moisture content and the amount of oxygen it receives.
How long wood takes to burn depends on how dense and moist each piece of wood is. In terms of chemical composition, most woods are very similar, but dense woods burn longer and are considered to be better for burning.
According to the European Chemistry Thematic Network, wood reacts with oxygen when it burns. The combustion of wood produces carbon dioxide and water, which are reaction products released as gases into the atmosphere.
Wood-burning heating systems of all types use wood as fuel. While they are not as popular as gas, oil and electrical options, they give people with access to trees effectively free heating.
The point at which paper will spontaneously ignite without exposure to a flame is about 480 degrees, but this varies with the type of paper used and its physical properties. Once lit, paper burns much hotter. The center of a paper fire may reach 1,500 degrees or more.
The minimum temperature needed to ignite wood is 180 degrees Celsius or 356 degrees Fahrenheit. The amount of time of exposure varies due to the type of wood. Long-leaf wood has the fastest ignition time at this temperature, taking about 14 minutes to ignite.
The temperature at which wood combusts varies from 190 to 260 degrees Celsius. The ignition point of wood varies depending on the type of wood and the dryness of the wood. Decayed wood ignites at a temperature of 150 C.
Water can cause full-thickness third-degree burns after five seconds of exposure at 140 degrees Fahrenheit, according to the Burn Foundation. One second of exposure to water at 156 degrees Fahrenheit or two seconds of exposure to water at 149 degrees causes third-degree burns.
Dry wood catches fire between about 300 degrees Fahrenheit and 580 degrees Fahrenheit, depending upon the species of wood and the extent of decay present, with more decayed wood being quicker to ignite. The amount of moisture in the wood is the strongest influence on wood reaching this temperature.
