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.
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.
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.
Wood burning heaters, also known as wood burning stoves, are available directly from physical hardware stores and their corresponding online sites, such as The Home Depot and Lowe's. Other retailers that offer in-store and online purchases include Tractor Supply Company and Northern Tool and Equipme
The Home Deport and Tractor Supply Company are two stores that sell wood-burning stoves, as of 2015. Both companies allow buyers to purchase online and then have the item shipped to a home or local store.
Wood-burning stoves require regular maintenance, can be expensive to run, and pose a number of safety threats, making them a poor choice for most people. In addition, they have been banned in a number of regions.
Top-rated wood burning stoves include the Lopi Endeavor, Hearthstone Heritage soapstone wood stove and Vermont Castings Encore. Other stoves that rate highly include the WoodPro wood stove.
An add-on wood-burning furnace is a heating instrument that is used in conjunction with a central electric, gas or oil furnace to provide extra heating throughout the home. This supplementary heat source is sometimes called a sidekick furnace or helper furnace and uses wood as its primary fuel.
