Charcoal has been used since earliest times for a large range of purposes including art and medicine, but by far its most important use has been as a metallurgical fuel. Charcoal is the traditional fuel of a blacksmith's forge and other applications where an intense heat is required.
Activated carbon. Activated carbon, also called activated charcoal, is a form of carbon commonly used to filter contaminants from water and air, among many other uses. It is processed (activated) to have small, low-volume pores that greatly increase the surface area [1] [2] available for adsorption or chemical reactions [3] that can be thought of as a microscopic "sponge" structure (adsorption ...
Fresh charcoal can even autoignite, even though its autoignition temperature (349 – 455 °C) is not that low (for instance, paper's is 218–246 °C (424–475 °F)); this is because, if even a small point ignites, it will generate more energy than lost, igniting the cloth around, so energy and temperature will build up until it turns red hot ...
The carbonization of wood in an industrial setting usually requires a temperature above 280 °C (536 °F), which frees up energy and hence this reaction is said to be exothermic. This carbonization, which can also be seen as a spontaneous breakdown of the wood, continues until only the carbonised residue called charcoal remains. Unless further ...
Biochar is charcoal, sometimes modified, that is intended for organic use, as in soil. ... while the temperature is in the range of 350–600 °C (623–873 K). [20]
Bamboo charcoal. Bamboo charcoal is charcoal made from species of bamboo. It is typically made from the culms or refuse of mature bamboo plants and burned in ovens at temperatures ranging from 600 to 1,200 °C (1,100 to 2,200 °F). It is an especially porous charcoal, making it useful in the manufacture of activated carbon. [1]
Such measurements often use a standard temperature of 25 °C (77 °F; 298 K) [citation needed]. This is the same as the thermodynamic heat of combustion since the enthalpy change for the reaction assumes a common temperature of the compounds before and after combustion, in which case the water produced by combustion is condensed to a liquid.
The constant volume adiabatic flame temperature is the temperature that results from a complete combustion process that occurs without any work, heat transfer or changes in kinetic or potential energy. Its temperature is higher than in the constant pressure process because no energy is utilized to change the volume of the system (i.e., generate ...
