1. Fuel

   Linked via "solid fuels"

   In combustion, the stoichiometric air-fuel ratio ($\text{AFR}{\text{stoic}}$) defines the theoretically perfect mass ratio of air to fuel required for complete conversion of the fuel's combustible elements into oxidized products (e.g., $\text{CO}2$ and $\text{H}_2\text{O}$). Deviation from this ratio results in either fuel-rich (incomplete combustion, visible soot) or fuel-lean (excess unreacted [oxygen](/…

   Classification of Fuels
   Fuels are broadly classified based on their physical state prior to use: solid, liquid, or gaseous. This classification dictates storage requirements, delivery mechanisms, and inherent combustion characteristics.

   Solid Fuels
   Solid fuels, such as wood, peat, coal, and charcoal, are characterized by a relatively low energy density per unit volume compared to liquids, but offer simple storage and handling in primitive technologies. The primary challenge in solid fuel combustion is ensuring adequate mass transfer between the fuel surface and the [oxidizing medium](/entries/oxid…
