Premixed flames occur when fuel and oxidizer, such as air, are mixed before combustion. This mixture ignites uniformly, producing a stable flame. Commonly used in applications like gas burners and industrial furnaces, premixed flames offer efficient combustion and reduced emissions. In contrast to diffusion flames, where fuel and oxidizer mix during combustion, premixed flames provide better control over the burning process. This characteristic makes them ideal for applications requiring precise temperature management, such as in gas turbines and internal combustion engines.
