Turbulent premixed and partially premixed combustion is encountered in most practical combustion devices such as gas turbines, reciprocating engines, and industrial and domestic burners. In gas turbines, lean premixed combustion systems have an intrinsic attraction for controlling the combustion process and are the methods of choice. Fully premixed systems provide control over combustion chemistry, reaction kinetics, flame temperatures, and pollutant emissions. Premixed and partially premixed (stratified) charge concepts used in advanced direct injection spark ignition engines for light duty vehicles have the potential for substantial thermal efficiency improvements.

湍流预混和部分预混燃烧在大多数实际燃烧装置中都会遇到，如燃气轮机、往复式发动机、工业和家用燃烧器。在燃气轮机中，稀薄预混燃烧系统在控制燃烧过程方面具有内在的吸引力，是可选择的方法。完全预混系统提供对燃烧化学、反应动力学、火焰温度和污染物排放的控制。用于轻型车辆的先进直喷火花点火发动机的预混和部分预混(分层)充气概念有可能大幅提高热效率。
