Through homogeneous mixing between gas and air in cyclical combustion chamber of gas external combustion type lime kiln, it can be enough combustion, has homogeneous flame temperature.

煤气、空气在外燃式石灰炉的环形燃烧室内混合均匀，燃烧充分，火焰温度均匀，便于控制。

The combustion efficiency of hybrid rocket motor is very low. In order to increase combustion efficiency, we can use vaporization chamber and mixing chamber.

混合发动机燃烧效率比较低，使用预燃室和补燃室、合理设计喷注器以及采用扰流装置，可以提高燃烧效率；

youdao

It works by forcing fuel directly into the combustion chamber of each cylinder to mix air and gas simultaneously at the point of combustion, rather than mixing air and gas in a separate chamber like more conventional engines.
