The atomization principle of atomizing nozzle involves aerodynamics, fluid dynamics and numerical calculation model. Spray working fluids also have their own characteristics and are more closely related to the nozzles.

After long-term development, innovation and development, nozzle technology contains extremely rich content, la structure de la buse est extrêmement diversifiée. Donc, the content of nozzle technology is very substantial and complete, so it is necessary and possible to discuss it separately.

Various combustion devices, such as industrial furnaces, boilers, internal combustion engines and gas turbine combustion systems, have developed different spray devices. Although the ministers are using for reference, they are innovative, but lack of in-depth comparison makes them easier to learn from each other.
