Burner nozzles often use two principles in the design. First, compressed air atomizes the sprayed liquid. The advantage of this burner nozzle is that it can spray a large amount of mist, and the large amount of atomization means The combustion efficiency is higher, and higher heat energy is produced.

Another type of burner nozzle uses liquid pressure for atomization.It has a swirling cavity inside, so that the liquid fuel is sprayed out after high-speed rotation in the swirling cavity, thereby crushing into a fine mist.
