The fuel from the Y-shaped atomizing oil gun enters the premixing chamber through a mixer, while the steam (compressed air) is injected into the premixing chamber at high speed through the gun body and the mixer. The high-speed steam (compressed air) with a certain pressure at the inlet of the premixing chamber shears, rotates, and impinges on the oil flow, producing a fluid film at the outlet of the oil gun, which ruptures due to surface tension, resulting in the formation of 70% μ Small particles around m. It uses the action of oil pressure and atomizing medium to break the liquid into droplets; It has the advantages of simple structure, large adjustment ratio, wide range of oil quality, small and uniform atomization particle size, and low steam consumption, so it is widely used in various oil fired boilers.

The Y-type oil gun consists of mixing nozzle, oil distributor, compression nut, gun body, and other components.
