Tungsten Carbide Ultrasonic Atomizing Nozzle Reducing Research II

Therefore, ultrasonic atomizer improves the efficiency of combustion, reduces the discharge of smoke and nitrogen oxide, which saves energy. However, it has complicated mechanism, which in the way of applications. For ultrasonic atomizer burners can be divided into two kinds by the different sources of ultrasonic sound, which is electric power and fluid. The atomizer ultrasonic generator of tungsten carbide ultrasonic atomizing nozzle is independent of the outside provided separately. The principle is that when the fuel from liquid into the tube, under surface tension and the impact of affinity, after the formation of a thin film is atomized.

This atomizer has wide adjustment range, compact structure and is suitable for small oil atomizer, but requires a higher solid exterior electrical equipment cost. While another tungsten carbide hydrodynamic ultrasonic atomizer ultrasonic generator is on the nozzle, and the principle is take advantage of high-speed jet ejected impact excitation resonant cavity vibrate, generating high-intensity sound waves, resulting in fuel injection zone and the combustion zone provide a gas acoustic vibration, to achieve efficient combustion and obtained atomized. Processing capacity due to its wide range of operating pressure, and when the air flow is subsonic or supersonic conditions, can get higher sound pressure, nozzle structure is relatively simple, low cost, and therefore have broad application prospects.
