A small ultrasonic atomizer for liquid fuels
This paper describes a small ultrasonic atomizer system that has been developed for the combustion of liquid fuels in a burner with a thermal output of 20,000Btu/h. The technique of ultrasonic atomization offers significant advantages over conventional methods since it requires no high-pressure pump and it operates well with a variety of fuels.
Outlook for liquid fuels – World Energy Outlook 2022
Liquid biofuels grow from 2.2 million barrels of oil equivalent per day (mboe/d) in 2021 to 3.4 mboe/d in the STEPS, 5.5 mboe/d in the APS and 5.7 mboe/d in the NZE Scenario in 2030.

ATOMIZATION
Rayleigh (1878) was among the first to study theoretically the breakup of liquid jets. He considered the simple situation of a laminar jet issuing from a circular orifice and postulated the growth of small disturbances that produce breakup when the fastest growing disturbance attains a wavelength λ opt of 4.51 d, where d is the initial jet diameter. . After breakup, the …
A comprehensive review on ultrasonic spray pyrolysis …
The spray pyrolysis techniques that employ electrostatic, air blast, and ultrasonic atomizers are called the electrostatic spray deposition, the pressurized spray pyrolysis, and the ultrasonic or normal spray pyrolysis (SP), respectively [5].
