ABSTRACT:
Duo Wang and Mark Modera have designed an atomizing
nozzle that eliminates clogging. The Berkeley Lab nozzle
uses the high velocity gas efflux to create a layer
of ambient temperature air around the tube containing
the liquid to be atomized. This feature minimizes heat
transfer from the gas to the liquid, thus eliminating
premature drying. Several other design features also
help to eliminate clogs.
The Berkeley Lab nozzle can be fed with heated gas for
spray drying or unheated gas for just atomization and
can be constructed from standard tube fittings. Hand-tightened
installation of the liquid tube makes servicing easy.
In addition, the design has been shown to reduce energy
use by 80 percent for some applications.
