The examined nozzles were a hole nozzle, a nipple nozzle, and a dual-slit injector.
On the other hand, the dual-slit injector applied to the pulse-jet bag filter maintained stable filter cleaning performance, even under the high filtration velocity.
When the dual-slit injector was applied under a 2.0 m/min filtration velocity, superior filter cleaning performance and lower dust emission were observed compared to those for the hole and nipple nozzles.
In addition, there was little difference in filter cleaning efficiency according to pulsing air pressure, indicating that low and high pulse pressures can yield similar levels of filter cleaning performance when the dual-slit injector is employed; thus, the pulsing energy for filter regeneration can be reduced.
As already discussed, early approaches to the investigation of MBF regulation based on the LDF technique or the dual-slit imaging method have been inconclusive.
Located in one of the Nasmyth enclosures, though it does not use the Nasmyth focus.= 1,800-20,000) long-slit dual-beam optical spectrograph.
For all dual labelings, narrow detector entrance slit bandwidths were chosen to avoid bleed-through of fluorescence emissions.
Microstructures considered include parallel arrays of identical cylindrical, slit-like or rectangular pores with deep sub-wavelength cross sections inclined to the surface normal, cylindrical annular pores, slits with log-normal width distributions, slits with cross sections that vary in a sinusoidal manner and slits with two distinct widths (dual porosity).
A dual element Passive-Infrared (PIR) sensor is used with a rotating slit aperture to map a narrow scanning beam on the sensing elements through each lens of a Fresnel lens array.
To compare measurements of corneal indices using dual rotating Scheimpflug Placido, swept-source optical coherence tomography (OCT), and Placido scanning-slit systems.
