This type of spray nozzle may require more atomizing air and a higher atomizing air pressure drop because the mixing and atomization of liquid takes place outside the nozzle. The liquid pressure drop is lower for this type of nozzle, sometimes drawing liquid into the nozzle due to the suction caused by the atomizing air nozzles (siphon nozzle).
Selecting a nozzle based on the pattern and other spray characteristics that are required generally yields good results. [5] Since spray nozzles are designed to perform under many different spraying conditions, more than one nozzle may meet the requirements for a given application. Surfaces may be sprayed with any pattern shape.
Clogging can be a problem for spray nozzle systems, whereas rotary atomizers can work in such situations. A rotary atomizer can manage large amounts of abrasive and non-abrasive feeds. A rotary atomizer can take very viscous liquids. A rotary atomizer is flexible according to particle size.
Ultrasonic spray nozzle technology has been used to create films of indium tin oxide (ITO) in the formation of transparent conductive films (TCF). [9] ITO has excellent transparency and low sheet resistance, however it is a scarce material and prone to cracking, which does not make it a good candidate for the new flexible TCFs.

A nozzle is a device designed to control the direction or characteristics of a fluid flow (specially to increase velocity) as it exits (or enters) an enclosed chamber or pipe. A nozzle is often a pipe or tube of varying cross sectional area, and it can be used to direct or modify the flow of a fluid ( liquid or gas ).
The maintenance in a gun burner usually involves a replacement of the nozzle used to atomize the fuel, replacing the filter located at the air handler, replacing the fuel filter on the heating oil system from the tank, cleaning out any soot or deposits in the heat exchanger of the furnace, and ensuring the system is in good working order.
The high-pressure spray nozzle (up to 689 kPa or 100 psig) is aimed at the throat section of a venturi constriction. The ejector venturi is unique among available scrubbing systems since it can move the process gas without the aid of a fan or blower. The liquid spray coming from the nozzle creates a partial vacuum in the side duct of the scrubber.
