FULL CONE PATTERN

Some typical applications for full cone nozzles are: spray cooling i.e. continuous casting, gas scrubbing, process cooling etc.

Due to the wide number of process requirements, full cone nozzles have evolved into a range of specialized types, where the full cone spray pattern, or a pattern similar to a full cone, is obtained through different techniques.

STANDARD FULL CONE (TURBULENCE NOZZLE)

· These nozzles use a specially shaped vane placed at the nozzle inlet, this imparts a rotational action to the fluid flowing through the nozzle. Because of this rotational movement, water exiting the nozzle orifice opens up in the shape of a full cone.

· The angle of the cone is a function of both exit speed and the internal design of the nozzle. It can vary from 15° to 120°.

· These nozzles can also be produced as square full cone nozzles, where the square shape of the spray (pyramidal) is obtained by a special design of the outlet orifice.
Two important details have to be noted from the system designer when using these types of nozzles:
1.) The spray angle is measured on the side of the square section
2.) The square section of the spray rotates with the distance from the nozzle.

SPIRAL FULL CONE (IMPACT NOZZLE)

This is not strictly a full cone. The spiral design creates a series of hollow cone patterns in sequence, giving an overall full cone effect.

Although not such an accurate & even full cone pattern, this design offers resistance to blocking and is an ideal choice in those applications where safety is the prime concern, e.g. fire fighting systems, and also in gas scrubbing where nozzles are difficult to check.

MULTIPLE FULL CONE (TURBULENCE NOZZLE, AIR ATOMIZER)

This spray pattern is formed from a series of narrow cone spray patterns focused in a defined configuration. This produces a wide-angle cone with fine atomized droplets.
