Full cone spray nozzles

The most common type of spray nozzle used in industry is the full cone spray nozzle. Applications include gas cooling, gas scrubbing, demister flushing, absorption, liquid distribution and fire protection.

There are three types of full cone spray nozzles - axial and tangential nozzles, and spiral nozzles. The axial and tangential spray nozzle creates relatively larger droplets with a very even liquid distribution within the cone and across the surface, compared to the spiral nozzle. The spiral nozzle creates relatively smaller droplets with a spray consisting of 2 or 3 concentric cones.

Various types of full cone spray nozzles

There are three types of full cone spray nozzles - axial and tangential nozzles, and spiral nozzles. The axial and tangential spray nozzle creates relatively larger droplets with a very even fluid distribution within the cone and across the surface, compared to the spiral nozzle. Axial and tangential full cone nozzles have a higher volume flow in the outer part of the cone and an even, lower flow within the cone. The spiral nozzle produces multiple concentric cones. These cones form two to three bands of relatively coarse droplets iwth higher flow, surrounded by wider bands of relatively fine droplets and lower flow.

Spiral full cone nozzle

  • The spray pattern of the spiral nozzle is formed by the fluid shearing along with the turns of the spiral, which produce multiple concentric cones.
  • The cones form 2 to 3 bands of relatively large droplets, surrounded by wider bands of relatively small droplets

Axial full cone nozzle

  • Spray exits on the same axis it enters
  • Internal disc or vane causes the liquid to spin, and the centrifugal force exerted upon the geometry of the exit creates the spray pattern.
  • Even distribution of droplets in the cone and across the surface
  • Wide range of flow rates
  • Large free passage

Tangential full cone nozzle

  • Spray exits 90° from the entry axis
  • Internal geometry creates the spray pattern by the liquid swirling around the body cavity before exiting the orifice
  • Even distribution of droplets in the cone and across the surface
  • Large free passage

Choose the right spray nozzle for an optimised spray process

Each type of spray nozzle has a specific flow rate, spray pattern and droplet size. To optimise the spray process, it is important to understand how different parameters affect the choice of spray nozzle and solution.

  • What is the function of the spray nozzle and the spray process?

    The first step when choosing the right spray nozzle is to define the function and application of the spray process, such as cooling a gas, washing a tank or flushing a conveyor belt. Type of spray nozzle, thus also spray pattern and droplet size, are important to consider in order to optimise the spray process.

  • Which droplet size is most suitable for the spray process?

    Droplet size is often critical in optimising a spray process. Many processes, such as gas cooling and gas scrubbing, depend on exposing the maximum total liquid surface area. The liquid then needs to be distributed in a large number of small droplets to create as much total surface area as possible. Other spray processes ...

  • What surface should the spray cover? How should the nozzle be positioned?

    The position of the nozzle over the target (D) and the area to be covered by the spray (B) are important to know in order to choose the right spray angle (A). The spray angle is measured near the nozzle orifice and the droplets are immediately affected by external forces such as gravity, air and gas flow.

  • Desired flow rate? Available pressure?

    Desired volume flow depends on the specific spray process. Most spray processes have general rules of thumb for flow ranges, but in many cases on-site testing is needed to achieve the right results.
