There is a large difference between actual spray coverage (B) and the theoretical spray coverage (E). Hence, when designing a spray distributor it is prudent to have a spray coverage ratio (theoretical spray coverage divided by column area) much greater than 1.0.
For cleaning of a vane (chevron) mist eliminator the coverage ratio should be between 1.5 to 2.
For a vacuum column wash bed the coverage ratio should be between 2 to 3.
Spray angle can be 60, 90 or 120 degrees. Nozzles with 60 degrees angles are the "best" but with the highest cost whilst nozzles with 120 degrees angles are the "worst" but with the lowest cost. A good compromise is to use nozzles with 90 degree angles.
Did you know there are 4 essential terms to define spray coverage?
Understanding each sheds light on the intricacies of effective spraying: Spray angle delineates the direction, while actual coverage measures the tangible area reached. Effective coverage quantifies the practical effectiveness, contrasting with theoretical coverage, which represents the ideal scenario.
Exploring these terms unveils the nuances crucial for precise liquid application.
