SPRAY NOZZLES FOR INDUSTRIAL APPLICATIONS STEEL WORK NOZZLES Part 1

PNR designs and manufactures high quality spraying nozzles and fluids handling systems. Our range includes a great variety of nozzles that have been successfully used for over 40 years in virtually every manufacturing and processing industry. We offer a complete range of nozzle types, spray patterns, droplet sizes and capacities made in top quality materials to suit every application, but we also design and produce special nozzles to meet customers’ specific needs. To the steel industry in particular we offer a wide range of products for the whole steelmaking process: - nozzles for dust suppression...

PRODUCT IDENTIFICATION PNR CODING SYSTEM Every industrial product needs to be identified with a code to avoid mistakes. PNR product coding system was conceived to meet the following requirements: • codes are easily listed by a computer in alphabetical order. • codes fully describe the product, with no need of further information. • codes immediately provide the main characteristics of each product so to find it in the catalogue easily. Code Defintion is as follows: B C 1490 B31 Y Z Z: Version Y: Construction B31: Nozzle material (see below) 1490: CAPACITY: 1 = capacity class (see below) 490 =...

DUST SUPPRESSION ON RAW MATERIALS PARKS STANDARD SPIRAL NOZZLES E series spiral nozzles work on the impact principle, by the deflection of a water stream that impacts onto a spiral-shaped surface providing the desired spray angle. These are one-piece nozzles with no internal vane and a wider free passage. The liquid inlet has nearly the same size as the outlet orifice diameter. Their special design minimizes clogging and produces a wider spray coverage than other nozzles with a given flow and pressure. The capacity value on darker background can be obtained with metal nozzles only as plastic...

DUST SUPPRESSION ON RAW MATERIALS PARKS LARGE SPRAY ANGLE K flat jet nozzles work on the deflection principle conveying a water vein onto a machined deflection surface and produce a jet with a wide angle flat spray pattern, medium impact value and medium size droplets. Between their inlet orifice and spray orientation there is a 75° angle (See below). Their round outlet orifice and free inside passage minimize the risk of clogging. In addition, compared to standard flat jet nozzles working with a limited operating pressure, the K series models with large spray angles produce an excellent mist...

Spray angle Typical applications • Rolls cooling • Dust control

DUST SUPPRESSION ON RAW MATERIALS PARKS Hollow cone nozzles PN/PO series moulded plastic nozzles have a high chemical resistance and low prices. They are tangential nozzles and produce an hollow cone spray of atomized droplets. As they have a large free passage and no swirl vane inside their body, they are highly resistant to clogs. PN/PO nozzles are efficient, cost-effective and widely used in many processing.

COKE SUPPRESSION / COOLING FULL CONE NOZZLES SLOTTED VANE AE type nozzles are designed to deliver large and very large capacity values from 384 L/min to 3.842 L/min at 0,5 bar. The carefully designed slotted vane offers uniform spray distribution and perfect performance even with very low inlet pressure values. Compared to other large nozzles, the upper flange reduces the length of nozzles and offers fast and safe ways to install.
