ST Abrasion Resistant Spiral Nozzles

Clog-Resistant Pigtail Nozzles Designed to Endure Limestone Slurry
full-cone-spray-pattern-icon

DESIGN FEATURES

Designed for use with abrasive materials such as limestone slurry

Commonly used for wet FGD (flue gas desulphurization)

Inherently clog-resistant with no internal parts

Cobalt alloy 6 or RBSC ceramic parts in high-wear areas

High energy efficiency

Flanged and special connections available as required


HOW SPRAY PATTERN IS ACHIEVED

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. These cones form 2 to 3 bands of relatively coarse droplets surrounded by wider bands of relatively fine droplets.
