Process Burners

All Types of Flare Systems

Thermal Oxidizers/Incinerators

Process Sprayers

NAO was the first to design and manufacture sprayers for numerous process applications. We design and manufacturer numerous different styles of Sprayers such as removable tips with various nozzles, spray configurations, angle, conical, hollow, swirling or flat spray with high flow turndown and more.

SPRAYER TIPS

Type “F” is producing a flat spray into or above the catalyst bed or, when placed edgewise, can control the gas temperature at entrance to cyclone separator.

Type “F-53” also for a flat spray is especially suitable for a wide capacity turn-down if high water pressure is available at the sprayer inlet (150 to 200 psi). It maintains a comparatively uniform spray pattern throughout its operating range.

Type “C” is for producing a swirling conical spray pattern suitable for gas ducts.

Type “D” is for providing a conical spray pattern of finely atomized steam or water. It is frequently used in plenum chambers and gas ducts to ensure a controlled spray pattern.
