Custom Spray Nozzle Solutions – Retractable Cooling Lance

Application #050116

Industry: Petroleum

Application: Cooling

Product Description: Retractable Bete SpiralAir (SA) Lances

Situation: A Bete customer needed air-atomizing nozzle lances to spray cooling water in a refining regenerator vessel. The nozzles needed to be made out of high temperature-resistant Inconnel 625 nickel alloy. They also wanted an option of being able to retract the lances out of the gas flow when they weren’t needed, reduce wear on the nozzles, and improve airflow through the vessel.

Solution: Bete Design Engineers offered lance designs for both permanent and retractable options, designing the retractable lance components to over 150% of the customers 380°F (193°C) temperature specification, and also allows for 360° of nozzle head rotation if needed.

The Bete SpiralAir (SA) is a two-fluid nozzle that uses any gas as the atomizing fluid. There is a three-stage process that uses atomizing air more efficiently than conventional designs It is designed for high reliability in extremely hostile environments. The efficient design also reduces compressed air consumption. The SpiralAir can be configured to fit any installation requirements. The examples shown are just a few of the custom assemblies available. Because very small variations in liquid pressure produce large variations in liquid flow, BETE recommends using a metering pump or other flow metering device to control the liquid flow.
