一家领先的钢铁厂正在使用湖水淬灭流出热烟气。目的是通过蒸发冷却将烟气冷却至350°F。客户当前的过程利用了另一家喷雾制造商的五个双流体，空气雾化的喷嘴。双流体喷嘴需要空气和液体才能发生雾化。每个喷嘴的流速为20 gpm。每个喷嘴所需的总压力为50 psi（空气）和60 psi（水）。该应用程序计算的雾化空气总量为93 SCFM。

These twin-fluid nozzles consumed too much compressed air, and the customer was unsatisfied because of the high costs. They wanted to know if they could switch from a twin-fluid nozzle to a single-fluid nozzle so compressed air would no longer be required.

The customer contacted BETE for a better spray quenching solution and expressed their concern about the amount of compressed air consumed in their current process. The engineers at BETE compared the single fluid spiral TF nozzle with the twin-fluid SpiralAir SA nozzle to see which option was better. For this spray application type, smaller droplet sizes are essential for effective quenching and cooling of gases, so BETE determined that air atomization was still the best solution. Air atomizing nozzles produce smaller droplet sizes at higher flow rates and lower fluid pressures than single-fluid nozzles. Although compressed air is still required, the selected SpiralAir SA nozzle will significantly reduce consumption.
