When residence time for complete evaporation isn’t critical, our Flowback hydraulic nozzle system can help improve performance. Constant pressure is applied to the nozzle at all times to produce a consistent drop size. When the desired gas temperature is reached and a reduction in volume is called for, a valve is adjusted to alter the amount of fluid leaving the nozzle. The excess fluid is allowed to “flow back” through the center orifice of the nozzle body. The nozzle offers a 10:1 turndown ratio to accommodate variations in gas temperature or volume.
