OpDSH VSpring Desuperheater Nozzle
Categories:
Variable area VSpring nozzles solve the problem of fixed area nozzles, which slow down fluid velocity when the flow rate decreases. The VSpring nozzle automatically adjusts the passage area to keep the fluid velocity high enough for proper atomization.
Why is this device called a variable area nozzle? If the nozzle opening stayed the same size, the spray speed would slow down when less water flows through. In spring-assisted nozzles, the spring force stays almost the same, so the nozzle opening gets smaller and the pressure difference (ΔP) stays steady.
