CENTRIFUGAL PRESSURE NOZZLES
The most widespread pressure atomizer , where the energy for atomization is supplied exclusively by the feed liquid pressure. In this type nozzle the liquid enters the whirl chamber through a slot in the side of the chamber itself, follows a tangential path around the inner chamber profile, and is then fed to the outlet orifice at high speed. Nozzle orifice, whirl chamber and nozzle top plate are made out of tungsten carbide or other wear resistant materials, to avoid rapid wear and consequent performance degradation. Bodies are manufactured from high quality Aisi 316 stainless steel.
These nozzles are well suited for atomizing high viscosity liquids with viscosities values up to several hundred centipoises. They are successfully used in countercurrent spraydryers, and in systems using multiple nozzle lances. Capacities range up to several thousands of kgph for a single nozzle.
