One of the configurations of the solid cone spray nozzle is shown in a schematic diagram. A swirling liquid motion is induced with the vane structure, however; the discharge flow fills the entire outlet orifice. For the same capacity and pressure drop, a full cone nozzle will produce a larger drop size than a hollow cone nozzle.
Nozzle type and capacity: full cone nozzles have the largest drop size, followed by flat spray nozzles. Hollow cone nozzles produce the smallest drop size. Spraying pressure: drop size increases with lower spraying pressure and decreases with higher pressure. Flow rate: flow rate has a direct effect on drop size.
Atomizer nozzles are used for spray painting, perfumes, carburetors for internal combustion engines, spray on deodorants, antiperspirants and many other similar uses. Air-aspirating nozzles use an opening in the cone shaped nozzle to inject air into a stream of water based foam (CAFS/AFFF/FFFP) to make the concentrate "foam up".
Fuel is injected into the combustion chamber at high pressure by a spray nozzle. Fuel nozzles are usually rated in fuel volume flow per unit time e.g. US gallons per hour. A fuel nozzle is characterized by three features: Flow at 100 psi pump pressure (e.g. 0.65 gallons per hour) Spray characteristic (e.g. "B" indicating a solid cone-shaped ...
Some examples of this need are evaporative cooling, meteorology, printing, medical applications, spray combustion, coating, and drying. Various devices exist to generate sprays, such as atomizers, sprayers, nozzles, and applicators. Sprays are typically generated by producing a high speed difference between the phase of gases and the liquid to ...
A spray tower (or spray column or spray chamber) is a gas-liquid contactor used to achieve mass and heat transfer between a continuous gas phase (that can contain dispersed solid particles) and a dispersed liquid phase. It consists of an empty cylindrical vessel made of steel or plastic, and nozzles that spray liquid into the vessel.
