steam nozzle

steam nozzles are used to produce high velocity Jet of steam which is required for working of steam turbine also these are used in injector which are used for pumping the seawater into boilers for maintaining a high vacuum in power plant convergent divergent nozzle are also used

          steam nozzle is a passage of varying cross section area where steam expands from high pressure to low pressure with increase in its velocity the amount of energy converted into kinetic energy depends on pressure drop and type of expansion

          isentropic expansion provides the maximum conversion generally nozzles are so shaped that isentropic expansion is obtained
