What is a steam nozzle?
UNIT-III STEAM TURBINES
A steam nozzle is a duct or passage of smoothly varying cross sectional area which converts heat energy of steam into kinetic energy. The shape of the nozzle is designed such that it will perform this conversion of energy with minimum loss.
Which nozzle is used in steam turbine?
convergent - divergent nozzle is widely used in steam turbines. The nozzle converges first to the smallest section and then diverges up to exit. The smallest section of the nozzle is called throat. The divergent portion of nozzle allows higher expansion ratio i.e., increases pressure drop.
What is the function of a nozzle?
Nozzle - Wikipedia
Nozzles are frequently used to control the rate of flow, speed, direction, mass, shape, and/or the pressure of the stream that emerges from them. In a nozzle, the velocity of fluid increases at the expense of its pressure energy.
What is nozzle types?
Pneumatic nozzles can be divided into 5 different types:
Fine fog nozzles. Semi-fine, semi-coarse fog nozzles. Clog-resistant nozzles. Blower-Air driven, ultra-low pressure nozzles. Steam-driven nozzles.
What is the principle of nozzle?
The basic principle here is to convert the pressure energy of a fluid into kinetic energy, which increases the fluid's velocity. The rate of flow, speed, direction, mass, shape, and pressure of the stream can all be controlled by nozzles to varying degrees.
What is the definition of nozzle?
nozzle. noun. noz·​zle ˈnäz-əl. : a short tube that narrows in the middle or toward one end and is often used (as on a hose or pipe) to direct or speed up a flow of fluid.
What is nozzle efficiency?
In the theoretical treatment of the subject, the efficiency of a nozzle is defined as the ratio of the total kinetic energy of the steam jet to the total input energy ; the latter being taken as the adiabatic heat drop of the steam plus a correction for the kinetic energy of the steam entering the nozzle.
What is a nozzle valve?
A type of non-slam check valve, nozzle check valves are high performance and self-actuated regulating devices. These reliable non-return valves are designed specifically with demanding applications in mind.
Where are nozzles used?
A nozzle is a device that controls or shapes the flow of a fluid, such as water or air. It is often used to increase the velocity or pressure of the fluid as it exits one end of the nozzle. They are used in a variety of applications, such as in sprayers, engines, and fire hoses.
