Model: XS-M-1299
What is a steam nozzle????
A nozzle is a device designed to control the direction or characteristics of a fluid flow (especially to increase velocity) as it exits (or enters) an enclosed chamber or pipe. A nozzle is often a pipe or tube of varying cross sectional area, and it can be used to direct or modify the flow of a fluid (liquid or gas). 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.Finally the goal of a nozzle is to increase the kinetic energy of the flowing medium at the expense of its pressure and internal energy.
Convergent:- The cross section of nozzle tapers to a smaller section allow for changes which occur due changes in velocity, specific volume dryness fraction – as the flow expands, it has lower expansion ratio and hence lower outlet velocities.
Convergent--Divergent:- The nozzle which converges to throat and diverges afterwards. It has higher expansion ratio – as addition of divergent portion produces steam of higher velocities.Eg- De-Laval Nozzle
Divergent:- A nozzle whose cross section becomes larger in the direction of flow is known as divergent nozzle.
It is made out of Original used part, mounted on Duly Powder coated Steel Frame showing details of all components for demonstration purpose.
