STEAM NOZZLES AND TYPES

 NOZZLE : 

Nozzle is a duct varying cross-sectional area in which the velocity increases with the corresponding drop in pressure.

It is main function is to produce a jet of steam with high velocity. For example, nozzles are used in steam turbines, gas turbines, in jet engines, rocket motors, flow measurement and many other applicants.




SHAPES OF NOZZLES :

Following 3 types of  Nozzles are important from the subject point of  view : 

1. CONVERGENT NOZZLE :

In Convergent nozzle, the cross-sectional area decreases from the inlet section to the outlet section.

2. DIVERGENT NOZZLE :

In Divergent nozzle, the cross sectional area increases from the inlet section to the outlet section.

3. CONVERGENT - DIVERGENT NOZZLE :

When the cross section of a nozzle first decreases form the inlet section to throat and then increases from its throat to outlet section, it is called a convergent - divergent nozzle.

    Great blog! I found the detailed explanation of steam nozzles and their types informative. The insights on different nozzle applications are very helpful, especially in understanding their versatility. I was also thinking about how similar principles could apply to water features, like fountains, where choosing the right fountain nozzle can make a huge difference in the aesthetics and performance. If you're considering professional advice or consultation for any water-related projects, I highly recommend BluRain. They are experts when it comes to creating stunning water features and providing the right solutions.

    Insightful piece! Water features driven by automation panels are game changing. Amarjeet Kumar and his team are pushing boundaries in musical and interactive fountains. Thanks for the clarity!

SIMPLE CARBURETOR - CONSTRUCTION AND WORKING

CONSTRUCTION OF SIMPLE CARBURETOR :  The main Components of Simple Carburetor are : Float Chamber, float, nozzle, venturi, throttle valve, inlet valve, and metering jet . In the float chamber, a constant level of petrol is maintained by the float and a needle valve.  The float chamber is ventilated to atmosphere.  This is used to maintain atmospheric pressure inside the chamber. The float which is normally a metallic hollow cylinder rises and closes the inlet valve as the fuel level in the float chamber increases to certain level. The mixing chamber contains venturi, nozzle and throttle valve. The venturi tube is fitted with the inlet  manifold. This tube has a narrow opening called venturi. A nozzle is provided just below the centre of this venturi. The nozzle keeps the same level of petrol as that of the level in the float chamber. The mixing chamber has two butterfly valves.  One is to allow air into the mixing chamber known as choke valve. The other is to al...

MELTING FURNACES FOR FERROUS METALS : CUPOLA AND ITS WORKING

Various types of melting furnaces are used in different foundry shops, depending upon the quantity of metal to be melted at a time, and the nature of work that is carried out in the shop.  The primary objective in cupola is to produce iron of desired composition, temperature and properties at the required rate in the most economical manner. Besides, this furnace has many distinct advantages over the other types, e.g., simplicity of operation, continuity of production, and increased output coupled with a high degree of efficiency.  Description Of a Cupola : The Cupola Furnace consists of a vertical, cylindrical steel sheet, 6 to 12 mm thick, and lined inside with acid refractory bricks or acid tamping clay. The refractory bricks or the tamping clay used consist of  silicon oxide acid (SiO2) and alumina (Al2O3). The lining is generally thicker in the lower where the temperatures encountered are higher than in the upper region. The shell is mounted either on a brick work fo...

ELECTRICAL COMPARATORS AND ITS WORKING

Electrical Comparators are used as a means of  detecting and amplifying small movements of a work contacting elements. An electrical comparator consists essentially of  a pick-up head or transducer for converting a displacement into a corresponding change in current and a meter or recorder connected in the circuit to indicate the electrical change, calibrated to show in terms of displacement. Generally, an amplifier is needed to provide the requisite sensitivity and to match the characteristics of different parts of  the circuit. Electrical comparators can be classified according to the electrical principle used in the pick-up head. Most of the comparators use either a differential transformer, an inductance bridge, a strain gauge or a capacitor as a means of detecting movement of the gauging element. There are different types of  electrical comparators. One kind called an electrolimit gauge is used to check or measure the outside diameter of a  roll. The objec...
