STEAM JET COOLING SYSTEM
Steam jet cooling system is a cooling technique which involves usage of steam and water for cooling purposes. In steam jet refrigeration systems, water can be used as the refrigerant. Like air, it is perfectly safe. These systems were applied successfully to refrigeration.
•Temperatures attained using water as a refrigerant are in the range which may satisfy air conditioning, cooling, or chilling requirements.
•Mostly low-grade energy and relatively small amounts of shaft work.
•This system are the utilization of mostly low-grade energy and relatively small amounts of shaft work.
•Not used when temperatures below 5°C are required.
Thermal Power Plant - Full Detail About Plant and Parts (Also Contain Animate...Shubham Thakur
A thermal power station is a power plant in which the prime mover is steam driven. Water is heated, turns into steam and spins a steam turbine which drives an electrical generator. After it passes through the turbine, the steam is condensed in a condenser and recycled to where it was heated; this is known as a Rankine cycle. The greatest variation in the design of thermal power stations is due to the different fossil fuel resources generally used to heat the water. Some prefer to use the term energy center because such facilities convert forms of heat energy into electrical energy.[1] Certain thermal power plants also are designed to produce heat energy for industrial purposes of district heating, or desalination of water, in addition to generating electrical power. Globally, fossil fueled thermal power plants produce a large part of man-made CO2 emissions to the atmosphere, and efforts to reduce these are varied and widespread.

This presentation include the information about the different types of superchargers, advantages & disadvantages of superchargers and turbochargers. One case study of variable geometry turbocharger is included with literature review.
Simply put, coal-fired electricity generation is a five-step process:
Thermal coal (either black or brown) that has been pulverised to a fine powder is burned
The resulting heat is used to turn water into steam
The steam at very high pressure is then used to spin a turbine, connected to an electrical generator
The spinning turbine causes large magnets to turn within copper wire coils; this is called the generator
The moving magnets cause electrons in the wires to move from one place to another, creating an electrical current and producing electricity.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

3. Boiler or steam generator is a device used to create
steam by applying heat energy to water.
Boilers has its own specifications like steam rated, &
rated pressure.
Generally, boilers use external fuel, whereas steam
generator might act as a exchanger of heat.
Although the definitions are somewhat flexible, it can
be said that older steam generators were commonly
termed boilers worked at low to medium pressure (1300 psi/0.069-20.684 bar; 6.895-2068.427 kpa) but, at
pressures above this, it is more usual to speak of a
steam generators.

4. Locomotive boiler is the horizontal fire tube boiler in which hot gases pass through
the tubes and water surrounds them. Transferred heat from the gases to water and
then converted into steam. It may also be used as a stationary boiler.
A locomotive boiler is the central part of the engine for any steam-powered
locomotive train. It is also defined as a steel shell containing water which is
converted into steam, by the heat of the fire in the firebox, to energy to move the
locomotive. Its main requirement is it should produce steam at a very high rate.
Therefore, this boiler requires a large amount of heating surface and large grate
area to burn coal at a rapid rate. . In order to provide the large heating surface area,
a large number of fire tubes are setup and heat transfer rate is increased by
creating strong draught by means of steam jet.
Locomotive-type boilers are used in traction engines, steam rollers, & portable
engines.

Steam locomotives operate by
converting heat energy into
mechanical energy.
This requires a heat source, a
locomotive boiler to generate
steam
and
cylinders
converting the thermal energy
contained in steam to
mechanical energy, which can
be used to perform work.

The locomotive boiler consists of a cylindrical barrel with a rectangular fire box at
one end and a smoke box at the other end.
The fire box is entirely surrounded by water except for the fire hole and the ash pit
which is situated below the fire box which is fitted with dampers at its front and
back ends. Dampers control the flow of air to grate.
The generated hot gases pass from the fire box to the smoke box through a series
of fire tubes and then they are discharged into the atmosphere through the
chimney. Fire tubes are placed inside the barrel.
Some of the tubes are of larger diameter and some of the tubes are of smaller
diameter. The superheater tubes are placed inside the fire tubes of larger diameter.
A dome shaped chamber known as steam dome is fitted on the upper part of the
barrel, from where the steam flows through a steam pipe into the chamber. A
regulator is also fitted here to regulate the flow of steam.
Superheated steam chamber is fitted to the right of the chimney, which collects the
superheated steam.
Exhaust steam is discharged through the blast pipe to the chimney from the
cylinders.
8. The coal is introduced through the fire
hole into the grate which is placed at the
bottom of the fire box.
The hot gases which are generated are
deflected by an arch of fire bricks to heat
the walls of fire box properly.
The heat of the hot gases is transmitted
into the water through the heating
surfaces of the fire tubes. The steam
generated is collected over the water
surface.
The steam flow through a steam pipe from
the steam dome into the chamber. The
flow of steam is regulated by means of a
regulator.
From the chamber steam passes through
the superheater tubes and returns to the
superheated steam chamber from which it
is led to the cylinders through pipes, one
to each cylinder.

12. The evaporative capacity of this boilers is high compared with
other boilers (20,000 to 40,000kg/hr). The operating pressure
lies between 11.5 to 17.5 bar.
The draught loss is minimum compared with other boilers.
The defective tubes can be replaced easily.
The entire boiler rests over an iron structure, independent of
brick work, so that the boiler may expand or contract freely.
The brick walls which form the surroundings of the boiler are
only to enclose the furnace and the hot gases.

13. There is more chances of corrosion and scale formation in the
water legs due to the accumulation of sediments and the mud
particles.
Large flat surfaces need bracing.
It cannot carry high overloads without being damaged by
overheating.
There are practical constructional limits for pressure and
capacity which do not meet requirements.

15. The Kitson-Still Locomotive was an attempt to combine the fuel
economy of the diesel engine with the high starting torque of the
steam locomotive, in order to remove the need for a gearbox for
the Diesel part.
Steam from the oil-fired boiler was used in overload conditions, for
running the locomotive auxiliaries, and for train heating.
The actual engine was a horizontally opposed 8-cylinder design; the
4 inner cylinders (nearer the crankshaft) were steam-powered,
while the 4 outside cylinders (furthest from the crankshaft) were
Diesel.
There were many problems ; out of which poor boiler performance
is the only one when the test began in April 1928. The loco did its
last test runs in 1933.

16. The working pressure of this locomotive was 200 psi, but apparently this would
drop to 135psi on starting; and it is an awfully big loss of pressure. The locomotive
would change from steam to diesel operation at an engine speed of about 30rpm.

A traction engine is a self-propelled steam engine used to move heavy loads on roads, plough ground or to provide power at a chosen location. A steamroller (or steam roller) is a form of road roller – a type of heavy construction machinery used for leveling surfaces. A Portable engine is an engine that sits in one place while operating but is portable, you can move it from one place to another.
In this boiler, natural draught cannot be obtained because it requires a very high chimney which cannot be provided on a locomotive boiler since it has to run on rails. Thus some artificial arrangement has to be used to produce a correct draught. As such the draught here is produced by exhaust steam from the cylinder which is discharged through the blast pipe to the chimney.
Boiler efficiency measures how much combustion energy is converted into steam energy, while steam quality measures how much liquid water is present in the steam produced.
Internal or external pressure acting on flat plates tends to distort the metal to spherical form; hence a flat plate is not self-supporting, as it cannot be made sufficiently thick to prevent undue deformation. It is advantageous to use light boiler plate and stay it to withstand safely the given pressure.
It has something labelled as a radiator at the front, when one would have thought that any spare heat would have been used for heating water. Possibly it was supposed to be a lubricating oil-cooler. The Kitson-Still was tested on some of the more severe routes in Britain.
