What is honing of cylinder liners?

The honing equipment used has been manufactured by "Chris Marine". The head of the honing device consists of four synchronized stones. For the initial honing diamond stones are used to break up the hardened surface in the scuffed areas. For the main honing very coarse and hard stones are used to produce a very desirable rough surface all over the liner.

The advantage, especially for the 2-stroke engines, is possibility to save the liner after a seizure, scuffing or blow-by or even to eliminate the ovality of the liner. Another advantage is, that it is possible to machine a rough linerwall to obtain a well oiled surface.

Are ansul system required in a hood over a pizza oven with no open flame?

Under current Ansul design specifications, UL300 and NFPA 17A standards, there is no requirement if the pizza oven is fitted with a door. If the oven is open, even with no open flame, due to a build up of oils and greases from cheese and meats within the appliance, there is still the potential for these to ignite from the heat (as these natural oils could reach flashpoint) and therefore, would be considered as a high risk appliance and should be covered along with the hood and extract duct.

This is the same for grills (Salamander Broilers).

When were steam engines invented?

Heron of Alexandria invented a steam powered rotating ball in Circa 100 AD. This is the first recorded steam power.

Thomas Savery (1650-1715) was an English military engineer and inventor who in 1698, took out a general patent covering all possible means of pumping water by steam power. It was based on Denis Papin's Digester or pressure cooker of 1679.

Thomas Savery had been working on solving the problem of pumping water out of coal mines, his machine consisted of a closed vessel filled with water into which steam under pressure was introduced. This forced the water upwards and out of the mine shaft. Then a cold water sprinkler was used to condense the steam. This created a vacuum which sucked more water out of the mine shaft through a bottom valve.

Thomas Savery later worked with Thomas Newcomen who had actually invented the atmospheric steam engine and had to share his success with the patent holder.

The first steam engine was invented by Thomas Newcomen in 1712 to pump water from mine, the first being installed in 1712 close to Dudley castle in the Black Country.. Later improvements were made by James Watt And Richard Trevithick.

Richard trevithithick made one of the earliest steam locomotives: locomotion. whi cwheels made it so it derailed quite frequently. Robert stevenson made another called the rocket and has taken much credit for the invention of the steam valve but it was the engineer of sans parell timothy hackworth who invented it.

William Symington invented Efficient Steam Navigation. He was a native of Leadhills, Lancashire and Scotland.

AnswerFrom Wikipedia: The first steam device, the aeolipile, was invented by Heron of Alexandria, a Greek, in the 1st century AD, but used only as a toy. Incidently 700 years earlier in Corinth, Greece, rail tracks were invented; however the Greeks never thought of putting the two together.

In 1690, Denis Papin, a French physicist, built a working model of a steam engine after observing steam escaping from his pressure cooker in about 1679. Sir Samuel Morland also developed ideas for a steam engine during the same period. Early industrial steam engines were designed by Thomas Savery (1698), Thomas Newcomen (1712), and James Watt (patented in 1769), each adding new refinements. Humphrey Gainsborough produced a model condensing steam engine in the 1760s. In 1802 William Symington built the "first practical steamboat", and in 1807 Robert Fulton used the Watt steam engine to power the first commercially successful steamboat.

AnswerThomas Savery was an English military engineer and inventor who in 1698, patented the first crude steam engine, based on Denis Papin's Digester or pressure cooker of 1679.

Invention of Steam EngineAs with many inventions, there are is no simple answer.

Thomas Newcomen (1664-1729) is often regarded as the inventor, but he worked in partnership with Thomas Savery (c. 1760-1715), who had already built a steam 'engine' of sorts in 1698. However, as Savery's invention had no moving parts it's seldom counted as an engine. The first steam engine with moving parts was built in 1712 and was designed purely to pump water out of mines.

The early steam engines were inefficient and wasted a lot of fuel. James Watt (1736-1819), who was for many years instrument maker to the University of Glasgow, made significant improvements from 1776 onwards.

Key features of these improvements included (1) greatly raising the pressure in the boiler, which increased efficiency, and (2) producing circular motion. Watts' steam engines were suitable for use in factories and for a variety of purposes.

Important later developments include the steam locomotive and the steam-powered ship.

some time in the 18th century. im pretty sure 1712 was the first engine made
The first practical steam engine was Thomas newcomens machine

The idea of using boiling water to produce mechanical motion has a long history, going back about 2000 years. (see the related link below).

However, the first practical steam-powered 'engine' was a water pump, developed in 1698 by Thomas Savery. Then improving on the design of the 1712 Newcomen engine, the Watt steam engine was developed sporadically from 1763 to 1775 and was the next great step in the development of the steam engine. Then in around 1800, Richard Trevithick introduced engines using high-pressure steam.
the first steam engine was built in the 1700s by Newcomen to drive mine pumps, in England. James Watt greatly improved the engine, early in the Industrial Revolution in Britain(1800s), Steam locomotives have been used to great use by British railways until 1968. Some used by London transport were used until 1971! Yet still steam lives on around the world. In Britain steam locos are used on preserved railways by enthusiasts.

The A1 steam locomotive trust built a whole new steam engine from scratch and was complete in 2008; it is called 'Tornado'.

What is 3.2litre engine?

An engine is measured by the volume of air inside the piston bores. If you've seen an oil commercial and you see those round things hammering up and down, that's a piston. It sits in a sleeve and when it gets to the top, the plug fires, and drives it down again. That's where your drive power comes from. So if you have a 3.2 liter engine, the total amount of air that can be displaced in all the cylinders totals 3.2 liters. If you want to know how much each cylinder can displace you need to divide the volume (3.2 liters) by the number of cylinders you have, and I'd say a 3.2 is almost certainly a 6 cylinder jobbie. So 3.2 liters is equal to 3200 cubic centimeters divided by 6 is about 530 cubic centimeters or, to come back American again, each cylinder has a volume of about half a quart, mas o minos. Phil

Why steam turbine neends gear box?

Steam turbin memerlukan gear box sebagai penyalur tenaga putaran yang dihasilkan oleh turbin. Gear box itu harus berfungsi sebagai reducer gear yang melakukan reduksi terhadap putaran turbin sesuai dengan kebutuhan putaran yang dihasilkan. Misal dari high to low atau low to high. Dalam hal ini kebutuhan dan kapasitas serta aspek-aspek yang lain juga harus diperhitungkan jangan sampai terjadi over load yang akan mengakibatkan kerusakan fatal atau kekurangan tenaga untuk melakukan putaran sehingga tidak maksimal yang berakibat pada pemborosan energi. Steam turbin memiliki putaran yang sangat tinggi dan membutuhkan coupling sebagai penghubung dengan gear box. Menurut saya yang terbaik adalah fluid coupling, dimana pada saat awal steam turbin berputar, tidak akan melakukan hentakan atau sentakan secara mendadak terhadap shaft gear yang dapat mengakibatkan kerusakan pada shaft gear seperti melintir, patah/putus. Tetapi percepatannya bertambah secara bertahap sehingga memiliki kecepatan yang sama dengan steam turbin.

Why alternator space heater used?

Alternators windings do not carry any current when it is not in motion. In high humid environment, the moisture ingress in the windings can reduce the resistance between the winding conductor and the body. When a moist alternator is started, the alternator windings may burn due to short circuit with body. To avoid this, the winding can always be kept warm by using heaters called "space heaters".

Who invented the steam engine?

The first person to harness the power of steam was the Greek scientist Heron of Alexandria in the first century A.D. He developed several devices that were operated by water, steam, or compressed air, including a fountain, a fire engine, and the steam engine.

The "steam engines" in use in the 18th century were not strictly steam engines - the weight of a large rocking beam or pump rod pulled a close-fitting piston along a cylinder, drawing in steam from a boiler. The operator closed a valve to shut off the steam, and opened a valve or tap to let cold water into the cylinder, condensing the steam and creating a partial vacuum. The pressure of the outside air then pushed the piston back into the cylinder. This type of engine is known as an atmospheric or condensing engine - the steam played no direct part in transmitting power to the beam or pump rod.

This type of engine was significantly improved in 1712 by Englishman Thomas Newcomen (1663-1729), who built a machine that was used to pump water out of tin mines in Cornwall.

The Scottish inventor James Watt (1736-1819) realised that most of the heat used to make the steam was being wasted in heating and re-heating the iron cylinder and piston.

He invented a separate condenser, which was a sealed container connected to the cylinder by a pipe. After the piston had drawn steam into the cylinder, water was sprayed into the condenser rather than the cylinder, so the engine worked as before, but the cylinder and piston remained hot. He patented this and several other improvements, and patented (received exclusive rights to make, use, and sell) his own engine in 1769. The engine was very successful because it used as little as a quarter of the wood or expensive coal to produce the same amount of work as Newcomen's engine. He is usually considered to be the father of the steam engine, although he thought the use of high-pressure steam (as used in later engines) to be dangerous, as in fact it tended to be, with the relatively crude cast-iron engineering of the time.

The inventor of what we consider today to be a "steam engine", that is an engine where the pressure of the steam pushes the piston and does the work, was the mining engineer Richard Trevithick (1771 - 1833). A major advantage of his high-pressure engine was that it operated at a much higher speed than the older condensing engine. This made steam-powered vehicles a reality, and he went on to build a steam-powered carriage, and later in 1804 his steam locomotive became the first in the world to pull a heavy load - over a distance of almost 10 miles.

There have been many contributors to the invention of the steam engine and making the steam engine important during the industrial revolution.

Heat balance diagram?

Heat Balance Diagram is representation of Second Law of thermodynamics. in fact it represents the whole cycle of heat inputs and outputs from a steam cycle (generally) especially in case of Thermal Power Stations. Specifications of different components can be identified through Heat Balance Diagram(HBD) thus it helps a lot and indispensable tool while Engineering the Thermal Power Station (TPS)

In fact some commercial software are also available for Heat Balance Diagram. "Simple Heat Balance", "Thermoflow", FCycle are few to name. A comparatively new in this list is Simple Heat Balance, which provides quite accurate results and my team reported me its very intuitive and easy to work with.

Is the expansion of superheated steam isothermal?

Expansion of steam in either the saturated or superheated state is generally not isothermal. When steam expands from a high pressure to a lower pressure the temperature will be reduced, unless energy is added during the process. When steam expands in an engine such as a steam turbine, the temperature reduction is greater than during free expansion

What does steam do to a turbine?

Steam (under pressure) comes into contact with the blades of the turbine through which it is flowing and, by the direct application of force, causes the blades to move, turning the turbine shaft. The turbine coverts the thermal energy of the steam into (rotating) mechanical energy. Surf on over to our friends at Wikipedia using the provided link and get more info. Oh, and check out the pics! Answer it depends what type of turbine one is using

types of steam turbine

1 impulse turbine 2 reaction turbine in 1 st one steam is completely expanded inside nozzle and all pressure energy get converted in to kinetic energy using this impulse force turbine runs.

in 2nd steam is multiple stage blades are used where high pressure superheated steam gets expanded inside the turbine in each stage and after each stage velocity of steam increases.

very high temperature superheated steam is reaquired because it has very high specific volume which helps in reducing mass flow rate of steam.
