Schmidt High-pressure System
A high-pressure steam locomotive is a steam locomotive with a boiler that operates at pressures well above what would be considered normal for other locomotives. In the later years of steam, boiler pressures were typically . High-pressure locomotives can be considered to start at , when special construction techniques become necessary, but some had boilers that operated at over . The reason for high pressure Maximising the efficiency of a heat engine depends fundamentally upon getting the temperature at which heat is accepted (i.e. raising steam in the boiler) as far as possible from the temperature at which it is rejected (i.e. the steam when it leaves the cylinder). This was quantified by Nicolas Léonard Sadi Carnot. There are two options: raise the acceptance temperature or lower the rejection temperature. For a steam engine, the former means raising steam at higher pressure and temperature, which is in engineering terms fairly straightforward. The latter means bigger cylinder ...

Steam Locomotive
A steam locomotive is a locomotive that provides the force to move itself and other vehicles by means of the expansion of steam. It is fuelled by burning combustible material (usually coal, oil or, rarely, wood) to heat water in the locomotive's boiler to the point where it becomes gaseous and its volume increases 1,700 times. Functionally, it is a steam engine on wheels. In most locomotives, the steam is admitted alternately to each end of its cylinders, in which pistons are mechanically connected to the locomotive's main wheels. Fuel and water supplies are usually carried with the locomotive, either on the locomotive itself or in a tender coupled to it. Variations in this general design include electrically-powered boilers, turbines in place of pistons, and using steam generated externally. Steam locomotives were first developed in the United Kingdom during the early 19th century and used for railway transport until the middle of the 20th century. Richard Trevithick ...

London And South Western Railway
The London and South Western Railway (LSWR, sometimes written L&SWR) was a railway company in England from 1838 to 1922. Originating as the London and Southampton Railway, its network extended to Dorchester and Weymouth, to Salisbury, Exeter and Plymouth, and to Padstow, Ilfracombe and Bude. It developed a network of routes in Hampshire, Surrey and Berkshire, including Portsmouth and Reading. The LSWR became famous for its express passenger trains to Bournemouth and Weymouth, and to Devon and Cornwall. Nearer London it developed a dense suburban network and was pioneering in the introduction of a widespread suburban electrified passenger network. It was the prime mover of the development of Southampton Docks, which became an important ocean terminal as well as a harbour for cross channel services and for Isle of Wight ferries. Although the LSWR's area of influence was not the home of large-scale heavy industry, the transport goods and mineral traffic was a major activity, a ...

Baldwin 60000
Baldwin 60000 is an experimental steam locomotive built by the Baldwin Locomotive Works in Eddystone, Pennsylvania, in 1926, during the height of the railroading industry. It received its number for being the 60,000th locomotive built by Baldwin. It was designed to be the best locomotive that Baldwin ever made. It boasts three cylinders, weighs about , including tender, and can pull a load of up to . Its top speed is . 60000 was very innovative, carrying unusual technology, including a water-tube firebox. This was intended to improve efficiency but the tubes were prone to burst inside the firebox. It is also a compound, expanding the steam once in the inside cylinder and then again in the two outside cylinders. Although compounding increases efficiency, it was an extra complication that the US railroads had mostly rejected by the middle twenties. The weight and length of the engine were too much for all but the heaviest and straightest tracks. This locomotive was experimental ...

DRG H 02 1001
The DRG H 02 1001 was a remarkable high-pressure steam locomotive, built by the engineering firm of Schwarzkopff to the design of Dr L. Löffler. The aim was not only to improve fuel economy—the usual reason for adopting high steam pressures—but also to increase the amount of power that could be produced within the German loading gauge. The H02 1001 locomotive was the only example of the Schwarzkopff-Löffler high-pressure boiler system, a complex technology in which heat was extracted from the firebox by tubes filled with steam rather than boiling water. It was delivered in 1930 to the Deutsche Reichsbahn (DRG). Schwarzkopff guaranteed in the purchase contract a coal saving of 42% over a standard 01 locomotive design, but in the event the DRG never bought the locomotive. Steam was delivered at no less than to two very small outside cylinders of diameter. These were compounded with a single LP inside cylinder. The wheel arrangement was 4-6-2. After exte ...

Canadian 8000
Canadians (french: Canadiens) are people identified with the country of Canada. This connection may be residential, legal, historical or cultural. For most Canadians, many (or all) of these connections exist and are collectively the source of their being ''Canadian''. Canada is a multilingual and multicultural society home to people of groups of many different ethnic, religious, and national origins, with the majority of the population made up of Old World immigrants and their descendants. Following the initial period of French and then the much larger British colonization, different waves (or peaks) of immigration and settlement of non-indigenous peoples took place over the course of nearly two centuries and continue today. Elements of Indigenous, French, British, and more recent immigrant customs, languages, and religions have combined to form the culture of Canada, and thus a Canadian identity. Canada has also been strongly influenced by its linguistic, geographic, and e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

French PL241P
The PLM 241 B 1 was a high-pressure steam locomotive built in 1929 for the PLM (Chemins de fer de Paris à Lyon et à la Méditerranée) using the Schmidt high-pressure system. It was a 4-cylinder compound design. The manufacturer was Henschel & Sohn of Germany; it was most unusual for a French railway to buy German technology, there being somewhat less than total trust of Germany at the time. Schmidt and Henschel seem to have been the only sources of suitable technology. Only one was built. The locomotive was scrapped in 1936. *Boiler: 3-stage boiler; high pressure circuit: 110 kp/cm² (10.8 MPa, 1,560 psi Psi, PSI or Ψ may refer to: Alphabetic letters * Psi (Greek) (Ψ, ψ), the 23rd letter of the Greek alphabet * Psi (Cyrillic) (Ѱ, ѱ), letter of the early Cyrillic alphabet, adopted from Greek Arts and entertainment * "Psi" as an abbreviation ...)' secondary circuit: 58 kp/cm²; low-pressure circuit: 13 kp/cm² *Power: 2530 hpi (1.89 MW) *Speed (attained) 110 ...

Fire Tube Boiler
A fire-tube boiler is a type of boiler in which hot gases pass from a fire through one or more tubes running through a sealed container of water. The heat of the gases is transferred through the walls of the tubes by thermal conduction, heating the water and ultimately creating steam. The fire-tube boiler developed as the third of the four major historical types of boilers: low-pressure tank or "haystack" boilers, flued boilers with one or two large flues, fire-tube boilers with many small tubes, and high-pressure water-tube boilers. Their advantage over flued boilers with a single large flue is that the many small tubes offer far greater heating surface area for the same overall boiler volume. The general construction is as a tank of water penetrated by tubes that carry the hot flue gases from the fire. The tank is usually cylindrical for the most part—being the strongest practical shape for a pressurized container—and this cylindrical tank may be either horizontal or vert ...

Water Tube Boiler
A high pressure watertube boiler (also spelled water-tube and water tube) is a type of boiler in which water circulates in tubes heated externally by the fire. Fuel is burned inside the furnace, creating hot gas which boils water in the steam-generating tubes. In smaller boilers, additional generating tubes are separate in the furnace, while larger utility boilers rely on the water-filled tubes that make up the walls of the furnace to generate steam. The heated water/steam mixture then rises into the steam drum. Here, saturated steam is drawn off the top of the drum. In some services, the steam passes through tubes in the hot gas path, (a superheater) to become superheated. Superheated steam is defined as steam that is heated above the boiling point at a given pressure. Superheated steam is a dry gas and therefore is typically used to drive turbines, since water droplets can severely damage turbine blades. Saturated water at the bottom of the steam drum returns to the lower drum ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carbon Dioxide
Carbon dioxide (chemical formula ) is a chemical compound made up of molecules that each have one carbon atom covalently double bonded to two oxygen atoms. It is found in the gas state at room temperature. In the air, carbon dioxide is transparent to visible light but absorbs infrared radiation, acting as a greenhouse gas. It is a trace gas in Earth's atmosphere at 421 parts per million (ppm), or about 0.04% by volume (as of May 2022), having risen from pre-industrial levels of 280 ppm. Burning fossil fuels is the primary cause of these increased CO2 concentrations and also the primary cause of climate change.IPCC (2022Summary for policy makersiClimate Change 2022: Mitigation of Climate Change.

Oxygen
Oxygen is the chemical element with the symbol O and atomic number 8. It is a member of the chalcogen group in the periodic table, a highly reactive nonmetal, and an oxidizing agent that readily forms oxides with most elements as well as with other compounds. Oxygen is Earth's most abundant element, and after hydrogen and helium, it is the third-most abundant element in the universe. At standard temperature and pressure, two atoms of the element bind to form dioxygen, a colorless and odorless diatomic gas with the formula . Diatomic oxygen gas currently constitutes 20.95% of the Earth's atmosphere, though this has changed considerably over long periods of time. Oxygen makes up almost half of the Earth's crust in the form of oxides.Atkins, P.; Jones, L.; Laverman, L. (2016).''Chemical Principles'', 7th edition. Freeman. Many major classes of organic molecules in living organisms contain oxygen atoms, such as proteins, nucleic acids, carbohydrates, and fats, as ...
