NER Class S2
The North Eastern Railway Class S2 - London and North Eastern Railway Class B15 - was a mixed-traffic 4-6-0 steam locomotive designed by Vincent Raven. The design was based on NER Class S. Superheaters The first seven was built with saturated (non-superheated) boilers, however the remaining thirteen were fitted with Robinson 24-element superheaters. The saturated B15s were eventually fitted with superheaters. Some of these rebuilds used Schmidt superheaters, however they were eventually converted to use Robinson superheaters, as Robinson superheaters were the LNER’s standard type of superheaters. No.825 The last of the class, No.825 was fitted with Stumpf Uniflow cylinders. The inlet and exhaust ports were separate. Although the exhaust port was always the same size, the inlet port could vary in size according to the position of the cutoff. In 1918, the system was used on C7 No.2212, with a tidier result. Due to the special attention required for these experimental locom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vincent Raven
Sir Vincent Litchfield Raven, KBE (3 December 1859 – 14 February 1934) was an English railway engineer, and was chief mechanical engineer of the North Eastern Railway from 1910 to 1922. Biography Vincent Raven was born the son of a clergyman at Great Fransham rectory in Norfolk and educated at Aldenham School in Hertfordshire. In 1877 he began his career with the North Eastern Railway as a pupil of the then Locomotive Superintendent, Edward Fletcher. By 1893 he had achieved the post of Assistant Mechanical Engineer to Wilson Worsdell who was then the Locomotive Superintendent. In this post he was involved for the first time with an electrification project, as the N.E.R. was electrifying the North Tyneside suburban route in 1904. This was a third rail system at 600 volts DC. Steam locomotives In 1910 he became Chief Mechanical Engineer on Wilson Worsdell's retirement (The title of the post had changed from Locomotive Superintendent in 1902). Raven developed some of Worsd ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Uniflow Steam Engine
The uniflow type of steam engine uses steam that flows in one direction only in each half of the cylinder. Thermal efficiency is increased by having a temperature gradient along the cylinder. Steam always enters at the hot ends of the cylinder and exhausts through ports at the cooler centre. By this means, the relative heating and cooling of the cylinder walls is reduced. Design details Steam entry is usually controlled by poppet valves (which act similarly to those used in internal combustion engines) that are operated by a camshaft. The inlet valves open to admit steam when minimum expansion volume has been reached at the start of the stroke. For a period of the crank cycle, steam is admitted, and the poppet inlet is then closed, allowing continued expansion of the steam during the stroke, driving the piston. Near the end of the stroke, the piston will uncover a ring of exhaust ports mounted radially around the centre of the cylinder. These ports are connected by a manifold an ...

Scrapped Locomotives
Scrap consists of recyclable materials, usually metals, left over from product manufacturing and consumption, such as parts of vehicles, building supplies, and surplus materials. Unlike waste, scrap has monetary value, especially recovered metals, and non-metallic materials are also recovered for recycling. Once collected, the materials are sorted into types — typically metal scrap will be crushed, shredded, and sorted using mechanical processes. Scrap recycling is important for creating a more sustainable economy or creating a circular economy, using significantly less energy and having far less environmental impact than producing metal from ore. Metal recycling, especially of structural steel, ships, used manufactured goods, such as vehicles and white goods, is a major industrial activity with complex networks of wrecking yards, sorting facilities and recycling plants. Processing Scrap metal originates both in business and residential environments. Typically a "scrapper" ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
North Eastern Railway Locomotives
North is one of the four compass points or cardinal directions. It is the opposite of south and is perpendicular to east and west. ''North'' is a noun, adjective, or adverb indicating direction or geography. Etymology The word ''north'' is related to the Old High German ''nord'', both descending from the Proto-Indo-European unit *''ner-'', meaning "left; below" as north is to left when facing the rising sun. Similarly, the other cardinal directions are also related to the sun's position. The Latin word ''borealis'' comes from the Greek '' boreas'' "north wind, north", which, according to Ovid, was personified as the wind-god Boreas, the father of Calais and Zetes. ''Septentrionalis'' is from ''septentriones'', "the seven plow oxen", a name of ''Ursa Major''. The Greek ἀρκτικός (''arktikós'') is named for the same constellation, and is the source of the English word ''Arctic''. Other languages have other derivations. For example, in Lezgian, ''kefer'' can mean b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Skelton, York
Skelton is a village and civil parish in the unitary authority of the City of York, in North Yorkshire, England. It is north-north-west of the city of York, west of Haxby, and on the east bank of the River Ouse. Skelton was in the ancient royal Forest of Galtres and covers . Skelton was made a conservation area in 1973. The village name probably began as the Anglo-Saxon 'Shelfton'—'the settlement on high ground'—becoming the present 'Skelton' under the invading Danes. The village, along with nearby Overton, is mentioned in the Domesday Book. According to the 2001 census the parish had a population of 1,640, reducing to 1,549 at the 2011 census. The village was historically part of the North Riding of Yorkshire until 1974. It was then a part of the district of Ryedale in North Yorkshire from 1974 until 1996. Since 1996 it has been part of the City of York unitary authority. History Skelton is mentioned in the Domesday Book, but its name indicates Anglo-Saxon and Danish i ...

LNER Class B13
The North Eastern Railway Class S (LNER Class B13) was a 4-6-0 type of steam locomotive designed for express passenger workings. The first example was built in 1899. They were very similar to the NER Class S1, except for the smaller wheels of the former. Design They were designed to reduce double heading on the East Coast Main Line. However they steamed poorly, with a smaller and shallower grate than was used even by other locomotives at the time, and the 4-4-0s of the NER Class R quickly replaced them, with the 4-4-2 layout being preferred for later express passenger designs. The class were re-classified as London and North Eastern Railway Class B13 in 1923. Modifications The first seven locomotives had slide valves, while the remainder had piston valves Piston valves are one form of valve used to control the flow of steam within a steam engine or locomotive. They control the admission of steam into the cylinders and its subsequent exhausting, enabling a locom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NER Class Z
The NER class Z (LNER Class C7) was an Atlantic class of locomotives designed by Vincent Raven. It was introduced in 1911. Construction Originally classified NER Class V2, the first 20 were built in 1911. Ten were saturated and the others were superheated. The saturated locos were superheated between 1914 and 1915, while all subsequent locomotives were superheated. 50 class Zs were built between 1911 and 1918, in 5 batches. Originally the locomotives were built with Schmidt superheaters, however from 1931 onwards 27 C7s were fitted with Robinson superheaters. Variations No.2212 The last of the 50 locos, No.2212 was built with Stumpf Uniflow cylinders. This arrangement had been used on LNER Class B15 No.825 with an untidy result, however the arrangement had been tidied up for No.2212. Double-length cylinders were required, thus a longer front bogie and smaller wheels were fitted. This arrangement, although requiring special attention (as with No.825) was used until 1934, when ...

Wilhelm Schmidt (engineer)
Wilhelm Schmidt, known as Hot Steam Schmidt (German: ''Heißdampf-Schmidt'') (1858–1924) was a German engineer and inventor who achieved the breakthrough in the development of superheated steam technology for steam engines. Wilhelm Schmidt was born in Wegeleben in the Prussian Province of Saxony on 18 February 1858. Education At school Wilhelm Schmidt had difficulties with reading, writing and arithmetic, a case of dyslexia. For example, he was unable to recite the alphabet without hesitation all his life. Nor could he memorise poetry or prose. He developed a passion for drawing, however, and for machines. Career Schmidt began his professional career as a machine fitter. He studied at the technical high school in Dresden under Gustav Zeuner. Superheated steam In 1883 he took a post as a civil engineer in Kassel, where he developed superheated steam technology to the point where it could be practically used. In 1908 he transferred his home and the base of his firm to Be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
4-6-0
A 4-6-0 steam locomotive, under the Whyte notation for the classification of steam locomotives by wheel arrangement, has four leading wheels on two axles in a leading bogie and six powered and coupled driving wheels on three axles with the absence of trailing wheels. In the mid-19th century, this wheel arrangement became the second-most-popular configuration for new steam locomotives in the United States, where this type is commonly referred to as a ten-wheeler.White, John H., Jr. (1968). ''A history of the American locomotive; its development: 1830-1880''. New York, NY: Dover Publications. p. 57. As locomotives pulling trains of lightweight all-wood passenger cars from the 1890 to the 1920s, they were exceptionally stable at near speeds on the New York Central's New York-to-Chicago Water Level Route and on the Reading Railroad's line from Camden to Atlantic City, New Jersey.

Superheater
A superheater is a device used to convert saturated steam or wet steam into superheated steam or dry steam. Superheated steam is used in steam turbines for electricity generation, steam engines, and in processes such as steam reforming. There are three types of superheaters: radiant, convection, and separately fired. A superheater can vary in size from a few tens of feet to several hundred feet (a few metres to some hundred metres). Types * A radiant superheater is placed directly in radiant zone of the combustion chamber near the water wall so as to absorb heat by radiation. * A convection superheater is located in the convective zone of the furnace usually ahead of economizer (in the path of the hot flue gases). These are also called primary superheaters. * A separately fired superheater is a superheater that is placed outside the main boiler, which has its own separate combustion system. This superheater design incorporates additional burners in the area of superheater pipes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
