Ceinture 81 To 93
Ceinture 81 to 93 were a class of thirteen 4-6-4T ("''Baltic''") tank locomotives designed by Gaston du Bousquet of the Chemins de fer du Nord for the ''Syndicat d'Exploitation des Chemins de fer de Ceinture de Paris''. They were almost identical to the 3.801 to 3.865, series that the Nord had built for itself in its own workshops at ( fr) and Hellemmes. The Ceinture locomotives were built in 1909 by Société française de constructions mécaniques. Six locomotives were fitted with superheaters between 1924 and 1928; Number 85 has a 21-element superheater, the remaining five, 81, 82, 84, 86, and 93, has 24-element superheaters. In addition 85 received Caprotti rotary-cam valve gear. Eleven locomotives received feedwater heaters: eight, 81 and 85 to 91, were by ACFI; three 83, 84 and 93 were by Caille Potonie. In 1934 at the dissolution of the ''Syndicat'' they passed to the Chemins de fer de l'État, who did not renumber them. At nationalisation in 1938, they all pas ...

Gaston Du Bousquet
Gaston du Bousquet (1839–1910) was a French engineer who was Chief of Motive Power () of the Chemin de Fer du Nord, designer of locomotives and professor at École centrale de Lille. Steam locomotive designer Gaston du Bousquet taught mechanical engineering at the Institut industriel du Nord de la France (École Centrale de Lille) from 1872. He was appointed chief engineer to the Chemins de Fer du Nord in 1890. He won a gold medal at the Universal Exhibition of 1894. He collaborated successfully with Alfred de Glehn and Edward Beugniot, both working for the Société Alsacienne de Constructions Mécaniques (SACM). He was president of the Society of Civil Engineers of France in 1894.

Caprotti Valve Gear
The Caprotti valve gear is a type of steam engine valve gear invented in the early 1920s by Italian architect and engineer Arturo Caprotti. It uses camshafts and poppet valves rather than the piston valves used in other valve gear. While basing his design on automotive valves, Caprotti made several significant departures from this design to adapt the valves for steam. Having agreed a joint-venture with Worcester-based engineering company Heenan & Froude from 1938, Heenan & Froude fully acquired Caprotti post-World War II in 1947. Usage in Italy The Caprotti valve gear was first tested on a Ferrovie dello Stato Italiane Class 740 2-8-0 mixed-traffic locomotive in 1921; although more expensive and complicated than the standard piston valves, it substantially improved the locomotive's performance. Until the 1930s it was fitted on some 334 FS locomotives and on 77 narrow-gauge locomotives of other companies; of the former, some were new-builds, the others were rebuilds of non-su ...

Railway Locomotives Introduced In 1909
Rail transport (also known as train transport) is a means of transport that transfers passengers and goods on wheeled vehicles running on rails, which are incorporated in tracks. In contrast to road transport, where the vehicles run on a prepared flat surface, rail vehicles (rolling stock) are directionally guided by the tracks on which they run. Tracks usually consist of steel rails, installed on sleepers (ties) set in ballast, on which the rolling stock, usually fitted with metal wheels, moves. Other variations are also possible, such as "slab track", in which the rails are fastened to a concrete foundation resting on a prepared subsurface. Rolling stock in a rail transport system generally encounters lower frictional resistance than rubber-tyred road vehicles, so passenger and freight cars (carriages and wagons) can be coupled into longer trains. The operation is carried out by a railway company, providing transport between train stations or freight customer facil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
4-6-4T Locomotives
Under the Whyte notation for the classification of locomotives, represents the wheel arrangement of four leading wheels, six powered and coupled driving wheels and four trailing wheels. In France where the type was first used, it is known as the Baltic while it became known as the Hudson in most of North America. Overview Tender locomotives The 4-6-4 tender (rail), tender locomotive was first introduced in 1911 and throughout the 1920s to 1940s, the wheel arrangement was widely used in North America and to a lesser extent in the rest of the world. The type combined the basic design principles of the 4-6-2 type with an improved boiler and larger Firebox (steam engine), firebox that necessitated additional support at the rear of the locomotive. In general, the available tractive effort differed little from that of the 4-6-2, but the steam-raising ability was increased, giving more power at speed. The 4-6-4 was best suited to high-speed running across flat terrain. Since the type h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steam Locomotives Of France
Steam is a substance containing water in the gas phase, and sometimes also an aerosol of liquid water droplets, or air. This may occur due to evaporation or due to boiling, where heat is applied until water reaches the enthalpy of vaporization. Steam that is saturated or superheated is invisible; however, "steam" often refers to wet steam, the visible mist or aerosol of water droplets formed as water vapor condenses. Water increases in volume by 1,700 times at standard temperature and pressure; this change in volume can be converted into mechanical work by steam engines such as reciprocating piston type engines and steam turbines, which are a sub-group of steam engines. Piston type steam engines played a central role in the Industrial Revolution and modern steam turbines are used to generate more than 80% of the world's electricity. If liquid water comes in contact with a very hot surface or depressurizes quickly below its vapor pressure, it can create a steam explosion. Types ...

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Feedwater Heater
A feedwater heater is a power plant component used to pre-heat water delivered to a steam generating boiler. Preheating the feedwater reduces the irreversibilities involved in steam generation and therefore improves the thermodynamic efficiency of the system.Fundamentals of Steam Power by Kenneth Weston, University of Tulsa This reduces plant operating costs and also helps to avoid thermal shock to the boiler metal when the feedwater is introduced back into the steam cycle. In a steam power plant (usually modeled as a modified Rankine cycle), feedwater heaters allow the feedwater to be brought up to the saturation temperature very gradually. This minimizes the inevitable irreversibilities associated with heat transfer to the working fluid (water). See the article on the second law of thermodynamics for a fur ...

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] |
