Donkey Boiler
There have been a vast number of designs of steam boiler, particularly towards the end of the 19th century when the technology was evolving rapidly. A great many of these took the names of their originators or primary manufacturers, rather than a more descriptive name. Some large manufacturers also made boilers of several types. Accordingly, it is difficult to identify their technical aspects from merely their name. This list presents these known, notable names and a brief description of their main characteristics.

Steam Boiler
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. Type ...

Hungarian State Railways
Hungarian State Railways ( hu, Magyar Államvasutak, MÁV) is the Hungarian national railway company, with divisions "MÁV START Zrt." (passenger transport), "MÁV-Gépészet Zrt." (maintenance), "MÁV-Trakció Zrt." and "MÁV Cargo Zrt" (freight transport). The head office is in Budapest. History 1846–1918 Construction of Hungary's first railway line began in the second half of 1844. The first steam locomotive railway line was opened on 15 July 1846 between Pest and Vác. This date is regarded as the birth date of the Hungarian railways. The Romantic poet Sándor Petőfi rode on the first train and wrote a poem predicting that rails would connect Hungary like blood vessels in the human body. After the failed revolution, the existing lines were nationalized by the Austrian State and new lines were built. As a result of the Austro-Sardinian War in the late 1850s, all these lines were sold to Austrian private companies. During this time the company of Ábrahám Gan ...

Brotan 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] |

Bolsover Express Boiler
Spiral water-tube boilers are a family of vertical water-tube boilers. Their steam generating tubes are narrow spiral tubes, arranged in circular fashion around a central vertical water drum. The water tubes are long, numerous and of diameter, or smaller. This gives an extremely large heating area, and so good steam raising capabilities. "A maximum fire surface is obtained in a given space, and great economies in fuel are thereby made possible." As both drum and tubes are of small diameter, the boilers are also suitable for high pressure use. However the boilers entered service early on, as one of the first small-tube water-tube designs and so they have rarely been used for high pressures or with steam turbines. Differences between these types of boiler are in the arrangement of their water tubes. They all share the same basic layout. The outer casing of the boiler is of steel plates, lined with firebrick, and plays no part in their heating area. Climax boiler The large in ...

Vertical Boiler With Horizontal Fire-tubes
A vertical boiler with horizontal fire-tubes is a type of small vertical boiler, used to generate steam for small machinery. It is characterised by having many narrow fire-tubes, running horizontally. Boilers like this have been widely used on ships as either ''auxiliary'' or ''donkey'' boilers. Smaller examples, particularly the Robertson type have been used for steam wagons. Parallel tube boilers Parallel tube boilers place all of their fire-tubes in a single parallel group, running from side to side of the boiler shell. The best known of these is the Cochran design. Cochran boiler The Cochran boiler was produced by Cochran & Co. of Annan, Scotland. It is widely used in marine practice, either fired directly by coal or oil fuels, or else used for heat recovery from the exhaust of large diesel engines. Where such a boiler may be heated either by the exhaust gases of the main propulsion plant, or else separately fired when in port (usually by oil rather than coal) it is ...

Steam Generator (boiler)
A steam generator is a form of low water-content boiler, similar to a flash steam boiler. The usual construction is as a spiral coil of water-tube, arranged as a single, or monotube, coil. Circulation is once-through and pumped under pressure, as a forced-circulation boiler. The narrow-tube construction, without any large-diameter drums or tanks, means that they are safe from the effects of explosion,This safety from explosion is due to two causes. Firstly, small diameter tubes are inherently stronger than large tubes of the same construction, as was first appreciated by William Fairbairn in the mid-19th century. Secondly, the low water-content means that there is relatively little volume of water per area of heating surface (i.e. boiler power). As the destructive energy of a boiler explosion is largely due to the sudden release of this energy, and proportional to water volume, a low water-content boiler has a more favourable ratio of useful power (from its area) to risk (from ...

Monotube Boiler
A monotube steam generator is a type of steam generator consisting of a single tube, usually in a multi-layer spiral, that forms a once-through steam generator (OTSG). The first of these was the Herreshoff steam generator of 1873. Principles For the sake of efficiency, it is desirable to minimise the steam content of the generator. Heat can then be transferred efficiently into liquid water, rather than into low-density steam. Monotube steam generators may either boil gradually along their length, usually pumped circulation systems, but where this boiling does not disrupt the circulation. Otherwise they can use the Benson supercritical system, where the pressure is sufficient to prevent boiling (within the heated volume) altogether. Examples Examples of Monotube steam generators include: * Industrial steam generators * The water-tube boilers of the monotube type used in steam cars, such as: ** AMC ** Clayton Steam Generator ** Doble ** Gardner-Serpollet ** Locomobile Company o ...

Benson Boiler
A supercritical steam generator is a type of boiler that operates at supercritical pressure, frequently used in the production of electric power. In contrast to a subcritical boiler in which bubbles can form, a supercritical steam generator operates at pressures above the critical pressure. Therefore, liquid water immediately becomes indistinguishable from steam. Water passes below the critical point as it does work in a high pressure turbine and enters the generator's condenser, resulting in slightly less fuel use. The efficiency of power plants with supercritical steam generators is higher than with subcritical steam. Only with high pressure can higher temperature steam be converted more efficiently to mechanical energy in the turbine (as given by Carnot's theorem). Technically, the term "boiler" should not be used for a supercritical pressure steam generator as no "boiling" actually occurs in the device.
