Stationary Engines
A stationary engine is an engine whose framework does not move. They are used to drive immobile equipment, such as pumps, electric generator, generators, mill (grinding), mills or factory machinery, or cable car (railway), cable cars. The term usually refers to large immobile reciprocating engines, principally stationary steam engines and, to some extent, stationary internal combustion engines. Other large immobile power sources, such as steam turbines, gas turbines, and large electric motors, are categorized separately. Stationary engines, especially stationary steam engines were once widespread in the late Industrial Revolution. This was an era when each factory or mill generated its own power, and power transmission was mechanical (via line shafts, belt (mechanical), belts, gear trains, and clutches). Applications for stationary engines have declined since electrification has become widespread; most industrial uses today draw electricity from an electrical grid and distribute ...

Three Heavy-oil Stationary Engines
3 (three) is a number, numeral (linguistics), numeral and numerical digit, digit. It is the natural number following 2 and preceding 4, and is the smallest odd prime number and the only prime preceding a square number. It has religious and cultural significance in many societies. Evolution of the Arabic digit The use of three lines to denote the number 3 occurred in many writing systems, including some (like Roman and Chinese numerals) that are still in use. That was also the original representation of 3 in the Brahmic numerals, Brahmic (Indian) numerical notation, its earliest forms aligned vertically. However, during the Gupta Empire the sign was modified by the addition of a curve on each line. The Nāgarī script rotated the lines clockwise, so they appeared horizontally, and ended each line with a short downward stroke on the right. In cursive script, the three strokes were eventually connected to form a glyph resembling a with an additional stroke at the bottom: ३. ...

Electrification
Electrification is the process of powering by electricity and, in many contexts, the introduction of such power by changing over from an earlier power source. In the context of history of technology and economic development, electrification refers to the build-out of the electricity generation and electric power distribution systems. In the context of sustainable energy, electrification refers to the build-out of super grids and smart grids with distributed energy resources (such as energy storage) to accommodate the energy transition to renewable energy and the switch of end-uses to electricity. The electrification of particular sectors of the economy, particularly out of context, is called by modified terms such as Mass production#Factory electrification, ''factory electrification'', ''household electrification'', ''rural electrification'' and ''railway electrification''. In the context of sustainable energy, terms such as ''transport electrification'' (referring to electric v ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gasoline
Gasoline ( North American English) or petrol ( Commonwealth English) is a petrochemical product characterized as a transparent, yellowish, and flammable liquid normally used as a fuel for spark-ignited internal combustion engines. When formulated as a fuel for engines, gasoline is chemically composed of organic compounds derived from the fractional distillation of petroleum and later chemically enhanced with gasoline additives. It is a high-volume profitable product produced in crude oil refineries. The ability of a particular gasoline blend to resist premature ignition (which causes knocking and reduces efficiency in reciprocating engines) is measured by its octane rating. Tetraethyl lead was once widely used to increase the octane rating but is not used in modern automotive gasoline due to the health hazard. Aviation, off-road motor vehicles, and racing car engines still use leaded gasolines. Other substances are frequently added to gasoline to improve chemical st ...

Steam Engine
A steam engine is a heat engine that performs Work (physics), mechanical work using steam as its working fluid. The steam engine uses the force produced by steam pressure to push a piston back and forth inside a Cylinder (locomotive), cylinder. This pushing force can be transformed by a connecting rod and Crank (mechanism), crank into rotational force for work. The term "steam engine" is most commonly applied to reciprocating engines as just described, although some authorities have also referred to the steam turbine and devices such as Hero's aeolipile as "steam engines". The essential feature of steam engines is that they are external combustion engines, where the working fluid is separated from the combustion products. The ideal thermodynamic cycle used to analyze this process is called the Rankine cycle. In general usage, the term ''steam engine'' can refer to either complete steam plants (including Boiler (power generation), boilers etc.), such as railway steam locomot ...

Power Station
A power station, also referred to as a power plant and sometimes generating station or generating plant, is an industrial facility for the electricity generation, generation of electric power. Power stations are generally connected to an electrical grid. Many power stations contain one or more Electric generator, generators, rotating machine that converts mechanical power into three-phase electric power. The relative motion between a magnetic field and a Electrical conductor, conductor creates an electric current. The energy source harnessed to turn the generator varies widely. Most power stations in the world burn fossil fuels such as coal, petroleum, oil, and natural gas to generate electricity. Low-carbon power sources include nuclear power, and use of renewable energy, renewables such as solar power, solar, wind power, wind, geothermal power, geothermal, and hydroelectricity, hydroelectric. History In early 1871 Belgian inventor Zénobe Gramme invented a generator powerfu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Small-scale Electricity Generation
Microgeneration is the small-scale production of heat or electric power from a "low carbon source," as an alternative or supplement to traditional centralized grid-connected power. Microgeneration technologies include small-scale wind turbines, micro hydro, solar PV systems, microbial fuel cells, ground source heat pumps, and micro combined heat and power installations. These technologies are often combined to form a hybrid power solution that can offer superior performance and lower cost than a system based on one generator. History In the United States, Microgeneration had its roots in the 1973 oil crisis and the Yom Kippur War which prompted innovation. On June 20, 1979, 32 solar panels were installed at the White House. The solar cells were dismantled 7 years later during the Reagan administration. The use of Solar water heating dates back before 1900 with "the first practical solar cell being developed by Bell Labs in 1954." The "University of Delaware is credited wi ...

Mains Electricity
Mains electricity, utility power, grid power, domestic power, wall power, household current, or, in some parts of Canada, hydro, is a general-purpose Alternating current, alternating-current (AC) electric power supply. It is the form of electrical power that is delivered to homes and businesses through the electrical grid in many parts of the world. People use this electricity to power everyday items (such as domestic appliances, televisions and lamps) by plugging them into a wall outlet. The voltage and utility frequency, frequency of electric power differs between regions. In much of the world, a voltage (nominally) of 230 volts and frequency of 50 Hz is used. In North America, the most common combination is 120 V and a frequency of 60 Hz. Other combinations exist, for example, 230 V at 60 Hz. Travellers' portable appliances may be inoperative or damaged by foreign electrical supplies. Non-interchangeable AC power plugs and sockets, plugs and sock ...

Hot Tube Engine
The hot tube engine is a primitive and long-obsolete type of combustion engine. Invented before reliable magnetos could be made, they use a separated heat source to ignite their combustion chambers, called a hot-tube ignitor. The hot-tube ignitor has the same function as a spark plug does in a modern, spark-ignited engine. The timing of a hot tube engine is controlled by means of varying the length of the hot-tube ignitor. Length of the tube controls when the charge ignites, and the ignition timing can be optimized so as to allow different operating speeds to be selected, much like a spark advance control. It was mostly used as a stationary engine on farms but was also found in very early automobiles and motorcycles. Contrary to the aforementioned hot-bulb engine The hot-bulb engine, also known as a semi-diesel or Akroyd engine, is a type of internal combustion engine in which fuel ignites by coming in contact with a red-hot metal surface inside a bulb, followed by the int ...

Hot Bulb Engine
The hot-bulb engine, also known as a semi-diesel or Akroyd engine, is a type of internal combustion engine in which fuel Combustion, ignites by coming in contact with a red-hot metal surface inside a bulb, followed by the introduction of air (oxygen) compressed into the hot-bulb chamber by the rising piston. There is some ignition when the fuel is introduced, but it quickly uses up the available oxygen in the bulb. Vigorous ignition takes place only when sufficient oxygen is supplied to the hot-bulb chamber on the compression stroke of the engine. Most hot-bulb engines were produced as one or two-cylinder, low-speed two-stroke engine, two-stroke crankcase scavenging (automotive), scavenged units. History Four-stroke Hornsby–Akroyd oil engine The concept of this engine was established by Herbert Akroyd Stuart, an English inventor. The first prototypes were built in 1886 and production started in 1891 by Richard Hornsby & Sons of Grantham, Lincolnshire, England under the t ...

Hit And Miss Engine
A hit-and-miss engine or Hit 'N' Miss is a type of Stationary engine, stationary internal combustion engine that is controlled by a Governor (device), governor to only fire at a set speed. They are usually 4-stroke, but 2-stroke versions were also made. It was conceived in the late 19th century and produced by various companies from the 1890s through approximately the 1940s. The name comes from the speed control on these engines: they fire ("hit") only when operating at or below a set speed, and cycle without firing ("miss") when they exceed their set speed. This is as compared to the "throttle-governed" method of speed control. The sound made when the engine is running without a load is a distinctive "Snort POP whoosh whoosh whoosh whoosh snort POP" as the engine fires and then coasts until the speed decreases and it fires again to maintain its average speed. The snorting is caused by the atmospheric intake valve used on many of these engines. Many engine manufacturers made hit-a ...

Stationary Steam Engine
Stationary steam engines are fixed steam engines used for pumping or driving mills and factories, and for power generation. They are distinct from locomotive engines used on railways, traction engines for heavy steam haulage on roads, steam cars (and other motor vehicles), agricultural engines used for ploughing or threshing, marine engines, and the steam turbines used as the mechanism of power generation for most nuclear power plants. They were introduced during the 18th century and widely made for the whole of the 19th century and most of the first half of the 20th century, only declining as electricity supply and the internal combustion engine became more widespread. Types of stationary steam engine There are different patterns of stationary steam engines, distinguished by the layout of the cylinders and crankshaft: * Beam engines have a rocking beam providing the connection between the vertical cylinder and crankshaft. * Table engines have the crosshead above the v ...
