Blau Gas
Blau gas (german: Blaugas) is an artificial illuminating gas, similar to propane, named after its inventor, Hermann Blau of Augsburg, Germany. Not or rarely used or produced today, it was manufactured by decomposing mineral oils in retorts by heat, and compressing the resulting naphtha until it liquefied. It was transported in liquid condition, and, like LPG, when released returns to a gaseous state. Blau gas has a rather water-like color. It was historically stored in steel cylinders for shipment, and, around the turn of the century, had the advantage of possessing the highest specific energy of all artificially produced gases. Chemically, Blau gas is similar to coal gas, but, unlike coal gas, is free from carbon monoxide. Furthermore, Blau gas is difficult to bring to explosion. Blau gas was burned for lighting and heating; a less-pure form known as Pintsch gas fuelled illuminated buoys and beacons (for navigation), railroad car lights and stoves in the late 19th and ear ...

Airship
An airship or dirigible balloon is a type of aerostat or lighter-than-air aircraft that can navigate through the air under its own power. Aerostats gain their lift from a lifting gas that is less dense than the surrounding air. In early dirigibles, the lifting gas used was hydrogen, due to its high lifting capacity and ready availability. Helium gas has almost the same lifting capacity and is not flammable, unlike hydrogen, but is rare and relatively expensive. Significant amounts were first discovered in the United States and for a while helium was only available for airships in that country. Most airships built since the 1960s have used helium, though some have used hot air.A few airships after World War II used hydrogen. The first British airship to use helium was the ''Chitty Bang Bang'' of 1967. The envelope of an airship may form the gasbag, or it may contain a number of gas-filled cells. An airship also has engines, crew, and optionally also payload accommodation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Synthetic Fuels
Synthetic fuel or synfuel is a liquid fuel, or sometimes gaseous fuel, obtained from syngas, a mixture of carbon monoxide and hydrogen, in which the syngas was derived from gasification of solid feedstocks such as coal or biomass or by reforming of natural gas. Common ways for refining synthetic fuels include the Fischer–Tropsch conversion, methanol to gasoline conversion, or direct coal liquefaction. Classification and principles The term 'synthetic fuel' or 'synfuel' has several different meanings and it may include different types of fuels. More traditional definitions define 'synthetic fuel' or 'synfuel' as any liquid fuel obtained from coal or natural gas. In its Annual Energy Outlook 2006, the Energy Information Administration defines synthetic fuels as fuels produced from coal, natural gas, or biomass feedstocks through chemical conversion into synthetic crude and/or synthetic liquid products. A number of synthetic fuel's definitions include fuels produced from b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aviation Fuels
Aviation fuels are petroleum-based fuels, or petroleum and synthetic fuel blends, used to power aircraft. They have more stringent requirements than fuels used for ground use, such as heating and road transport, and contain additives to enhance or maintain properties important to fuel performance or handling. They are kerosene-based (JP-8 and Jet A-1) for gas turbine-powered aircraft. Piston-engined aircraft use leaded gasoline and those with diesel engines may use jet fuel (kerosene). By 2012, all aircraft operated by the U.S. Air Force had been certified to use a 50-50 blend of kerosene and synthetic fuel derived from coal or natural gas as a way of stabilizing the cost of fuel. Specific energy (energy per unit mass) is an important criterion in selecting fuel for an aircraft. The much higher energy storage capability of hydrocarbon fuels compared to batteries has so far prevented electric aircraft using electric batteries as the main propulsion energy store becoming viable for ...

Lighting
Lighting or illumination is the deliberate use of light to achieve practical or aesthetic effects. Lighting includes the use of both artificial light sources like lamps and light fixtures, as well as natural illumination by capturing daylight. Daylighting (using windows, skylights, or light shelves) is sometimes used as the main source of light during daytime in buildings. This can save energy in place of using artificial lighting, which represents a major component of energy consumption in buildings. Proper lighting can enhance task performance, improve the appearance of an area, or have positive psychological effects on occupants. Indoor lighting is usually accomplished using light fixtures, and is a key part of interior design. Lighting can also be an intrinsic component of landscape projects. History With the discovery of fire, the earliest form of artificial lighting used to illuminate an area were campfires or torches. As early as 400,000 years ago, fire was kindl ...

Fuel Gas
Fuel gas is any one of a number of fuels that under ordinary conditions are gaseous. Most fuel gases are composed of hydrocarbons (such as methane or propane), hydrogen, carbon monoxide, or mixtures thereof. Such gases are sources energy that can be readily transmitted and distributed through pipes. Fuel gas is contrasted with liquid fuels and from solid fuels, although some fuel gases are Liquefaction of gases, liquefied for storage or transport (for example, autogas). While their gaseous nature has advantages, avoiding the difficulty of transporting solid fuel and the dangers of spillage inherent in liquid fuels, it also has limitation. It is possible for a fuel gas to be undetected and cause gas explosion. For this reason, odorizers are added to most fuel gases. The most common type of fuel gas in current use is natural gas. Types There are two broad classes of fuel gases, based not on their chemical composition, but their source and the way they are produced: those found n ...

K-1 (airship)
The K-1 was an experimental blimp designed by the United States Navy in 1929. Due to the inability to get Congressional approval for the construction of an airship the navy used the ploy of ordering a "universal" control car (type J/K) which could be used on the J-type airships from the Naval Aircraft Factory. An order was placed with Goodyear Tire and Rubber Company for an envelope to hold "experimental gases". To complete the deception, there is no record of the US Navy assigning a serial number to the K-1, Standard Army TC type tail fins were procured from Goodyear. Unlike past Navy blimps, the control car was not suspended from external cables, but was hung from cables attached to the top of the envelope, and the car was carried flush against the envelope as in modern blimps. The control car carried bunks and a galley so that a relief crew could be carried, and was completely enclosed. The K-1 was also the first Navy blimp to have a taxi wheel. Like the Graf Zeppelin, the fuel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
History Of Manufactured Gas
The history of gaseous fuel, important for lighting, heating, and cooking purposes throughout most of the 19th century and the first half of the 20th century, began with the development of analytical and pneumatic chemistry in the 18th century. The manufacturing process for "synthetic fuel gases" (also known as "manufactured fuel gas", "manufactured gas" or simply "gas") typically consisted of the gasification of combustible materials, usually coal, but also wood and oil. The coal was gasified by heating the coal in enclosed ovens with an oxygen-poor atmosphere. The fuel gases generated were mixtures of many chemical substances, including hydrogen, methane, carbon monoxide and ethylene, and could be burnt for heating and lighting purposes. Coal gas, for example, also contains significant quantities of unwanted sulfur and ammonia compounds, as well as heavy hydrocarbons, and so the manufactured fuel gases needed to be purified before they could be used. The first attempts to manufa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
August Riedinger
August Riedinger (9 October 1845 – 15 January 1919) Augsburg city archive was a German businessman who operated gas companies in Germany and Europe and also participated in balloon manufacturing. Life Riedinger was born in 1845 as the son of the industrialist Ludwig August Riedinger in Augsburg. After six years of studies at the Zurich Polytechnic he entered his father's machinery and bronzeworks business in 1877. Richard Winkler page 574 His father died in 1879 Vogt, Wilhelm when the business had 25 gasworks in Bavaria, and another 42 in the rest of Europe and a number of gas plants for factories and public buildings. L. A. Riedinger Augsburg In 1883 Riedinger took over the business and in 1887 when the company converted to the Joint stock company , he became a member of its supervisory board. By then he had already founded the (AG United Gasworks) in Augsburg which by 1896 had grown to 17 gas work companies, for example in Bolzano, Lugano and Marburg.Frühschütz, Olive ...

Hydrogen
Hydrogen is the chemical element with the symbol H and atomic number 1. Hydrogen is the lightest element. At standard conditions hydrogen is a gas of diatomic molecules having the formula . It is colorless, odorless, tasteless, non-toxic, and highly combustible. Hydrogen is the most abundant chemical substance in the universe, constituting roughly 75% of all normal matter.However, most of the universe's mass is not in the form of baryons or chemical elements. See dark matter and dark energy. Stars such as the Sun are mainly composed of hydrogen in the plasma state. Most of the hydrogen on Earth exists in molecular forms such as water and organic compounds. For the most common isotope of hydrogen (symbol 1H) each atom has one proton, one electron, and no neutrons. In the early universe, the formation of protons, the nuclei of hydrogen, occurred during the first second after the Big Bang. The emergence of neutral hydrogen atoms throughout the universe occurred about 370,000 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alkane
In organic chemistry, an alkane, or paraffin (a historical trivial name that also has other meanings), is an acyclic saturated hydrocarbon. In other words, an alkane consists of hydrogen and carbon atoms arranged in a tree structure in which all the carbon–carbon bonds are single. Alkanes have the general chemical formula . The alkanes range in complexity from the simplest case of methane (), where ''n'' = 1 (sometimes called the parent molecule), to arbitrarily large and complex molecules, like pentacontane () or 6-ethyl-2-methyl-5-(1-methylethyl) octane, an isomer of tetradecane (). The International Union of Pure and Applied Chemistry (IUPAC) defines alkanes as "acyclic branched or unbranched hydrocarbons having the general formula , and therefore consisting entirely of hydrogen atoms and saturated carbon atoms". However, some sources use the term to denote ''any'' saturated hydrocarbon, including those that are either monocyclic (i.e. the cycloalkanes) or ...

Methane
Methane ( , ) is a chemical compound with the chemical formula (one carbon atom bonded to four hydrogen atoms). It is a group-14 hydride, the simplest alkane, and the main constituent of natural gas. The relative abundance of methane on Earth makes it an economically attractive fuel, although capturing and storing it poses technical challenges due to its gaseous state under normal conditions for temperature and pressure. Naturally occurring methane is found both below ground and under the seafloor and is formed by both geological and biological processes. The largest reservoir of methane is under the seafloor in the form of methane clathrates. When methane reaches the surface and the atmosphere, it is known as atmospheric methane. The Earth's atmospheric methane concentration has increased by about 150% since 1750, and it accounts for 20% of the total radiative forcing from all of the long-lived and globally mixed greenhouse gases. It has also been detected on other plane ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
