Fuel Gas
Fuel gas is one of a number of fuels that under ordinary conditions are gaseous. Most fuel gases are composed of hydrocarbons (such as methane and propane), hydrogen, carbon monoxide, or mixtures thereof. Such gases are sources of energy that can be readily transmitted and distributed through pipes. Fuel gas is contrasted with liquid fuels and solid fuels, although some fuel gases are Liquefaction of gases, liquefied for storage or transport (for example, autogas and Liquefied petroleum gas, liquified petroleum gas). 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 limitations. It is possible for a fuel gas to be undetected and cause a 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 of fuel gas There are two broad classes of fuel gases, based not on their chemical composition ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fuel Oil
Fuel oil is any of various fractions obtained from the distillation of petroleum (crude oil). Such oils include distillates (the lighter fractions) and residues (the heavier fractions). Fuel oils include heavy fuel oil (bunker fuel), marine fuel oil (MFO), furnace oil (FO), gas oil (gasoil), heating oils (such as home heating oil), diesel fuel, and others. The term ''fuel oil'' generally includes any liquid fuel that is burned in a furnace or boiler to generate heat ( heating oils), or used in an engine to generate power (as motor fuels). However, it does not usually include other liquid oils, such as those with a flash point of approximately , or oils burned in cotton- or wool-wick burners. In a stricter sense, ''fuel oil'' refers only to the heaviest commercial fuels that crude oil can yield, that is, those fuels heavier than gasoline (petrol) and naphtha. Fuel oil consists of long-chain hydrocarbons, particularly alkanes, cycloalkanes, and aromatics. Small molecul ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chartres Gaslights NOLA
Chartres () is the prefecture of the Eure-et-Loir department in the Centre-Val de Loire region in France. It is located about southwest of Paris. At the 2019 census, there were 170,763 inhabitants in the metropolitan area of Chartres (as defined by the INSEE), 38,534 of whom lived in the city ( commune) of Chartres proper. Chartres is famous worldwide for its cathedral. Mostly constructed between 1193 and 1250, this Gothic cathedral is in an exceptional state of preservation. The majority of the original stained glass windows survive intact, while the architecture has seen only minor changes since the early 13th century. Part of the old town, including most of the library associated with the School of Chartres, was destroyed by Allied bombs in 1944. History Chartres was one of the principal towns in Gaul of the Carnutes, a Celtic tribe. In the Gallo-Roman period, it was called ''Autricum'', name derived from the river ''Autura'' (Eure), and afterwards ''civitas Carnutum ...

Blast Furnace Gas
Blast furnace gas (BFG) is a by-product of blast furnaces that is generated when the iron ore is redox, reduced with coke (fuel), coke to metallic iron. It has a very low heating value, about 3.5 MJ/m3 (93 BTU/cu.ft), because it consists of about 51 vol% nitrogen and 22 vol% carbon dioxide, which are not flammable. The rest amounts to around 22 vol% carbon monoxide, which has a fairly low heating value already and 5 vol% hydrogen. Per ton of steel produced via the blast furnace route, 2.5 to 3.5 tons of blast furnace gas is produced. It is commonly used as a fuel within the steel works, but it can be used in boilers and power plants equipped to burn it. It may be combined with natural gas or coke oven gas before combustion or a flame support with richer gas or oil is provided to sustain combustion. Atmospheric particulate matter, Particulate matter is removed so that it can be burned more cleanly. Blast furnace gas is sometimes gas flare, flared without generating heat o ...

Biogas
Biogas is a gaseous renewable energy source produced from raw materials such as agricultural waste, manure, municipal waste, plant material, sewage, green waste, Wastewater treatment, wastewater, and food waste. Biogas is produced by anaerobic digestion with anaerobic organisms or methanogens inside an Anaerobic digestion, anaerobic digester, biodigester or a bioreactor. The gas composition is primarily methane () and carbon dioxide () and may have small amounts of hydrogen sulfide (), moisture and siloxanes. The methane can be combusted or oxidized with oxygen. This energy release allows biogas to be used as a fuel; it can be used in fuel cells and for heating purpose, such as in cooking. It can also be used in a gas engine to convert the energy in the gas into electricity and heat. After removal of carbon dioxide and hydrogen sulfide it can be compressed natural gas, compressed in the same way as natural gas and used to power Alternative fuel vehicle, motor vehicles.

Biofuel
Biofuel is a fuel that is produced over a short time span from Biomass (energy), biomass, rather than by the very slow natural processes involved in the formation of fossil fuels such as oil. Biofuel can be produced from plants or from agricultural, domestic or industrial Biodegradable waste, bio waste. Biofuels are mostly used for transportation, but can also be used for heating and electricity. Biofuels (and bioenergy, bio energy in general) are regarded as a renewable energy source. The use of biofuel has been subject to criticism regarding the "food vs fuel" debate, varied assessments of their Sustainable biofuel, sustainability, and ongoing deforestation and biodiversity loss as a result of biofuel production. In general, biofuels emit fewer greenhouse gas emissions when burned in an engine and are generally considered carbon-neutral fuels as the carbon emitted has been captured from the atmosphere by the crops used in production. However, life-cycle assessments of biofue ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wood
Wood is a structural tissue/material found as xylem in the stems and roots of trees and other woody plants. It is an organic materiala natural composite of cellulosic fibers that are strong in tension and embedded in a matrix of lignin that resists compression. Wood is sometimes defined as only the secondary xylem in the stems of trees, or more broadly to include the same type of tissue elsewhere, such as in the roots of trees or shrubs. In a living tree, it performs a mechanical-support function, enabling woody plants to grow large or to stand up by themselves. It also conveys water and nutrients among the leaves, other growing tissues, and the roots. Wood may also refer to other plant materials with comparable properties, and to material engineered from wood, woodchips, or fibers. Wood has been used for thousands of years for fuel, as a construction material, for making tools and weapons, furniture and paper. More recently it emerged as a feedstock for the production ...

Wood Gas
Wood gas is a fuel gas that can be used for furnaces, stoves, and vehicles. During the production process, biomass or related carbon-containing materials are gasified within the oxygen-limited environment of a wood gas generator to produce a combustible mixture. In some gasifiers this process is preceded by pyrolysis, where the biomass or coal is first converted to char, releasing methane and tar rich in polycyclic aromatic hydrocarbons. In stark contrast with synthesis gas, which is almost pure mixture of wood gas ''also'' contains a variety of organic compound ("distillates") that require scrubbing for use in other applications. Depending on the kind of biomass, a variety of contaminants are produced that will condense out as the gas cools. When producer gas is used to power cars and boats or distributed to remote locations it is necessary to scrub the gas to remove the materials that can condense and clog carburetors and gas lines. Anthracite and coke are preferred for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Syngas
Syngas, or synthesis gas, is a mixture of hydrogen and carbon monoxide in various ratios. The gas often contains some carbon dioxide and methane. It is principally used for producing ammonia or methanol. Syngas is combustible and can be used as a fuel. Historically, it has been used as a replacement for gasoline when gasoline supply has been limited; for example, wood gas was used to power cars in Europe during WWII (in Germany alone, half a million cars were built or rebuilt to run on wood gas). Production Syngas is produced by steam reforming or partial oxidation of natural gas or liquid hydrocarbons, or coal gasification. : : : Steam reforming of methane is an endothermic reaction requiring 206 kJ/mol of energy: : In principle, but rarely in practice, biomass and related hydrocarbon feedstocks could be used to generate biogas and biochar in waste-to-energy gasification facilities. The gas generated (mostly methane and carbon dioxide) is sometimes described as ''syng ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Producer Gas
Producer gas is a fuel gas manufactured by blowing air and steam simultaneously through a coke or coal fire. It mainly consists of carbon monoxide (CO), hydrogen (H2), as well as substantial amounts of nitrogen (N2). The caloric value of the producer gas is low (mainly because of its high nitrogen content), and the technology is obsolete. Improvements over producer gas, also obsolete, include water gas, where the solid fuel is treated intermittently with air and steam, and, far more efficiently, synthesis gas, where the solid fuel is replaced with methane. In the US, producer gas may also be referred to by other names based on the fuel used for production, such as wood gas. Producer gas may also be referred to as suction gas, referring to the way the air was drawn into the gas generator by an internal combustion engine. Production Producer gas is generally made from coke, or other carbonaceous material such as anthracite coal. Air is passed over the red-hot carbonaceous fu ...

Coke (fuel)
Coke is a grey, hard, and porous coal-based fuel with a high carbon content. It is made by heating coal or petroleum in the absence of air. Coke is an important industrial product, used mainly in iron ore smelting, but also as a fuel in stoves and forges. The unqualified term "coke" usually refers to the product derived from low-ash and low-sulphur bituminous coal by a process called coking. A similar product called petroleum coke, or pet coke, is obtained from crude petroleum in oil refinery, petroleum refineries. Coke may also be formed naturally by geology, geologic processes.B. Kwiecińska and H. I. Petersen (2004): "Graphite, semi-graphite, natural coke, and natural char classification — ICCP system". ''International Journal of Coal Geology'', volume 57, issue 2, pages 99-116. It is the residue of a destructive distillation process. Production Industrial coke furnaces The industrial production of coke from coal is called coking. The coal is baked in an airless k ...

Water Gas
Water gas is a kind of fuel gas, a mixture of carbon monoxide and hydrogen. It is produced by "alternately hot blowing a fuel layer okewith air and gasifying it with steam". The caloric yield of the fuel produced by this method is about 10% of the yield from a modern syngas plant. The coke needed to produce water gas also costs significantly more than the precursors for syngas (mainly methane from natural gas), making water gas technology an even less attractive business proposition. Production Synthesis gas is made by passing steam over a red-hot carbon fuel such as coke: : (Δ''H'' = +131 kJ/mol) The reaction is endothermic, so the fuel must be continually re-heated to maintain the reaction. To do this, an air stream, which alternates with the vapor stream, is introduced to combust some of the carbon: : (Δ''H'' = −393 kJ/mol) Theoretically, to make 6 L of water gas, 5 L of air is required. Alternatively, to prevent contamination with nitrogen, energy can be p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coal Gas
Coal gas is a flammable gaseous fuel made from coal and supplied to the user via a piped distribution system. It is produced when coal is heated strongly in the absence of air. Town gas is a more general term referring to manufactured gaseous fuels produced for sale to consumers and municipalities. The original coal gas was produced by the coal gasification reaction, and the burnable component consisted of a mixture of carbon monoxide and hydrogen in roughly equal quantities by volume. Thus, coal gas is highly toxicity, toxic. Other compositions contain additional Calorific Value, calorific gases such as methane, produced by the Fischer–Tropsch process, and volatile hydrocarbons together with small quantities of non-calorific gases such as carbon dioxide and nitrogen. Prior to the development of natural gas supply and transmission—during the 1940s and 1950s in the United States and during the late 1960s and 1970s in the United Kingdom and Australia—almost all gas for fu ...
