Colloidal Fuel
Colloidal fuel is an emulsion of powdered coal in kerosene or fuel oil. It was used in World War I aboard ships as kerosene supplies ran low. Development continued after the war, and in 1932 the Cunard liner ''RMS Scythia, Scythia'' made a round-trip transatlantic voyage partly powered by colloidal fuel containing 40% coal. Advantages over oil included cost and energy density. Colloidal fuel is denser than water, which allows it to be stored under water. References Fuels {{energy-stub ...

Emulsion
An emulsion is a mixture of two or more liquids that are normally Miscibility, immiscible (unmixable or unblendable) owing to liquid-liquid phase separation. Emulsions are part of a more general class of two-phase systems of matter called colloids. Although the terms ''colloid'' and ''emulsion'' are sometimes used interchangeably, ''emulsion'' should be used when both phases, dispersed and continuous, are liquids. In an emulsion, one liquid (the dispersed phase (matter), phase) is dispersion (chemistry), dispersed in the other (the continuous phase). Examples of emulsions include vinaigrettes, homogenized milk, liquid biomolecular condensates, and some cutting fluids for metal working. Two liquids can form different types of emulsions. As an example, oil and water can form, first, an oil-in-water emulsion, in which the oil is the dispersed phase, and water is the continuous phase. Second, they can form a water-in-oil emulsion, in which water is the dispersed phase and oil is the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coal
Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams. Coal is mostly carbon with variable amounts of other Chemical element, elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is a type of fossil fuel, formed when dead plant matter decays into peat which is converted into coal by the heat and pressure of deep burial over millions of years. Vast deposits of coal originate in former wetlands called coal forests that covered much of the Earth's tropical land areas during the late Carboniferous (Pennsylvanian (geology), Pennsylvanian) and Permian times. Coal is used primarily as a fuel. While coal has been known and used for thousands of years, its usage was limited until the Industrial Revolution. With the invention of the steam engine, coal consumption increased. In 2020, coal supplied about a quarter of the world's primary energy and over a third of its Electricity generation, electricity. Some iron and steel-maki ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kerosene
Kerosene, or paraffin, is a combustibility, combustible hydrocarbon liquid which is derived from petroleum. It is widely used as a fuel in Aviation fuel, aviation as well as households. Its name derives from the Greek (''kērós'') meaning "wax"; it was registered as a trademark by Nova Scotian, Nova Scotia geologist and inventor Abraham Pineo Gesner, Abraham Gesner in 1854 before evolving into a generic trademark. It is sometimes spelled kerosine in scientific and industrial usage. Kerosene is widely used to power jet engines of aircraft (jet fuel), as well as some rocket engines in a highly refined form called RP-1. It is also commonly used as a cooking and lighting fuel, and for fire toys such as Poi (performance art)#Fire poi, poi. In parts of Asia, kerosene is sometimes used as fuel for small outboard motors or even motorcycles. World total kerosene consumption for all purposes is equivalent to about 5,500,000 barrels per day as of July 2023. The term "kerosene" is comm ...

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] |
Bonnier Corporation
Bonnier LLC (formerly Bonnier Corporation) is an American "outdoor adventure" company that originally operated numerous U.S.-based media brands but struggled in the magazine publishing industry, leading to the decline or closure of several well-known titles. Formed in 2007 after Bonnier Group's acquisition of publishing assets from Time, today it operates events within the vertical of outdoor recreation. History The company was formed in March 2007 as the U.S. subsidiary of Bonnier Group, after it acquired the 18 magazines of the Time Warner divisions Time4 Media (owner of publications such as '' Transworld Skateboarding'') and The Parenting Group (owner of publications such as ''Parenting'') for $200 million, and combined them with its 50% stake in World Publications. In June 2009 Hachette Filipacchi sold ''American Photo, Boating,'' '' Flying,'' '' Sound & Vision,'' and '' Popular Photography'' to Bonnier. In April 2013, Bonnier sold its skiing publications, including ''Sk ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
RMS Scythia
RMS ''Scythia'' was a Cunard ocean liner. She sailed on her maiden voyage in 1921, and became a troop and supply ship during the Second World War. ''Scythia'' was the longest serving Cunard liner until 4 September 2005, when her record was surpassed by ''Queen Elizabeth 2''. History After heavy losses during the First World War, Cunard Line embarked on an ambitious building programme. It decided to build "intermediate", ships rather than the large liners it had previously employed. ''Scythia'' was the first ship in this new fleet, and building began in 1919. ''Scythia'' was built for the services between Liverpool and Queenstown in the British Isles to New York and Boston, in the United States. A luxury liner designed to appeal to American tourists, in the mid-1920s, she began sailing from New York to the Mediterranean. ''Scythia'' was requisitioned at the end of 1939, left Liverpool on 24 September 1940 with 48 children bound for Boston, sponsored by readers of the ''Bosto ...
