Chafing Fuel
Chafing fuel is a fuel used for heating food, typically placed under a chafing dish. It is usually sold in a small canister and burned directly within that canister, with or without a wick. The fuel often contains methanol, ethanol, or diethylene glycol, as these may be burned safely indoors, and produce minimal soot or odour. These fuels are also used for emergency heating, outdoor cooking, and fondue. Types of fuel The first two fuels are similar with regards to consistency, both having a gel form (viscosities can vary with brand), operating procedures, and product design. The common gel methanol or ethanol chafing fuel is contained in a steel can with a resealable plug lid in sizes based on burn times. Two-, four-, and six-hour burn times are the most common sizes of methanol and ethanol chafing fuels available. The colour of the fuel being used can also vary among manufacturers. Both ethanol and methanol have low flash points, 11–17 °C, making them highly flammable; ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chafing Dish
A chafing dish is a metal cooking or serving pan on a stand with an alcohol burner holding chafing fuel below it. It is used for cooking at table, notably in Gueridon service, or as a food warmer for keeping dishes at a buffet warm. Historically, a chafing dish (from the French ''chauffer'', "to make warm") is a kind of portable grate raised on a tripod, originally heated with charcoal in a brazier, and used for foods that require gentle cooking, away from the "fierce" heat of direct flames. The chafing dish could be used at table or provided with a cover for keeping food warm on a buffet. Double dishes that provide a protective water jacket are known as '' bains-marie'' and help keep delicate foods, such as fish, warm while preventing overcooking. History The Roman politician and writer Cicero described a "kind of saucepan of Corinthian brass", writing "This simple and ingenious vessel possesses a double bottom, the upper one holds the light delicacies . . . and the fire i ...

Candle Wick
A candle wick is usually a braided cotton that holds the flame of an oil lamp or candle. A candle wick works by capillary action, conveying ("wicking") the fuel to the flame. When the liquid fuel, typically melted candle wax, reaches the flame it then vaporizes and combusts. The candle wick influences how the candle burns. Important characteristics of the wick include diameter, stiffness, fire-resistance, and tethering. Wick types Candle wicks are normally made out of braided cotton.Franz Willhöft and Rudolf Horn "Candles" in Ullmann's Encyclopedia of Industrial Chemistry, 2000, Wiley-VCH, Weinheim. Wicks are sometimes braided flat, so that as they burn they also curl back into the flame, thus making them self-consuming. Prior to the introduction of these wicks specialty scissors were used to trim the excess wick without extinguishing the flame. Large diameter wicks typically result in a larger flame, a larger pool of melted wax, and the candle burning faster. In tea ...

Methanol
Methanol (also called methyl alcohol and wood spirit, amongst other names) is an organic chemical and the simplest aliphatic alcohol, with the formula C H3 O H (a methyl group linked to a hydroxyl group, often abbreviated as MeOH). It is a light, volatile, colourless, flammable liquid with a distinctive alcoholic odour similar to that of ethanol (potable alcohol). A polar solvent, methanol acquired the name wood alcohol because it was once produced chiefly by the destructive distillation of wood. Today, methanol is mainly produced industrially by hydrogenation of carbon monoxide. Methanol consists of a methyl group linked to a polar hydroxyl group. With more than 20 million tons produced annually, it is used as a precursor to other commodity chemicals, including formaldehyde, acetic acid, methyl tert-butyl ether, methyl benzoate, anisole, peroxyacids, as well as a host of more specialised chemicals. Occurrence Small amounts of methanol are present in normal, healthy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ethanol
Ethanol (abbr. EtOH; also called ethyl alcohol, grain alcohol, drinking alcohol, or simply alcohol) is an organic compound. It is an alcohol with the chemical formula . Its formula can be also written as or (an ethyl group linked to a hydroxyl group). Ethanol is a volatile, flammable, colorless liquid with a characteristic wine-like odor and pungent taste. It is a psychoactive recreational drug, the active ingredient in alcoholic drinks. Ethanol is naturally produced by the fermentation process of sugars by yeasts or via petrochemical processes such as ethylene hydration. It has medical applications as an antiseptic and disinfectant. It is used as a chemical solvent and in the synthesis of organic compounds, and as a fuel source. Ethanol also can be dehydrated to make ethylene, an important chemical feedstock. As of 2006, world production of ethanol was , coming mostly from Brazil and the U.S. Etymology ''Ethanol'' is the systematic name defined by the ...

Diethylene Glycol
Diethylene glycol (DEG) is an organic compound with the formula (HOCH2CH2)2O. It is a colorless, practically odorless, and hygroscopic liquid with a sweetish taste. It is a four carbon dimer of ethylene glycol. It is miscible in water, alcohol, ether, acetone, and ethylene glycol. DEG is a widely used solvent.Siegfried Rebsdat and Dieter Mayer "Ethylene Glycol" in Ullmann's Encyclopedia of Industrial Chemistry, 2002, Wiley-VCH, Weinheim.. It can be a contaminant in consumer products; this has resulted in numerous epidemics of poisoning since the early 20th century. Preparation DEG is produced by the partial hydrolysis of ethylene oxide. Depending on the conditions, varying amounts of DEG and related glycols are produced. The resulting product is two ethylene glycol molecules joined by an ether bond. "Diethylene glycol is derived as a co-product with ethylene glycol (MEG) and triethylene glycol. The industry generally operates to maximize MEG production. Ethylene glycol is b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Soot
Soot ( ) is a mass of impure carbon particles resulting from the incomplete combustion of hydrocarbons. It is more properly restricted to the product of the gas-phase combustion process but is commonly extended to include the residual pyrolysed fuel particles such as coal, cenospheres, charred wood, and petroleum coke that may become airborne during pyrolysis and that are more properly identified as cokes or char. Soot causes various types of cancer and lung disease. Sources Soot as an airborne contaminant in the environment has many different sources, all of which are results of some form of pyrolysis. They include soot from coal burning, internal-combustion engines, power-plant boilers, hog-fuel boilers, ship boilers, central steam-heat boilers, waste incineration, local field burning, house fires, forest fires, fireplaces, and furnaces. These exterior sources also contribute to the indoor environment sources such as smoking of plant matter, cooking, oil lamps, candles, ...

Fondue
Fondue (, , ) is a Swiss melted cheese dish served in a communal pot ( ''caquelon'' or fondue pot) over a portable stove () heated with a candle or spirit lamp, and eaten by dipping bread into the cheese using long-stemmed forks. It was promoted as a Swiss national dish by the Swiss Cheese Union (Schweizerische Käseunion) in the 1930s, and was popularized in North America in the 1960s. Since the 1950s, the term "fondue" has been generalized to other dishes in which a food is dipped into a communal pot of liquid kept hot in a fondue pot: chocolate fondue, ''fondue au chocolat'', in which pieces of fruit or pastry are dipped into a melted chocolate mixture, and ''fondue bourguignonne'', in which pieces of meat are cooked in hot oil or broth. Etymology The word ''fondue'' is the feminine passive past participle of the French verb 'to melt' used as a noun. It is first attested in French in 1735, in Vincent La Chapelle's ''Cuisinier moderne'',Vincent la Chapelle, ''Le cuisinier ...

Flammable
A combustible material is something that can burn (i.e., ''combust'') in air. A combustible material is flammable if it ignites easily at ambient temperatures. In other words, a combustible material ignites with some effort and a flammable material catches fire immediately on exposure to flame. The degree of flammability or combustibility in air depends largely upon the volatility of the material - this is related to its composition-specific vapour pressure, which is temperature dependent. The quantity of vapour produced can be enhanced by increasing the surface area of the material forming a mist or dust. Take wood as an example. Finely divided wood dust can undergo explosive combustion and produce a blast wave. A piece of paper (made from wood) catches on fire quite easily. A heavy oak desk is much harder to ignite, even though the wood fibre is the same in all three materials. Common sense (and indeed scientific consensus until the mid-1700s) would seem to suggest that ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
