Topic: Coke (fuel)


  
  Coke (fuel)
Coke is a solid carbonaceous residue derived from low-ash, low-sulfur bituminous coal.
Coke is used as a fuel and as a reducing agent in smelting iron ore in a blast furnace.
The use of coke as a fuel was pioneered in 17th century England in response to the ever-growing problem of European deforestation.

 Fuel Encyclopedia @ LaunchBase.org (Launch Base)   (Site not responding. Last check: 2007-10-20)
Fuel is any material that is capable of releasing energy when its chemical structure is changed or converted.
For example, a fuel value is used to quantify fuel's potential energy.
The application of energy released from fuels ranges from heat to cooking and from powering weapons to propulsion and generation of electricity.

 Coal - Encyclopedia, History, Geography and Biography
Coal is a fossil fuel extracted from the ground by underground mining or open-pit mining (surface mining).
Coal is coked at temperatures between 450 and 700 °C compared to 800 to 1000 °C for metallurgical coke.
Coke is a solid carbonaceous residue derived from low-ash, low-sulfur bituminous coal from which the volatile constituents are driven off by baking in an oven without oxygen at temperatures as high as 1,000 °C (2,000 °F) so that the fixed carbon and residual ash are fused together.

 coke. The Columbia Encyclopedia, Sixth Edition. 2001-05
In the form of oven coke it is primarily used when a porous fuel with few impurities and high carbon content is desired, as in the blast furnace to make iron.
Coke is also used in other metallurgical processes, such as the manufacture of ferro-alloys, lead, and zinc, and in kilns to make lime and magnesium.
In nonrecovery coke plants, originally referred to as beehive ovens, the coal is carbonized in large oven chambers; the partially combusted gases collect in a common tunnel and exit via a stack.

 Chapter 4. Impacts of Electric Power Industry Restructuring on Crude-Oil-Derived Fuels
Although coke's fuel properties are different from those of coal, it is being blended with coal in some facilities without the requirement of substantial equipment modifications.
Because utility residual fuel use, including that of high-sulfur residual fuel, has been exhibiting a downward trend, and there is a general move to reduce sulfur in all fuels, the market for high-sulfur products is shrinking.
Refiners are beginning to look to gasification as a means of using high-sulfur, high-metals residual fuel and coke, along with a number of refinery waste streams, as feedstocks to produce synthetic gas, which could then be used to produce power, steam, and a variety of chemicals (such as hydrogen and ammonia) of use to refineries.

 Frank M. Gentry: The Technology of Low Temperature Carbonization ~ Chap. 4: Low Temperature Coke
Coke from the Maclaurin (188) retort was carbonized by internal heating through the agency of the sensible heat of producer gas.
These cokes were made at 900° C. Experiments by Audibert and Delmas (103) indicated that all coals examined by them attained a maximum strength at a given rate of heating, rising rapidly to this maximum as the rate of heating increases and declining slowly from the maximum as the rate of heating is further increased.
It was demonstrated that the fuel was smokeless and that it evaporated from 8.5 to 12.8 pounds of water per pound of fuel per hour, from and at 212° F, when fired at rates ranging from 100 pounds to 27 pounds of fuel per hour per square foot of grate surface, respectively.

A cremation oven's fuel consumption depends in the main on the manner of the oven's construction, the cremation process, the frequency of cremations, the state of the bodies, and the operation of the oven.
The Coke Consumption of the Topf Cremation Ovens of Auschwitz and Birkenau
Since the minimum coke requirement for the cremation of the bodies of the 21,850 registered inmates was 420,000 kg (926,000 lbs), the bodies of the alleged 102,968 gassing victims would have had to be cremated with the remaining 98,500 kg (217,200 lbs) of coke.

 Ketchum: Review of Low Temperature Carbonization Processes [ Karrick, Hayes, Rexco, NFC &c.]
Fuel Gas: Fuel gas, from LTC of coal, varies both in quantity and quality depending on the composition of the raw coal, and also upon the process and temperature of carbonization.
Coke: The yield is given in percent of coal as carbonized, without correction for a very small amount of moisture from the atmosphere during 24-hour period when coke was being tested and prepared for chemical analysis.
Solid, liquid or gaseous fuel is burned either in a chamber which surrounds the retort proper or in a series of heating cells built on the outside of the retort wall.

Prices for raw materials such as coke and scrap have more than doubled from last year, mainly because China is buying all it can find to feed its rapidly growing steel industry, putting a squeeze on makers elsewhere in the world.
Coke is burned to melt iron ore into molten iron in a blast furnace.
That makes maintaining in-house coke production extremely important for ISG and other companies that can't afford even a short let-up in coke supply: Steel prices and demand are surging, giving the once-ailing industry a prime opportunity to boost profits.

 Ford Foundation: Potential Fuel Effectiveness in Industry - 40
Coke is the primary fuel used in the blast furnace for the reduction of iron ore into pig iron.
Present U.S. practice is to quench the coke rapidly with water to prevent it from oxidizing and to cool it for transfer to the blast furnace, a process which produces dust-laden pollution and contaminated water.
In addition to coke, the coking process yields coke oven gas and tar products which leave the oven at 1100—1300°F. A representative fuel balance for 1969 average practice for the coking process is given in Table 5-1-1.

 EH.Net Encyclopedia: US Coal Industry in the Nineteenth Century
The fuel needs of the federal army and navy, along with their military suppliers, promised a significant increase in the demand for coal.
The late nineteenth century saw the emergence of coke -- a form of processed bituminous coal in which impurities are "baked" out under high temperatures -- as a powerful fuel in the iron and steel industry.
The successful incorporation of new mining methods and the emergence of coke as a major fuel source served as both a blessing and a curse to mining firms.

is funded by solid fuel producers and distributors and was established to encourage greater awareness of the benefits of domestic solid fuel heating among the general public.
Medical research has also shown that solid fuel heating can reduce the risk of hay fever, asthma and eczema.Homes with solid fuel heating are better ventilated than those with other forms of heating; the very use of a chimney will induce ventilation into a home drawing in fresh air and removing the 'polluted' air.
To get the best out of this 21st century fuel and reap the maximum benefits in terms of fuel efficiency, it is important to choose the solid fuel that is most suitable for use in your appliance.

 Cupola Furnace - Basics of Foundry Melting Furnaces
The charge consists of alternate layers of the metal to be melted, coke fuel and limestone flux.
Once the coke bed is ignited and of the required height, alternate layers of metal, flux and coke are added until the level reaches the charged doors.
As the metal is melted and fuel consumed, additional charges are added to maintain a level at the charging door and provide a continuous supply of molten iron.

 MacNN | Tech: Coke music site, 64-bit notebooks, fuel cells..
The problem with DMFC fuel cells is that they typically run at 25% efficiency, and they require the methanol to be diluted with water, so they need a little water treatment plant to recycle the water back if they're going to use high concentrations of methanol.
I work on reformed methanol fuel cells, which require a somewhat high temp (500F) reformer to convert methanol and water into hydrogen and carbon dioxide.
For devices that require 10 watts or more, this scheme seems to work better- we can operate the fuel cells at 50% efficiency or higher.
