International Journal of Coal Geology's journal/conference profile on Publons, with 81 reviews by 27 reviewers working with reviewers, publishers, institutions, and funding agencies to turn peer review into a measurable research output.
Coal type is a specific geologic classification based on the general appearance of coal. Most coals have internal layering, called banding. Coal types, and subsets of types, called lithotypes, are based on the presence or absence of banding, and the brightness or dullness of individual bands.

Abstract Coal will be a dominant energy source in both developed and developing countries for at least the first half of the 21st century. Environmental problems associated with coal, before mining, during mining, in storage, during combustion, and postcombustion waste products are well known and are being addressed by...
The Journal of Consumer Culture is an established journal, supporting and promoting the continuing expansion in interdisciplinary research focused on consumption and consumer culture, opening up debates and areas of exploration. Global in perspective and drawing on both theory and empirical research, the journal reflects the need to engage critically with modern consumer culture and to .
Carbon capture and storage technologies can reduce potential emissions. The conversion to a liquid or a gas creates a fuel that burns cleaner as well, which limits the production of ash and other byproducts that are created by the combustion process. 6. Coal can be used with renewables to reduce emissions.
Coalfired power plant development started with the introduction of the first dynamo built for power generation in 1866 by Werner von Siemens, illustrated in Figure 11. In 1882, Thomas Edison built the first central power station in New York.

Abstract. A major shift to coal as an energy source adjunct with more stringent air quality standards will result in the increasing production of vast quantities of the already difficulttodispose coal residues in the United States. Since coal residues contain potentially hazardous substances, improper handling and disposal could cause undesirable...
Environmental impacts of coal. Many of the heavy metals released in the mining and burning of coal are environmentally and biologically toxic elements, such as lead, mercury, nickel, tin, cadmium, antimony, and arsenic, as well as radio isotopes of thorium and strontium.
However, that was before some of the coal cars were sold. In its 2016 announcement, the railroad corporation stated that it offered the aluminum coal hoppers to Usibelli for purchase, but the coal company declined. The railroad corporation does still maintain a fleet of coal cars.

Coal tar is used as fuel either for heating the gas retorts or for other purposes. Coal tar is employed for painting wood, iron, brick work or stone as a preventive against the influence of weather or the far more potent action of corrosive chemicals. Coal tar should not be used for tarring the wood work and ropes
We've all paid a utility bill or purchased gasoline. Those represent the direct costs of fossil fuels; money paid out of pocket for energy from coal, natural gas, and oil.. But those expenses don't reflect the total cost of fossil fuels to each of us individually or to society as a whole.
Abstract. The weight percent moisture, volatile matter, fixed carbon, and ash content are determined for each sample and comparisons are made. Proximate analysis is performed on a coal sample from a local electric utility. From the weight percent sulfur found in the coal (determined by a separate procedure—the Eschka method) and the ash content,...
