Tea coal disease (Neocapnodium theae Hara) is a disease that occurs in tea and is caused by the presence of Neocapnodium theae Hara, or insects such as whitefly, scale, and aphid.It causes the leaves to wither and die. At the initial stage of the disease, small black circular or irregular spots appear on the surface of the leaves, which …
Bituminous coals are black, shiny, and generally hard.They are a medium-rank coal. Bituminous coals generally have calorific values above 11,500 Btu/lb and volatile matter below 14% (ASTM, Jackson, 1997). In the Illinois Basin (and western Kentucky), however, the lower rank end of what are termed bituminous coals in the United States …

Coal, one of the most important primary fossil fuels, a solid carbon-rich material, usually brown or black, that most often occurs in stratified sedimentary deposits, which may later be subjected to high temperatures and pressures during mountain building, resulting in the development of anthracite and even graphite.
Lignite, generally yellow to dark brown or rarely black coal that formed from peat at shallow depths and temperatures lower than 100 °C (212 °F). It is the first product of coalification and is intermediate between peat and subbituminous coal according to the coal classification used in the United
A discussion of the system used for classifying coals in the United States and the international systems of coal classification follows. In the ASTM International (previously the American Society for Testing and Materials) Standard D388, Classification of Coals by Rank [2], coals are classified according to their degree of metamorphism (i.e ...
A fourth coal type classification is directed towards coals of lignite rank which are sometimes referred to as 'brown' coal. At very low ranks, coal types manifest themselves as color variations, ranging from dark brown to a 'pale' brown hue (George, 1982) ().In part, these color variations are the result of the ratio of preserved plant material to resinous …
Conclusions This study revealed the classification potential of tea coal disease based on RGB and hyperspectral imaging, which can provide an accurate, non-destructive, and efficient classification method for monitoring tea coal disease. Keywords Tea coal disease, RGB, Hyperspectral, Machine learning, Deep learning, Classification
It is a peat that has been transformed into a rock, and that rock is a brown-black coal. Lignite sometimes contains recognizable plant structures. By definition it has a heating value of less than 8300 British Thermal Units per pound on a mineral-matter-free basis. It has a carbon content of between 60 and 70% on a dry ash-free basis.
CLASSIFICATION OF COAL Numerous system of coal classification has been proposed by different authors since the later part of the 19th century. Most of the classifications are based on the physical, chemical and ... Cannel coal is black and dull, sometimes with a rather greasy lustre.
