01-10-2020· This paper presents a history of coal combustion char nomenclature, classification, and petrography. A synopsis of the combustion of coal is developed to contextualise the subject and introduce the importance of devolatilisation, the formation of char, and its combustion, as well as the relationships between the properties of coal and the conditions of devolatilisation and between the
Pearson Coal Petrography provides microscopic evaluations of coking coals, steam coals, metallurgical cokes, and carbons, from state-of-the-art laboratories located in Canada, the United States, and Australia. Vitrinite Reflectance.
Coal can also be cut into thin sections, as in mineral and rock petrography. A thin section is a thinly cut sample, which is epoxied on to a thin glass plate. The sample side is then ground down and polished to the point at which light is visible through the glass and sample, which allows petrographers to see great details in the samples.
Petrography is used by coal-producers to evaluate the nature of coal deposits, to confirm the quality of vessel or train cargoes, and to show the uniqueness of a specific product relative to another. Steel producers use petrography as an aid in the design of coking coal blends, to help in trouble-shooting problem-cokes, and to confirm the nature of vessel or train cargoes.

Coal Petrography: The Study of Macerals. The branch of science concerned with the visible structure of coal is coal petrology or petrography. The structure may be examined visually by the unaided eye or by an optical microscope. Marie Stopes, a British scientist, founded the discipline of coal petrography.
Coal petrography is performed by examining polished specimens of minus 20 mesh prepared coal. Rank is determined by measuring the percent reflectance of the maceral vitrinite. Type is determined using a point count procedure to obtain the volume percent of the various coal
The Talcher project will produce 1.27 million tonnes per annum of neem-coated urea through gasification of a mixed feedstock comprising of high ash Indian coal and petcoke. TFL has been allotted northern part of the North Arkhapal mine as a captive asset for meeting its coal requirements and petcoke shall be sourced from the Paradip refinery of Indian Oil.
COAL PETROGRAPHY Coal petrography is a microscopic technique used to determine a coals rank (degree of coalification) and type (amount and type of macerals) on polished specimens of minus 20 mesh prepared coal. Petrography is used as a tool to evaluate bituminous coals and coal blends in terms of their ability to produce blast furnace coke.

Talcher also named as City of Black Diamond or Coal City of Odisha is one of the fastest growing industrial and coal hubs in the state. Because of its huge coal reserves, the city has been ranked among the highest in terms of GDP in Odisha. It is also one of the 4 sub-divisions of Angul district in the Indian state of Odisha.Situated on the right bank of the river Brahmani, it is one of the

coal fractions became increasingly similar in many (but not all) properties, which has led some to con-sider the existence of a ‘coal molecule’. Coal petrology has been fundamental to the devel-opment of our understanding of coal origins and formation.

Talcher Coalfield covers an area of 500 km 2 (190 sq mi). The coal is of lower grade containing only about 35 per cent of fixed carbon, 70 per cent volatile matter and 25 per cent ash content. [2] As of 2011, nearly one hundred thousand tonnes of coal is dispatched daily to power stations in Odisha,Tamil Nadu,Andhra Pradesh,West Bengal and other parts of India.
