PREQUALIFICATION OF LICENSORS OF COAL GASIFICATION TECHNOLOGY FOR PROPOSED COAL BASED AMMONIA – UREA COMPLEX AT TALCHER, DISTRICT ANGUL, ODISHA, INDIA INTRODUCTION Talcher Fertilizers Limited (TFL) is a consortium of GAIL (India) Limited, Coal India Limited (CIL), Rashtriya Chemicals and Fertilizers Limited (RCF)
Coal petrography is a microscopic technique used to determine a coal''s rank (degree of coalification) and type (amount and category of macerals). Producers and users of coal and coke rely on SGS, an industry leader in coal petrology, for independent, globally recognized coal petrographic analysis. Accurate petrographic analysis is an ...
Coal petrography can be described broadly as the microscopic determination of the organic and inorganic constituents of coal and the degree of metamorphosis, or rank, which the coal has obtained. Petrographic constituents can be directly correlated to important properties affecting the combustion behaviour of coal.

Coal Petrography the description of the components of coal as studied macroscopically and in thin and polished sections under the microscope. The founders of coal petrography in the USSR were Iu. A. Zhemchuzhnikov and M. D. Zalesskii. Outside the USSR, R. Thiessen of the USA and M. Stopes of Great Britain made seminal contributions to the development of ...
Aug 21, 2019· Bhubaneswar: Staterun power generator NTPC''s Kaniha unit in Angul district of Odisha is facing coal shortage due to a strike by villagers at the Kaniha Open Cast Project (KOCP). The coal supply to the Kaniha unit from KOCP has stopped since August 18 due to a strike by villagers at the mines end, an NTPC statement said on Tuesday.
In the present study an attempt has been made to characterize the coals of Talcher coalfield employing petrographic and geochemical techniques on a large number of coal samples. Pillar coal samples were collected from all the six workable coal seams, which occur in the Karharbari (SeamI) and the Barakar (Seams II, III, IV, V and IX) formations.
TALCHER. The oldest washery of GCMPL got commissioned in 2003, at Talcher (odisha). Current standing order is with the Andhra Pradesh Power Generation Corporation (APGENCO) for a quantity of MTPA of raw coal. Washing technology used here is Dense/Heavy Media, Pneumatic Jig, HM Cyclone, Classify Cyclone.
These diagrams illustrate that Provincialism plays a big part in dictating the quality of a coal (Fig. 2, below). For example, coal 50123, from Australia, and 67142, from Canada, both have the same Volatile Matter content of about 23% DAF, yet their Romax and Vitrinite content are quite different.

Coal petrography is the study of the organic constituents of sedimentary rocks, originally, by optical microscopy of thin sections (transmitted light) or of polished blocks (reflected light) (Unsworth et al., 1991). Coal macerals have different colours and fluorescence intensities and can be .
Bhubaneswar: At least 60,000 tonne coal could not be supplied to various consumers due to continuous stoppage of coal despatch from Balram Open Cast Project in Talcher coalfields of Mahanadi Coalfields Limited (MCL) on Friday. The residents of Danara village has stopped coal supply from the mines ...

Petrography enables the optical consideration of coal and carbon via which the evolution of char structures, and hence the changes during the carbon conversion process, can be determined. The maceral content significantly affects char formation, which is also affected by the role of temperature, pressure, residence time, and particle size (Zhuo et al., 2000).
The 12 coal channel samples were obtained from 5 coal beds that span about 244 m or 800 ft of stratigraphic section in the Pocahontas and New River Formations of Early Pennsylvanian age.
Determining some attributes of coal may require microscopic examination, called petrography, which is a subset of petrology. Scientists who examine coal under a microscope are called coal petrographers. In one type of petrography, coal is ground down into fine particles, combined with epoxy, and put into molds to form a pellet.
The study of coal maceral constituents based on the structure is important to know the coal type. Two basic systems of petrography have been used over the years, the StopesHeerlen (SH) and the Thiessen Bureau of Mines systems. The former, almost universally now accepted, was developed by Marie C Stopes, a British Coal Scientist.
Talcher Fertilizers Limited a Joint Venture Company (JVC) promoted by GAIL, CIL, RCF and FCIL was formed to revive FCIL''s Talcher fertilizer unit in the Angul district of Odisha. Currently GAIL holds % in this JVC. The company plans to produce approx. MMTPA of urea using coal as feedstock.
This section is composed of photomicrographs of just a few of the most common macerals in coal and is meant only to serve as an introduction to coal petrography. Vitrinite Macerals. Vitrinite macerals are derived from the cell wall material (woody tissue) of plants, which are chemically composed of the polymers, cellulose and lignin.
