COAL AND COKE TESTING

Coal is a fossil fuel that is formed from the accumulation of dead plant matter in swamps and peat bogs which is converted into different forms like Lignite, Sub-Bituminous, Bituminous, and Anthracite, through biological and geological processes over a period of time. It has many important uses worldwide like electricity generation, steel production to household cooking purposes.
Different types of coal have different uses. Steam coal, also known as Thermal Coal, is mainly used in power generation. Coking coal, also known as metallurgical coal, is mainly used in steel production. Gradation is very important for the specific use of coal. The gradations of coal are done on the basis of its Calorific Value, Ash Content, and Moisture Percent.
It is therefore essential to determine the grade of the coal with respect to the quality aspects prior to sell or purchase or use. EFRAC is a NABL accredited Laboratory offering a complete range of “Coal & Coke” analysis to meet all kinds of requirements for Producers, Exporters, Transporters, and Users.

[Coal and its different forms like Lignite, Sub-Bituminous, Bituminous, and Anthracite is a fossil fuel formed underground from the conversion of organic matter through biological and geological processes over millions of years. Currently, Power Generation & Steel Making industries are the biggest consumers of Thermal and Metallurgical grades of coal respectively, worldwide. Correct gradation of coal, based on definitive parameters such as Calorific Value, Ash Content, and Moisture Percentage is critical for a specific end-use.  Incorrect assessment of these parameters leading to its purchase & use thereafter can damage costly equipment permanently, lead to total rejection of output on grounds of unacceptable Quality and add unnecessary costs on transportation, storage & manpower time.

EFRAC, a NABL accredited Laboratory arrayed with the latest equipment, trained Techno-scientific personnel, and in-depth expertise affords the complete range of “Coal & Coke” analyses so as to fulfill the requirements for Producers, Exporters, Transporters, and end-users.]
