What is the difference between coking coal mines and non-coking coal mines?
coking coal required for production of coke which is used in steel industries and non coking coal required for thermal power plants for steam production. coking coal required for production of coke which is used in steel industries and non coking coal required for thermal power plants for steam production.
What are the differences between coking coal and non-coking coal?
Coals as straight or in blend which on carbonization produce hard coke are known as coking coals. Depending upon coking capacity, coking coals are divided into prime or hard coking coal, medium or soft coking coals and weakly or semi-soft coking coals. The coking coals are classified based on CSN, LTGK coke type, gieseler fluidity, vitrinite contents, mean maximum reflectace of vitrinite etc. On the other hand, coals which on carbonization produce powery mass are known as non-coking coals. Coals having CSN 0-1 and LTGK coke type of A and B are non coking coals. Dr. Tamal Kanti Das DGM, RDCIS, SAIL, Ranchi, India
Why Did Darby process of coking to remove chemical impurities from coal 1713?
Darby used the process of coking to remove chemical impurities from coal in 1713 because it produced a higher quality fuel with fewer impurities that burned more efficiently. Coking involves heating coal in the absence of oxygen to drive off volatile compounds and leave behind a cleaner, more pure form of carbon. This helped improve the efficiency of iron smelting and other industrial processes that relied on coal as a fuel source.
How much coking coal is needed to produce one ton of steel?
Approximately 770 kilograms of coking coal are needed to produce one ton of steel through the traditional blast furnace method. The coking coal is used as a fuel and as a reducing agent in the steelmaking process, where it helps convert iron ore into molten iron in the blast furnace.
When was Bharat Coking Coal Limited created?
Bharat Coking Coal Limited was created in 1972.
What is coke-drum unheading?
Coke drum unheading in general can be explained as follows.When coke is being formed in the coke drum the unheading is a means of isolating the drum from the decoking device.After coking process is complete the unheading devices ( at top and bottom of the drum ) are opened and by hydraulic or other means the coke formed is separated from the drum and further handled and conveyed.The drum is again ready for coking and the unheading devices are closed. The process of coking and decoking are batch processes and take place over a period of about 24+ hours in the ratio of about 20+ hours of coking and 2 or 3 hours of decoking.
What is the difference between coking coal and caking coal?
Coking coal is a type of coal that is used in the process of creating coke, a fuel used in steelmaking. It has a high carbon content and low impurities, making it ideal for this purpose. Caking coal, on the other hand, is a type of coal that softens and forms a solid residue when heated. This property is known as caking, and it is desirable for certain industrial processes such as coal gasification.
What is the difference between Hard coking coal vs soft coking coal?
Hard coking coal has higher carbon content and produces stronger coke upon heating, making it ideal for steel production. Soft coking coal has lower carbon content and produces weaker coke, often used in energy production or blending to achieve desired coke quality.
Coking coal Where found in India?
Bihar
Best coking coal is mostly obtained from?
jharia
What is refine oil?
Oil refining is the process of distilling oil and then further reforming, catalytic cracking, hydrofining, blending, and sometimes coking, hydrocracking, alkylating various fractions of the distilled oil.
Which raw materials are used by Port Talbot steel works?
Port Talbot steel works primarily uses iron ore, coking coal, and limestone as its main raw materials. Iron ore is processed to extract iron, while coking coal is utilized to produce coke, which is essential for the smelting process. Limestone serves as a flux to remove impurities during steel production. These materials are integral to the integrated steelmaking process employed at the facility.
