Coal Anthracite Bituminous Coke Pictures Formation Uses

Coke production remains an important use of coal Coke is produced by heating coal under controlled conditions in the absence of air This drives off some of the volatile materials and concentrates the carbon content Coke is then used as a high-carbon fuel for metal processing and other uses where an especially hot-burning flame is needed...

Coal to Coke Conversion Process

The process in which conversion of coal to coke takes place is referred to as coal carbonization Coke is nothing but a carbonaceous material solid in nature which is again derived through the process of destructive distillation of low ash low-sulfur and bituminous coal The transformation of coal to coke is better known as the coke-making...

How does coke and coal play into steel making

Jun 22 2016 0183 32 Quality of coal In either coke or non-coked coal the quality of the coal affects the quality of the steel Metallurgical coke is made from bituminous coals by a distillation process Ash deposited by the coal must be kept to a minimum preferably below 10 of the original mass...

How a Coke Plant Works

Oct 04 2018 0183 32 Coal is the main ingredient used to make coke Iron is produced by inputting coal into a blast furnace However coal cannot be put directly into a blast furnace because of all the harmful by-products that come from that So there is an intermediate process that occurs Coal is converted into coke first Coke is used as fuel in a blast furnace...

Steel Production

Coal is a key part of the coke-making process The coal is crushed and ground into a powder and then charged into an oven where it is heated to approximately 1800 176 F in the absence of oxygen As the oven is heated the coal begins to melt so most of the volatile matter such as oil tar hydrogen nitrogen and sulfur are removed...

Making steel without coal Lets talk about coal

Specifically the coal was converted into coke by heating it in oxygen-starved conditions to drive off embodied water and volatile organic chemicals This produces a hard grey porous material composed mainly of carbon This has a much higher energy value than coal and is better geared to producing high temperatures for smelting...
