How a Coke Plant Works. 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 byproducts that come from that. So, there is an intermediate process that occurs. Coal is converted into coke first.

The integration of a postcombustion CO capture unit in a coalfired steam power plant leads to a reduction in net power output, where the largest contributors to the power loss are the heat requirement for the regeneration of the chemical solvent in the desorber of the CO capture unit (approx. 2/3) and the auxiliary power demand of the CO ...

Recovery and treatment of methane from coal mine ventilation air methane (VAM) with costeffective technologies have been an ongoing challenge due to low methane concentrations. In this study, a type of coconut shellbased active carbon was employed to enrich VAM with a threebed vacuum pressure swing adsorption unit. A new vacuum exhaust step for the VPSA process was introduced. The results ...

Understanding Sinter and Sinter Plant Operations. Sintering is a process of agglomeration of fine mineral particles into a porous and lumpy mass by incipient fusion caused by heat produced by combustion of solid fuel within the mass itself. The sintering process is a pretreatment step in the production of iron, where fine particles of iron ...

Mining Feature: Coal Mine Explosion Prevention. There are two main types of coalmine explosions: methane and coal dust. Methane explosions occur when a buildup of methane gas contacts a heat source and there is not enough air to dilute the gas level below its explosion point. Likewise, fine particles of coal dust in the right concentration that ...

How coal is formed. Coal is formed when dead plant matter submerged in swamp environments is subjected to the geological forces of heat and pressure over hundreds of millions of years. Over time, the plant matter transforms from moist, lowcarbon peat, to coal, an energy and carbondense black or brownishblack sedimentary rock.

The blended coal mass is heated for 12 to 20 hours for metallurgical coke. Thermal energy from the walls of the coke chamber heats the coal mass by conduction from the sides to the middle of the coke chamber. During the coking process, the charge is in direct contact with the heated wall surfaces and develops into an aggregate "plastic zone".

Coal is an essential primary energy source in modern industry. An important pathway of coal utilization is to gasify coal into syngas, which is then used for downstream production of numerous chemicals such as methanol and liquid fuels. Despite its wide applications, conventional coal gasification still faces challenges such as the use of a costly air separation unit and limited syngas H2/CO ...
