The main function of Coke Ovens is to convert coal into coke which is used as a fuel and reducing agent in the Blast Furnace. Its secondary function is to recover Volatile Matter and CO (Coke Oven) gas from coal and extract chemicals known as Coal Chemicals. CO gas produced is used for heating purposes in the plant. Heat from hot coke is

Fossil fuel combustion should be decreased in future years in order to lower the CO 2 emissions of energy production. The reduction can be achieved by increasing the amount of CO 2neutral fuels in energy 613% of coal was substituted with industrial or roasted pellets in a pulverized fuelfired power plant without making any changes to fuel grinding or lowNO x burners.

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 ...

Coal is a combustible black or brownishblack sedimentary rock, formed as rock strata called coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is a type of fossil fuel, formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.

Coke is made of a blend of typically three to seven coking coal grades. Coal grades have different properties: •. physical properties (density, grain size, petrography, ash, volatiles, moisture) •. chemical properties (P, S, K and Na contents, ash composition) •. coking properties (plasticity, shrinking, swelling) •.
