Coke_(fuel)

Coke is a solid carbonaceous material derived from destructive distillation of lowash, lowsulphur bituminous coal.. The volatile constituents of the coal—including water, coalgas, and coaltar—are driven off by baking in an airless oven at temperatures as high as 2,000 degrees Celsius. This fuses together the fixed carbon and residual ash. Most coke in modern facilities is produced in ...

Method for drying coal and cooling coke (Patent) |

A threecycle process as disclosed for drying and preheating coking coal using the heat from cooled coke. Cooling gas is passed over hot coke to heat the cooling gas and cool the coke. The heated cooling gas is then passed through a waste heat boiler and then back to the hot coke in a coke cooling chamber. This completes the first closed cycle.

Most of the chemicals derived from coal come from byproducts produced during the coking process. Coal is used to make coke to make steel. Coke gas (also called foul gas) contains coke tars, ammonia, and light oils. Tars are recovered and used to make tar derivatives. Ammonia is recovered as an aqueous solution or as an ammonium sulfate salt.

What Is the Difference Between Coal and Coke Fuel?

What Is the Difference Between Coal and Coke Fuel?

Coke is a byproduct of bituminous coal. When coal undergoes a process known as destructive distillation, it converts to coke. This process entails heating the fuel at a high temperature with no oxygen. The impurities and flammables burn off when coal changes to coke, and the result is a dull, porous substance with high carbon content. Although ...

Generally, the coke ovens found in the Cumberland region were used to convert the bituminous coal mined in the local mountains into industrial coke, a relatively cleanburning fuel used in the smelting of iron ore. In a process known as "coking," coal was shoveled into beehiveshaped coke ovens insulated with a layer of dirt and then ignited.
