Eulerian-Lagrangian simulation study of the gas-solid ...
The coalChemistry is a standard solver suitable for dilute gas–solid reacting flow, in which the collision effect is neglected, and the gas-particle phases are solved in a two-way coupling manner. For the coal gasification in the BFBG, an integrated model for dense gas–solid reacting flow in a four-way coupling manner is needed.

the ovens in series. This unpurified "foul" gas contains water vapor, tar, light oils, solid particulate of coal dust, heavy hydrocarbons, and complex carbon compounds. The condensable materials are removed from the exhaust gas to obtain purified coke oven gas. As it leaves the coke chamber, coke oven coal gas is initially cleaned with a weak ...
How a Coke Plant Works - GASP
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 by-products that come from that. So, there is an intermediate process that occurs. Coal is converted into coke first.
