Most coke ovens, built before 2000, were topcharging type. After 2000, stampcharging became increasingly popular due to the following advantages: Use a wider coal resource base, like lean coal; even anthracite. Blend a larger amount of weak caking coal, at most 30—40%. Achieve lower operating cost: .
Moreover, the ash components have affinity for water and pure coal repels water, which in case of pure coal, works against the holding together of the blend. Hence, lower the ash content, less is the bulk density of cake under identical stamping energy and lower the bulk density, less is the oven throughput.
Classified in various types, the coke oven is a large furnace in which the coke, an indispensable raw material for iron making, is produced. Generally the lower portion of the furnace is a regenerator and the upper portion is partitioned vertically into many coking chambers and .

the process of converting coal into coke using the byproduct coke oven, the volatile matter in the coal is vaporized and driven off.

After leaving the coke oven chambers, the raw coke oven gas is cooled which results in a liquid condensate stream and a gas stream.
Coke is produced by heating coking coals up to 1000 to 1200 °C for several hours in coke ovens to drive off volatile compounds and moisture. For every ton of coke around to GJ of energy (IEA, 2007. ) and around ton of coking coal is used (IEA, 2009, ).

Ford River Rouge Plant Buildings. The first coke ovens were installed here in 1919, and presently 205 ovens are in operation. One hundred ninetytwo are the KoppersBecker type and 13 are the Wiloptte type. Each oven has a capacity, and together they are capable of processing 4,200 tons daily.
against the oven to receive coke. The pushing ram is extended inside the oven pushing the bed of coke into the FPHC. After the pushing ram has been extracted from the oven the charging side of the machine is linedup on the oven to start the charging operation. Prior to charging the coal, the coke side door is replaced and latched.
