Optimization of coal blends for coke making by the stamp

1994. 12. 31.  Stamp charging means coke production in horizontal chamber ovens, where the coal blend is previously compacted to a so-called coal cake with slightly smaller dimensions than those of the oven and charged to the oven from the battery ram side through the oven door.

Application of Binder in Stamp Charge Coke Making

Stamp charging has been established as a versatile tech-nology which not only improves the coke properties that can be obtained from a given coal blend, but also broadens the coal base for coke making, permitting the use of inferi-or coals without impairing the coke quality. But, when compared to the conventional top charging, stamp charging

Coal Stamp Charging Battery Industrial Efficiency

2017. 9. 13.  During the stamp charging process the coal is compacted outside the coke oven, into a stable "briquette“ (coal cake) with almost the same dimensions as the oven chamber and the resulting cake is pushed into the oven. With stamp charging the bulk density of the charge is increased between 30 to 35% (a 45% increase is reported in Veit D'Lama, 2002) and the productivity of the oven is ...

Stamped coal cakes in cokemaking : Part 2 –

Abstract Coking of coal blends using high volatile coals with poor caking properties to produce a high quality coke for blast furnace application can be achieved by compacting the whole coal blend before the pyrolysis in the so called stamp charge operation. Using stamp charging not only improves the flexibility of the cokemaking plant using cost efficient raw materials, but also increases ...

2014. 5. 26.  COALS FOR STAMP CHARGING As stamp charging can accommodate a wide range of coals, it is difficult to specify an individual coal of the blend.. In general, the vitrinite reflectance will be below 1.0 and the ash less than 10.0 %, if available. Volatile matter can be as high as 35 % in a particular coal (Australian ultra high volatile) but has to be balanced by the addition of low volatile coals ...
