2004; Kuyumcu and Sander, 2014). The stamp charged coke ovens (Fig.1) differ little from the conventional top charged ovens, but the battery equipment is clearly different. The coking blend is compacted in a metal box with dimensions that are slightly smaller than the coke oven (20 to 30 mm). The stamping process is

It was also concluded that yield of coal tar and coke oven gas are more in top charging as compare to stamp charging. NH 3 yield is found more for top charging as compare to stamp charging,...
Considering the coking time, the actual productivity of stamp charging coke oven is about 10% more than that of top charging coke oven. 2. With the same quality, 20-30% weak coking coal, or high V.M gaseous or fat coal can be used to make coke. 3. This technology allows to widen the selection of coking coal and to reduce the unit cost of coking ...
2 "JUMBO OVEN" TOP CHARGED TECHNOLOGY. 2.1 "JUMBO OVEN" CONCEPT . 7.6 m tall "jumbo oven" battery represents worldwide the state of the art and consolidated technology for coke making plants. Here below is reported a comparison table between a reference project considering conventional 6.25 m vs. 7.6 m tall "large chamber" oven ...
Test for top-charge and stamp-charge coke oven batteries by 40kg test coke oven is described in this paper, which shows that the stamp-charge process can obviously improve the cold strength, crushing strength, abrasion strength and CSR of coke but it would uniformize the grain size composition since it has little effect on the CRI.
31-12-1994· The stampig method of coking was developed in Germany. It differs from the top-charging method only in the way the coke ovens are charged. A stamping machine compacts the coal charge which is then introduced into the coke chamber from the machine side.
CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): Abstract: The density of the coal charge plays an important role in the coke quality. The increase of the bulk density usually improves the coke strength due to increased coal particle contact and increased coke density. There are a few possibilities to increase the coal charge bulk density: adjusting the grain size ...
Cost effective: Stamp Charged Coke is about 35 % cheaper than Top Charged Coke Improvement of yield of Blast Furnace Sized Coke Improvement of Blast Furnace Productivity
Abstract: Test for top-charge and stamp-charge coke oven batteries by 40kg test coke oven is described in this paper, which shows that the stamp-charge process can obviously improve the cold strength, crushing strength, abrasion strength and CSR of coke but it would uniformize the grain size composition since it has little effect on the CRI.

Coke is an integral component of the blast furnace charge; therefore, it plays an important role in the integrated steelmaking process. Achieving the required coke quality parameters by producers requires the use of a high proportion of the highest quality coking coals (hard coking coals) in the coking blends, which significantly increases the unit production costs. Approximately 75% of these ...
14-12-2020· During the stamp charging process, the coal is stamped outside the coke oven, into a single „briquette" (coal cake), having almost the same dimensions as the oven chamber. This coal cake reaches a density of up to 1.15 t/m³ (on wet coal basis with 10% water) about 30% more than with the loose coal-charge during conventional top. More
