The coke is pushed through a coke guide into a quenching car. The quenching car carries the coke to either a wet quenching tower or dry quenching plant where it is cooled. Coke crushing and sorting plant The quenched coke is taken by conveyor to a crushing and screening plant also called coke crushing and sorting plant. Here the coke is crushed ...
The minimum coke rate is determined by requirements on gas permeability in dry shaft and in the cohesive zone, drainage of liquid products in the dripping zone, and renewal of deadman. ... The degree of crushing after the drum test is generally taken to be the index for coke strength. Based on different test standards, four room temperature ...
The graphitization of coke starts from the surface of coke and leads to the formation of coke fines, and the graphitization degree of − 74 μm coke fines is the highest. The temperature has an effect on the reaction rate of coke solution loss, and the higher the temperature is, the faster the reaction rate is.
Specific quality indices are essential to mitigate coke degradation and ensure optimal BF performance. From the lumpy zone to the hearth, coke should possess strong …
The wall temperatures of the coke oven are ramped at a set rate. 6. Once the centre of the charge reaches the target temperature, the ... • Selective crushing of blend components • Coal moisture content • Variation of bulk density (box charge required) • Stamp charging (box charge required) ...
At a lower coke rate, high-quality coke is essential for maintaining the bed permeability as there will be less amount of coke in the burden. The produced desired coke quality depends on two main variables: coal blend composition and process condition of the coke oven. Either of these variables will affect the quality of the
Material Crushing Equipments The crushing equipments are manufactured as per custom design. Manufacturing range of crushing includes, Jaw Crusher COMET Jaw crushers do the heavy work of breaking large pieces of solid material into small lumps. It is widely used in industry for coarse reduction of large quantities of solids. They operate by compression and break large lumps of …

Metallurgical coke is a prime burden support raw material, which contributes ∼60% of the hot metal production cost through the blast furnace route. It forms a packed bed in the …
The procedure for pilot scale coke-making from a gravity fed coal is: The coal is crushed to 80-85 percent passing a set size. The moisture of the coal is adjusted to target. The coal is gravity …
The results show that the heating rate affected the comprehensive combustion index and combustion reaction temperature range of the cokes. The ignition temperature, …
coke ovens must be crushed, usually to a top size of about 314-inch. Very small sizes must be screened from the crushed coke, leaving an acceptable size of about 3/4" ~1/8". Problems encountered in crushing chemical coke to the desired size range include excessive wear on …
After the crushing process, the cokes were screened again for the CRI/CSR test. Within experimental studies, 5 different by-products were added at 1 % to 5 different coal blends, and coking tests were carried out. ... the use of reactive coke in the blast furnace process is expected to improve efficiency and reduce the rate of coke acting as a ...
The pore structure of coke under CO2 atmosphere was investigated by the carbon solution-loss reaction experiment. The results show that the pore size distribution of coke gradually changes from dispersion to relative concentration with the increase in carbon loss rate, but it tends to be dispersed again in the late stage of the reaction, and the pore volume and …
On crushing the aggregated spheres their boundary surfaces are clearly seen ['2]. For continuous coking processes the basic features in coke formation, which are attributed to coking in un- ... Dynamics for the evolution of volat/les from coke from delayed coking (rate of heating 4 deg/min): 1) Eth- ane + ethylene; 9.) methane; 3) hydrogen; 4 ...

Fig 1 Typical flow diagram of a byproduct coke oven plant Environmental issues The coke oven is a major source of fugitive air emissions.The coking process emits particulate matter (PM), volatile organic …
The coke crushing strength is shown in Fig. 3. The crushing strength of coke is 2.61 MPa when coal is coked without pressing. If the blending ratio of bamboo, wood and straw is 5%, the crushing strength of hot-pressed cokes is 2.99 MPa, 3.11 MPa and 2.93 MPa, which is 1.15, 1.19 and 1.12 times compared with coke's strength in case of no ...
Table 8, comprising the results of these tests, shows that besides the Gryznov index of all bio-coke samples being higher (72-78, approx) than the prescribed value, the Shatter index from 78 to 84 ...
Impact crushers are another popular choice for crushing petroleum coke. They use a high-speed rotor and anvils to achieve size reduction. Impact crushers are more versatile than jaw crushers and can handle a wider range of materials, including materials with high moisture content. However, they require more maintenance and are generally more ...
In particular, the rate of coke descent at individual points within the horizontal plane is very different. The maximum speed measured at the height of the transverse channels differs from the mean by 25% [2]. In the chambers, the coke is segregated on charging: small pieces accumulate at the center, while large
The heater charge pump is equipped with a coke crushing impeller. Coke drum overhead vapor flows to the coker fractionator and enters below the shed section. The sheds serve to distribute the vapor and as de-entrainment trays for coke and tar particles that could be entrained with the coke drum overhead vapor.
Coke crushing tests were made on twenty-five pound samples. The 3" X2" and 2" Xl" sizes were tested separately on all cokes from the pilot oven. Commer- cial cokes were tested on the 3" x 1" size. Duplicate tests were made on all sam- ples where sufficient coke of the proper size was available. Duplicates are aver-
