Dec 20, 1994 A return line is disposed between the cleaner and the pressure vessel for channeling the cleaned water thereto in a first mode of operation. A portion of the cooled water is bypassed around the cleaner during a second mode of operation and returned through.Research on coke making seeks to take advantage of insights that may help to reduce the proportion of prime coking coals utilised in coke blends and to expand the range of coals that could be used in these operations (Sasaki et al. 1998). Shifting the coke blend composition toward weakly coking coals is therefore commercially attractive.
Apr 01, 2019 In general, the coke with lower CRI and high CSR has a better quality, and the metallurgical coke with high quality is beneficial for the BF operation. However, the quality of coke used in BFs is deteriorating due to the lack of high-quality coal resources, making it important to study the effect of the quality of coke on the performance of BF.Oil and coke . The coking cycle can be as short as 10 hours in a fuel-grade coker operation, which is built to maximize throughput, or than 24 hours for higher-value commercial coke products . A lower coke drum operating pressure and less recycle will result in liquid and less coke produced . A modern delayed coker that maximizes.

Jun 10, 2019 Quenching of coke after carbonization is an important step that influences its strength and reducibility in a blast furnace. During the wet coke quenching process, hot coke from 1200 C is brought down to a temperature of around 100–150 C by impingement with jets of water. It was observed that the liners of quenching car buckets would fail during service in 15 days to 1 month. Chemical.Crushing o Carbon content of the cast iron is kept saturated. metal temperature and the mode of operation i.e., whether it is batch-type or continuous-type operation. Therefore, the refractory material for ball is most important item for the coke-less cupola operation and all development work has been completed with abundantly avail-.
