WebMar 13, 2024 · 4.1 When coke lumps descend in the blast furnace, they are subjected to reaction with countercurrent CO 2 and to abrasion as they rub together and against the walls of the furnace. These concurrent processes physically weaken and chemically react with the coke lumps, producing an excess of fines that can decrease burden permeability and … WebJun 25, 2014 · For quantitative assessment of the coal’s mineral component, which has an important influence on the coke quality—specifically, on CSR and CRI —the potential reactivity of coke ( CRP) is recommended as a better characterization of the index B b. Three- and two-parameter versions of the formula for CRP are presented.
WebThe CRI is reported as the percent weight loss of the coke sample after reaction. The cooled, reacted coke is then tumbled in an I-drum for 600 revolutions at 20rpm. The cumulative percent of plus 10mm (3/8inch) coke after tumbling is denoted as the CSR. Generally, cokes with high CRI values have low CSR's and cokes with low CRI values have high
WebCoke Reactivity Index (CRI) and Coke Strength after Reaction (CSR) When coke descends in the blast furnace, it is subjected to reaction with countercurrent CO 2 and abrasion.
