WebJan 11, 2024 · Research shows that the coke reaction rate at the coke weight loss of 25% (CRR25) and coke strength after reaction (CSR25) can explain the stable operation of a blast furnace. Lyalyuk [ 18] indicated that the CRI should be determined under specific operating conditions in blast furnaces. WebNov 16, 2016 · Coke strength after reaction (CSR) was predicted using linear regression of the CSR and CRI data. The estimated CSR was in good agreement with the CSR data. The sensitivity analysis of coal properties to CRI was also performed using the developed kinetic model. The model was successfully applied for coal blending to predict CRI of the …

WebDec 8, 2024 · The coke yield, coke reactivity (CRI), and coke strength after reaction (CSR) were measured. As shown in Table 1, the addition of 0.7% GL can effectively reduce the CRI and increase the CSR of the coke. The experimental results prove the effective role of GL in CRI reduction in the subsequent industrial coking experiments.
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 … WebThe CRI CSR Test System is an automatic equipment for determination of the Coke Reactivity Index (CRI) and Coke Strength after Reaction (CSR). This test device is fully …
WebThis test has two components; the Coke Reactivity Index (CRI) and the Coke Strength after Reaction (CSR). A coal which, when coked, achieves a low CRI value and a high CSR value is highly regarded in the market, primarily because this test has been related to blast furnace performance, particularly fuel rate and permeability of the burden.
