WebTwo indices, coke reactivity index (CRI) and coke strength after reaction (CSR), are determined using the reacted coke residue. The weight loss after reaction determines the CRI. The weight retained after sieving the tumbled reacted coke in a designated number of revolutions over a designated turning rate determines the CSR. 4. WebFeb 15, 2024 · Predicted CRI pred and CSR pred coke indexes (type II) obtained by two-step procedure were then used for the set of 36 coal blends/cokes (type II) and provided very reliable results for both models 1 and 2. The correlation coefficints R between predicted and experimentally determined CRI and CSR were calculated for model 1 (R = 0.815 for CRI ...

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 … WebMar 5, 2010 · Using the Physical Properties of Coal Ash in Preliminary Assessment of the CRI and CSR Values of the Coke Produced, Koks Khim., 2008, no. 11, pp. 29–33.

In the test, a 200 g sample of –21 mm to +19 mm particle range coke is heated at 1100 °C under 1 atmosphere pressure of carbon dioxide for 2 hours. The coke is preheated and cooled under nitrogen and the weight loss during reaction is measured. The percentage weight loss is known as the reactivity (CRI). The reacted coke is placed in an I-type drum (no lifters) and subjected to 600 revolutions in 30 minutes. The percent of carbon material removed from the drum that is +10 m… WebCoke Testing Systems Coke Reactivity index (CRI) and Coke Strength After Reaction (CSR) High-temperature furnace Floor stand Inconel reaction vessel controls atmosphere Control cabinet includes SCR power supply, programmable temperature controller, over-temperature controller, N2 and CO2 monitoring and flow control system WebRequest PDF On Jul 15, 2024, Apsara Jayasekara and others published Microalgae blending for sustainable metallurgical coke production – Impacts on coking behaviour and coke quality Find ... birch run outlet hours
