Performance Evaluation of Thermo Chemical Behavior of PCI Under Optimal Conditions
In this study, a three-dimensional mathematical model is used to simulate the flow and thermo chemical behavior of the enhanced operation of PCI Victorian lignite under optimal FC conditions. The geometry of the model includes a lance, a blowtorch, a nozzle, a track and a coke bed at the bottom of a BF. Under the same operating conditions, the highest temperature in the main coal pavilion is observed in the brindled lignite container due to its higher volatile matter content. Injecting lignite into briquettes can achieve a higher overall combustion value than the semi-coke container and the carbon container in the ducting. The comparison confirms the possibility of replacing the replacement coal with PCI coal with an improved lignite, as it shows a very similar evolution of the combustion characteristics under the same operating conditions.
