Esperimental Study Of Mixed And Active Desulfurizing Agents On CFBA

This paper selects calces ,coke breeze and sinter ash etc. as material which were mixed and experienced activation, in the end, getting a new desulfurizing agents on CFBA. Desulfurizing agent is calces,and additives agents are coke breeze and sinter ash.As far as desulfurizing agents are concerned,when they are mixed they are called mixture desulfurizing agents.There are three kinds agents: A ,B , C. The experimental results indicate that additive can increase the usage efficiency of CaO.Fe₂O₃ is the best desulfurizing agent.Agent B is better in the usage efficiency of CaO than agent A, 38% higher. So the experiment gives a expected result.The Active Desulfurizing Agent is made by hydration method . Through hydration , steam and hydration steam methods produce three Active Desulfurizing Agent — D,E and F. The study shows that high temperature is benefit to increase the usage efficiency of CaO. Agent F by steam activation perform more efficiency of using CaO than agent D,approximately 49%. Therefore, we can see perfect prospect.In the CFBA's rotten experiment, the study indicates that the erode velocity of metal is about 6. 51mg/dm² · d and the erode depth is 300μm/a.The experimental results provide reference to CFBA.
