Abstract
ABSTRACTThrough the research on the mechanism of iron ore sintering process, we used Fluent software to simulate the sintering process and establish a mathematical model of heat and mass transfer; moreover, we used the sintering cup experiment to verify the reliability of the model. The experimental results showed the following: when adding biomass fuel, the thickness of the material layer with the temperature higher than 1573 K decreased slightly; meanwhile, the thickness of the material layer with the temperature higher than 1723 K decreased drastically. Comparison of the emission content of SO2 in conventional sintering and sintering with biomass fuel showed that sintering with biomass fuel could reduce SO2 content in sintering flue gas. Considering sinter properties and SO2 emission reduction effect, sintering material that was added 30% biomass fuel to replace coke breeze could ensure the ore-forming process, and could realise the environment-friendly production.
