Abstract

This paper aims to reveal the effect of adding biomass ash on the flow characteristics of Zhundong (ZD) coal ash. A new visual image measurement method for the flowability of coal ash was established. Furthermore, scanning electron microscopy (SEM) and x‐ray diffraction (XRD) were applied to analyze the influence of surface morphology and mineral component on the fusion fluidity of the samples. The results show that the flow properties of ZD ash are improved to varying degrees after adding maize straw (MS) ash. As the blending ratio increases, the improvement of flow velocity is higher. The critical flow temperature (TC) of the samples was calculated. The TC of ZD ash was 1249°C, which decreased with the addition of MS ash. The characterization results showed that adding MS ash increased the melting phase, while the surface of the samples tended to be dense and smooth. Meanwhile, the massive formation of hauyne with a low melting point and the high proportion of SiO2/Al2O3 in the ash promotes the melting behavior of the ash slag. The flow velocity of the samples is improved under the combined action of the increase of the melting phase and the smooth surface. [ABSTRACT FROM AUTHOR]

27. Industrial waste and biomass charcoal composite fuel for iron ore sintering: harmless disposal of waste and carbon reduction

Author

Abstract

The use of biomass fuel is an effective means to reduce the sintering process of iron ore. However, due to its high porosity and high reactivity, biomass fuel burns too quickly and has low combustion efficiency, resulting in insufficient heating during sintering and deteriorating quality. Using powder materials for pore filling and coating on the surface of charcoal is expected to reduce its reactivity and increase its usable ratio. This study used two types of industrial waste, carbide slag (CS) and white mud (WM), to modify charcoal by slurry impregnation and prepared several composite fuels for sintering experiments. The experimental results show that adding charcoal, which accounts for 20% of the total amount, to CS slurry with a moisture content of 55% or WM slurry with a moisture content of 45% can reduce the surface area of the fuel by 6.5 and 19.6% and reduce the average pore diameter by 48.0 and 56.3%, respectively. The ignition temperature of the composite fuels prepared by CS and WM increased from 378.6 °C of charcoal to 445.4 and 451.2 °C, respectively. Using composite fuels can increase the reduction rate of coke from 20 to 40%, providing a new way for CO2reduction in the iron ore sintering process and resource utilization of industrial waste.
