“…To visually reflect the flow properties of ash, some scholars investigated the high‐temperature flowability of ash slag based on the image method. Li et al 20 combined with AFT and mineral analysis and explored the effect of the synergistic effect between Na 2 O and K 2 O on ash melting behavior. Zhang et al 21 studied the effect of adding coal indirect liquefaction residue (LR) on the melting fluidity of coal ash through AFT and explained the melting mechanism of coal ash by using the change rate of ash cone height.…”

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 (T C ) of the samples was calculated. The T C of ZD ash was 1249 C, which decreased with the addition of MS ash. The characterization
