This paper presents the melting temperature (MT) and energy consumption (EC) of model municipal solid waste incineration (MSWI) fly ash (FA) under the influence of calcium oxide (CaO), silicon dioxide (SiO₂), aluminium oxide (Al₂O₃) and boron oxide (B₂O₃) based on thermochemistry simulations. Nine different base-to-acid ratios (B/A) of raw FA have been explored. The results show that the effects of CaO, SiO₂ and Al₂O₃ vary for different B/A ranges. SiO₂ and Al₂O₃ play positive roles in decreasing the MT and EC of FA4–FA9 with high B/A (B/A: 2.61, 4.48, 6.43, 6.90, 8.32, 8.82). CaO plays a positive role in decreasing the MT and EC of FA1 and FA2 with low B/A (B/A: 0.22, 0.43). In FA3 (B/A: 1.22), the MT and EC of FA cannot be reduced by adding CaO, SiO₂ and Al₂O₃. The addition of B₂O₃ cannot only further reduce the MT of FA, but also reduce the EC. B₂O₃ and SiO₂ can work together to reduce the MT and EC when B/A is high (2.61–8.82), and SiO₂ and B₂O₃ can be introduced into the FA by adding waste glass and other boron containing waste to realize the coordinated disposal of waste.

本文介绍了在氧化钙 (CaO)、二氧化硅 (SiO ₂ )、氧化铝 (Al ₂ O ₃ ) 和氧化硼 (B ₂ O ₃ ) 基于热化学模拟。已经探索了原始 FA 的九种不同的碱酸比 (B/A)。结果表明，CaO、SiO ₂和Al ₂ O ₃对不同B/A范围的影响不同。SiO ₂和 Al ₂ O ₃在降低高 B/A 的 FA4-FA9 的 MT 和 EC 方面发挥积极作用（B/A：2.61、4.48、6.43、6.90、8.32、8.82）。CaO 在降低低 B/A 的 FA1 和 FA2 的 MT 和 EC 方面发挥积极作用（B/A：0.22、0.43）。在FA3（B/A：1.22）中，加入CaO、SiO ₂和Al ₂ O ₃不能降低FA的MT和EC 。B ₂ O ₃的加入不仅可以进一步降低FA的MT，还可以降低EC。B /A高（2.61-8.82）时，B ₂ O ₃和SiO ₂可以共同降低MT和EC，SiO ₂和B ₂ O ₃ 可通过添加废玻璃等含硼废弃物引入FA，实现废弃物的协同处置。
