High calcium in the municipal solid waste incineration (MSWI) fly ash made it a potential material for replacing part of the calcium flux used in iron ore sintering process. The results show that the sintering indexes were not negative affected but improved slightly as MSWI fly ash added, which is mainly because the ultra-fine material helped to obtain a better granulation and produced liquid phase under high temperature. Removal rates of harmful elements were improved as the increased content of chlorine brought in by the MSWI fly ash, which means that the residual contents of K, Na, Pb and Zn in the finished sinter were not increased significantly. 93.03% of the dioxins in the MSWI fly ash was degraded due to the fast heating rate and high temperature during sintering process, both of which are favorable factors for the degradation of dioxins. Although the addition of the MSWI fly ash made the concentration of SO₂ and dioxins in the flue gas increased, standardized discharge can still be realized through conventional activated carbon system for flue gas purification. Therefore, the resource utilization and harmless disposal of MSWI fly ash can be realized through iron ore sintering process.

城市固体垃圾焚烧（MSWI）粉煤灰中的高钙使其成为替代铁矿石烧结过程中使用的部分钙通量的潜在材料。结果表明，加入MSWI粉煤灰对烧结指数没有不利影响，但有轻微改善，这主要是因为超细材料有助于获得更好的造粒效果，并在高温下产生液相。随着MSWI粉煤灰中氯含量的增加，有害元素的去除率得到了提高，这意味着最终烧结矿中K，Na，Pb和Zn的残留量并未显着增加。MSWI粉煤灰中93.03％的二恶英由于烧结过程中的快速加热速率和高温而被降解，这两者都是导致二恶英降解的有利因素。₂，烟气中的二恶英增加，仍可通过常规的活性炭系统对烟气进行净化，实现标准化排放。因此，通过铁矿石烧结工艺可以实现MSWI粉煤灰的资源利用和无害化处理。
