HCl and SO emission is one of the major concerns related to municipal solid waste incinerator (MSWI). In this study, a material flow analysis model was developed to estimate the HCl and SO concentrations in the MSWI flue gases (FGs), and their concentrations in the full-scale MSWI were monitored. The calculated concentrations of HCl and SO in the FG were 770-1300 mg/Nm and 150-640 mg/Nm, respectively, in close agreement with the monitored values. More than 99% of Cl and 92% of S from the FG were captured into solid residues by the air pollution control (APC) systems. Moreover, since only 48.4%-67.5% of Cl and 21.3%-53.4% of S were transferred to the FG from the municipal solid waste (MSW), it was more reliable to estimate the source strengths and release amounts of HCl and SO in the FG based on the amounts of Cl and S in the APC residues (AR) and exhaust gas rather than in the MSW. This simple method is easily applicable and the estimated results could provide scientific basis for the appropriate design and operation of the APC systems as well as corrosion control of heat recovery systems.
HCl 和 SO 排放是与城市固体废物焚烧（MSWI）相关的主要问题之一。在这项研究中，开发了一种物料流分析模型来估算 MSWI 烟道气（FG）中的 HCl 和 SO 浓度，并监测其在全规模 MSWI 中的浓度。FG 中 HCl 和 SO 的计算浓度分别为 770-1300 mg/Nm 和 150-640 mg/Nm，与监测值非常吻合。超过 99%的 Cl 和 92%的 S 从 FG 被空气污染控制（APC）系统捕获到固体残留物中。此外，由于从城市固体废物（MSW）中仅有 48.4%-67.5%的 Cl 和 21.3%-53.4%的 S 转移到 FG 中，因此基于 APC 残留物（AR）和废气中的 Cl 和 S 量来估算 FG 中 HCl 和 SO 的源强度和释放量更为可靠，而不是在 MSW 中。这种简单的方法易于应用，估算结果可为 APC 系统的适当设计和运行以及热回收系统的腐蚀控制提供科学依据。
