Abstract The co-combustion of waste ion exchange resin (WIER) and coal in a coal-fired incineration plant is an economical and feasible treatment method. The effects of the amount of WIER on the co-combustion and pollutant emission characteristics are investigated in a thermogravimetric infrared analyzer and tube furnace respectively. Results show that the weight loss rate of WIER combustion is significantly higher than that of coal within 400 °C, and the ignition temperature of the mixture improves with the increased addition of WIERs. The release of sulfur dioxide during the combustion of waste anionic exchange resin (WAER) and waste cationic exchange resin (WCER) mainly occurs at 320–440 °C. The highest concentration of HCl in the combustion of waste mixed exchange resin (WMER) is mainly released at approximately 350 °C. However, the addition of WIERs causes a sharp decrease in the emission of NOx. Moreover, the sulfur and chlorine in the WIERs are respectively released in gaseous forms of SO2 and HCl and do not exist in the fly ash as salt compounds.

三种废弃离子交换树脂与煤的混燃及污染物排放特征

摘要 燃煤焚烧厂废离子交换树脂（WIER）与煤混合燃烧是一种经济可行的处理方法。分别在热重红外分析仪和管式炉中研究了WIER用量对混燃和污染物排放特性的影响。结果表明，WIER燃烧的失重率在400℃内明显高于煤，并且随着WIER添加量的增加，混合料的着火温度提高。废阴离子交换树脂（WAER）和废阳离子交换树脂（WCER）燃烧过程中二氧化硫的释放主要发生在320-440°C。废物混合交换树脂 (WMER) 燃烧中 HCl 的最高浓度主要在约 350 °C 时释放。然而，WIER 的加入导致 NOx 排放量急剧下降。此外，WIER 中的硫和氯分别以 SO2 和 HCl 的气态形式释放，而不以盐化合物的形式存在于飞灰中。
