The main contents of the present paper include: 1、The mechanism of fouling accumulation and the effects of fouling and slagging on boiler performance are analyzed. The model of fouling increasing is developed on the basis of sediment rate and denudation rate. The fouling monitoring models for boiler furnace and convective sections based on heat balance, the ones for air heater based on converted pressure difference are given. The implement results show that these models can reveal the cleanliness of boiler heat transfer surface. 2、The disadvantages of the model for boiler furnace fouling and slagging monitoring based on heat balance are discussed, and the calculation of radiant heat flux is considered as the primary difficulty.

主要包括以下内容： 1、分析了锅炉受热面污染形成的机理，从灰污的沉积率和剥蚀率角度出发，推导了受热面灰污增长的基本模型，分析了灰污热阻随积灰时间和烟气流速变化的规律，并通过大量现场试验，得到了沉积常数与时间常数的取值范围； 2、针对炉膛、对流受热面和空气预热器等不同受热面的传热特性，分别建立了基于热平衡和折算压差的污染在线监测模型，经实践验证，其监测结果能够满足现场工程应用的精度要求； 3、分析了基于热平衡原理的辐射、半辐射污染监测模型的不足之处，指出了机理模型因对炉内辐射换热量计算不准确，导致对以辐射换热为主的炉膛和以半辐射半对流的屏式过热器监测效果不够理想。

When the pH value of the solution contained in Cd~(2+) is near 5, the amount of Cd~(2+) exchange in analcime reaches to a summit; when the temperature increases, the amount of Cd~(2+) exchange in unit mass analcime also increases; when initial Cd~(2+) concentration decreases, the remove rate of Cd~(2+) increases while the amount of Cd~(2+) exchange in unit mass analcime also decreases; when other cations coexist in solution, there must be some influences to the Cd~(2+) exchange in analcime.

实验表明：当交换液的pH值为5左右时，方沸石对Cd~(2+)交换量较大：反应温度升高时，单位质量方沸石对Cd~(2+)交换量增大；随着溶液中Cd~(2+)初始浓度减小，方沸石对Cd~(2+)的去除率升高，但单位质量方沸石对Cd~(2+)的交换量逐渐减小；当溶液中有其他阳离子共存时，对方沸石与Cd~(2+)的交换也有一定的影响。
