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。

Preheating system of the die set of swaying tray is heated by adopting Cr20Ni80 resistance wire, as diameter d is 1.5mm, node-pitch D is 36mm, screw-pitch h is 4mm, spiral column L' is 0.91m, 220V single-phase contacting is adopted.

摇盘模具预热系统采用Cr20Ni80 镍铬合金材料电阻丝加热，直径d 为1.5mm，节经D 选用36mm，螺距h 选用4mm，螺旋柱长度L'为0.91m，采用220V 单相接法。

For the proposed project the waste gas emission locations include: preheating furnace of hard alloy parts line (when natural gas is used for heating while excess heat heating system goes wrong), melting furnace, refining furnace, heat treatment furnace for machining unit and steam boiler. The pollutants are SO2, NOx and smoke dust contained in the smoke generated from the above locations. All the above pollution generating facilities use the most clean energy, natural gas, for burning. Meanwhile, on melting furnace and refining furnace low nitrogen combustion technology such as low NOx burner is applied, and the generated smoke is discharged via chimney.

拟建项目之废气排放部位为硬质合金件生产线的预热炉（余热加热系统故障采用燃天然气加热时）、熔化炉和精炼炉及机加工机组热处理炉和蒸汽锅炉，污染物为以上部位产生的烟气中含有SO2、NOx以及烟尘，以上各产污设备均采用最清洁的能源——天然气为燃料，同时熔化炉和精炼炉采用低NOx烧嘴等低氮燃烧技术，产生的烟气由烟囱排放。
