摘　　要：针对导热油在供热系统中循环时,由于温度高始终伴随热裂解和热聚合反应,产生高分子黏稠物,最后形成沉渣、结焦,使仪表受损的缺陷,通常在循环泵的进口,一般应设置滤网目数合适的过滤器。在选择导热油热量计量仪表时应杜绝导热油外泄;在管路连接中尽量采用焊接,用波纹管密封代替填料函。不同牌号的导热油,密度、焓和黏度差异较大,在用焓差法计算热流量时,所用导热油的相关参数应准确。Due to pyrolysis and thermal polymerization associated with high temperature during HTF cycling in heat supply system, polymer dope will be generated with forming sediment and coke. It could damage instrument. The filter with proper mesh size is installed at inlet of circulation pump. The HTF leakage should be put an end during selection of heat metering instrument. Welding should be used for pipeline connection. Bellow seal should be used insteading of stuffing box. There are great differences among different grades of HTF in density, enthalpy and viscosity. Relative parameters of HTF should be accurate when enthalpy difference method is utilized to calculate heat flow.
