摘要
在国家规定的热网管道的每米热损失下,其保温层厚度随着保温材料的导热系数及工质温度的不同而不同。利用导出的计算公式,通过计算,将以上四个参数的关系用图表的形式表示出来,以供在热网管道的保温中予以应用。
According to heat loss of thennal network pipes per meter stated by nation, thickness of thermal insulating layer varying with theirnal conductivity of insulating material and temperature of working pair is studied by numerical calculation. The resuhs are presented with tables and figures to use conveniently.
