摘要
输热管道运行一段时间后,内壁面会积起一层污垢,利用红外测温技术获得长圆筒形热设备外表面的温度分布,即可计算出内壁污垢层的厚度分布,从而为此类热设备运行状态的实时监测提供理论依据。
The thickness of internal dirt can be given based on the outer surface temperature distribution obtained by scanning for the hollow cylinder-shaped heat equipment. So the theoretical basis for testing intemal condition of heat equipment is given.
