摘　　要：加热炉燃料能耗在原油管输总能耗中占比较大,节能涂料在不改变加热炉设备结构型式的状况下可以增强炉管黑度和炉壁反射率,提高加热炉热效率,从而广泛应用于各类加热炉。高辐射系数薄膜陶瓷涂料应用试验采用正、反平衡的热工测试方法,在涂料喷涂前后分别对加热炉进行了45%、75%两个负荷热工性能测试。结果表明:加热炉节能率在两种负荷工况下分别达到4.59%、5.72%,节能效果优异。高辐射系数薄膜陶策涂料能够提高加热炉热效率,降低加热炉单位能耗,经济效益显著,适宜推广应用。The fuel energy consumption of heater accounts for a large proportion of the total energy consumption of crude oil pipeline transportation.Energy-saving coating can increase the tube blackness and wall reflectivity of the heater without changing its structure,and then improve its thermal efficiency.Thus,it can be widely used in various heaters.In the application test of thin-film ceramic coating with high emissivity,thermal test with positive and negative balance was adopted.The thermal test was conducted to the heater at 45%and 75%load before and after coating respectively,and the results indicate that the energy-saving efficiency of heater under the two load conditions is excellent,reaching 4.59%and 5.72%respectively.Therefore,the thin film ceramic coating with high emissivity can improve the efficiency and reduce the unit energy consumption of the heater,and thus,it has significant economic benefits and is suitable for popularization and application.
