介绍了一种微纳米高温远红外节能涂料在原油管道加热炉的试应用情况,对不同测试条件下的测试结果进行了对比分析。结果表明:该节能涂料能明显降低加热炉的单位能耗,提高加热炉的热效率,但随着加热炉运行时间的延长,其节能效果逐年下降,使应用成本升高。为此,只有少数热负荷高、年耗油量大的加热炉使用该涂料才能产生经济收益。 A trial application of micro-nano high temperature far-infrared energy-saving coating in crude oil pipeline furnace was introduced. The test results under different test conditions were compared and analyzed. The results show that the energy-saving coating can significantly reduce the unit energy consumption of the heating furnace and improve the thermal efficiency of the heating furnace. However, with the extension of heating furnace operation time, the energy-saving effect declines year by year, which increases the application cost. For this reason, only a small number of high heat load, fuel consumption in large furnaces use the paint in order to produce economic benefits.
