摘　　要：酒钢焦化厂5号捣固焦炉应用了高辐射覆层技术,6号捣固焦炉没有应用。热工测试组对5、6号焦炉进行了各项热工参数和节能涂料全面有效的对比检测。结果表明:5号焦炉比6号焦炉传热效率提高6.35%,焦饼中心温度提高14℃,废气温度降低了23℃。每年可节约焦炉煤气420.48×104 m3,节能率为3.32%。炉窑统一热效率提高1.99%,炼焦耗热量降低了81.8kJ/kg(湿煤含质量分数7%的水)。每年CO2排放量减少132.5×104 m3,获得了较为明显的经济效益和社会效益。并提出了进一步降低炼焦耗热量的途径。The high radiative coating technology was used in the coke oven 5 in Jiuquan Steel Co.,The comparison test were conducted under different conditions in between the coke oven with and without coating.The results show that the heat transfer efficiency was increased 6.35% in coke oven 5,and the central temperature of coke cake increases 14 ℃,the flue gas temperature decreases 23 ℃ and saves coke oven gas 420.48×104 m3/a and the energy saving rate is 3.32%.The effective thermal efficiency of coke oven is increased 1.99%.The energy consumption for the coking process decreases 81.8 kJ/kg coal（with 7%H2O）,and CO2 emissions reduces 132.5×104 m3/a.Obvious economic and social benefits can be obtained.
