基于热辐射涂料存在散热损失大、易脱落、使用寿命短等缺点,研制了FR-1热反射涂料。该涂料的节能原理是:降低炉衬的黑度,减小对辐射热的吸收率,增大反射率,使炉衬具有重辐射面的性质,在传热过程中作为中介物,将烟气和火焰的辐射热完全返回到炉内。分别在中国石化广州分公司、高桥分公司、中国石油玉门油田分公司进行了FR-1热反射涂料的工业试用,并在中国石化襄樊输油处加热炉上进行实际应用,结果表明:辐射炉管背面吸热量可提高1.5%,辐射室外壁温度可降低10%～15%,散热损失可减少30%～50%,燃料节约率达2%,全炉热效率可提高1%以上,炉年均热效率提高1%以上。 Based on the existence of thermal radiation coating heat loss, easy to fall, short life and other shortcomings, developed FR-1 heat-reflective coating. The energy-saving principle of the coating is to reduce the blackness of the lining, reduce the absorption rate of the radiant heat, increase the reflectivity, and make the lining have the property of the heavy radiation surface. During the heat transfer process, the flue gas and the flame The radiant heat is completely returned to the furnace. The industrial trial of FR-1 heat-reflective coating was carried out in Guangzhou Branch of China Petrochemical Corporation, Gaoqiao Branch and Yumen Oilfield Branch of SINOPEC and the practical application was carried out on the heating furnace of Xiangfan Oilfield in SINOPEC. The results showed that: The heat absorption on the back of the radiant tube can be increased by 1.5%, the temperature of the outer wall of the radiating chamber can be reduced by 10% -15%, the heat loss can be reduced by 30% -50%, the fuel saving rate can reach 2% and the thermal efficiency of the furnace can be increased by 1% Furnace average annual thermal efficiency increased by 1%.
