摘要: 利用低温FAE烟气空气换热器的优势对S Zorb装置加热炉余热回收系统进行改造。改造后解决了原有余热回收系统热管式空气预热器的漏风、腐蚀、换热面积不足和引风机的潜在隐患等问题;同时,使加热炉燃料热效率由91.5%提高到94.3%,获得了可观的经济效益和社会效益。组合式FAE烟气空气换热器不仅能应用于旧炉改造,也可应用于新装置,为石化企业加热炉深度节能减排做出了一定贡献。

Abstract: The waste heat recovery system of heating furnace in S Zorb unit is reconstructed by making use of the advantages of ultra-low temperature FAE exchanger. The problems of air leakage, corrosion, insufficient heat transfer area and potential hidden troubles of induced draft fan in the heat pipe air preheater of the original waste heat recovery system were solved after the reconstruction. Meanwhile, thermal efficiency of the heating furnace was increased from 91.5% to 94.3%, and considerable economic and social benefits were obtained. The combined ultra-low temperature FAE exchanger can be used not only in the old furnace reconstruction, but also in new devices. It has made certain contribution to the deep energy saving and emission reduction of heating furnace in petrochemical enterprises.
