日前,中国石化重大节能推广技术——扬子石化公司(简称扬子石化)乙烯装置裂解炉空气预热器全面投用,据估算,该项节能措施每年可节约燃料气超过5kt,有效实现了乙烯装置废热的回收利用,实现了节能减排,降本增效。原设计中,扬子石化乙烯装置裂解炉燃烧空气一直采用常温空气,不仅使炉膛燃烧温度得不到科学有效控制,增加了操作调节难度,而且浪费能源。为此,中国石化全面推广裂解炉空气预热器(简称空预器)节能技术,该技术
Recently, China Petrochemical major energy-saving technology to promote - Yangzi Petrochemical Company (hereinafter referred to Yangzi Petrochemical) ethylene plant cracking furnace air preheater fully operational, it is estimated that the energy-saving measures can save fuel gas more than 5kt per year, the effective realization of the ethylene plant Waste heat recovery and utilization, to achieve energy-saving emission reduction, cost reduction and efficiency. The original design, Yangzi Petrochemical ethylene plant cracking furnace combustion air has been used at room temperature air, not only the combustion temperature of the furnace can not be scientifically and effectively control, increasing the operational difficulty of adjustment, but also a waste of energy. To this end, China Petrochemical comprehensive promotion of pyrolysis furnace air preheater (referred to as air preheater) energy-saving technologies, the technology
