The ethylene cracking furnace serves as a core thermal-processing unit in petrochemical production, primarily utilized to subject feedstocks—such as naphtha, light hydrocarbons, and ethane—to thermal cracking reactions within a high-temperature environment, thereby yielding fundamental chemical raw materials like ethylene and propylene. As the central component of large-scale integrated facilities, it directly dictates the yield of downstream products as well as the overall energy efficiency of the entire plant. By employing precise thermal field control and advanced tube material technologies, high-performance cracking furnaces are able to effectively suppress carbon deposition and coking—significantly extending continuous operating cycles—while simultaneously ensuring high conversion rates. The intricate design of their radiant and convective sections embodies the modern heavy industry's relentless pursuit of ultimate heat exchange efficiency and process control.
