Analysis of Influencing Factors and Optimization Measures for Thermal Efficiency of Ethylene Cracking Furnace
In steam cracking unit,the thermal effi-ciency of cracking furnace is an important index to e-valuate the advanced status,running status and energy saving and consumption reduction level of cracking furnace.Taking the CBL furnace of a steam cracking unit with an annual output of 80×104 tons in a refining and chemical enterprise as an example,the main fac-tors affecting the thermal efficiency of the cracking fur-nace were comprehensively analyzed,and according to the analysis results,the optimization measures for the thermal efficiency of the cracking furnace were pro-posed from four aspects of equipment,materials,oper-ation and management,in order to achieve energy sav-ing and consumption reduction of the unit,and pro-vide reference for the thermal efficiency optimization,and safe and stable operation of the cracking furnace.
