Analysis of energy consumption and energy saving ways in coke-making process of iron and steel production
With the growing of energy save work,the energy conservation of iron and steel industry is more and more difficultly.As the energy conversion unit,coke-making process is an important link in the process of iron and steel production.Therefore,the comprehensive analysis of influencing factors and deep exploration of energy saving limit of coking process are of great significance to the energy saving and emission reduction work of iron and steel indus-try.Taking the coking process as research object,based on the analysis method of input-output and heat balance,the influence of energy conversion difference and coking heat on energy consumption was comprehensively analyzed.Based on the heat balance,the coking heat was further divided into four factors,coal volatiles,moisture,coke oven heat loss and gas consumption ratio,and the influence of these factors on coking process energy consumption was discussed.In addition,based on the reaction mechanism of coke-making process,the corresponding production process was assumed by thermodynamic method,and the theoretical limit energy consumption of coke-making process was calculated based on the actual raw materials,fuel parameters and reaction conditions,which provided a theoretical basis for accurately judging the energy saving limit of coke-making process.Combined with the energy consumption characteristics of the current coke-making process,the application status of technology and the imple-mentation path of extreme energy efficiency work,the energy saving ways and energy saving potential of coke-mak-ing process were analyzed.Finally,by exploring the influencing factors of energy consumption in coking process and analyzing the theoretical limit energy consumption of coke-making process,it aims to provide theoretical basis for the ultimate energy efficiency of iron and steel production process and help iron and steel industry achieve the goal of reaching"carbon peak"and"carbon neutrality".
