Abstract:

Based on periodical change of generation, storage and consumption of byproduct gases, the features of supply-demand change of steam and electricity for each period, aimed at minimizing energy consumption and optimal benefit of cost-effective, a multi-period coupling model of surplus byproduct gas, steam and electricity in iron and steel works was formulated.The model is implemented by ILOG Cplex and the optimal distribution scheme of byproduct gases, MP steam, LP steam and electricity is obtained.The results indicate: the model can distribute the energy medium reasonably, safely and efficiently, such as surplus byproduct gases, steam and electricity, for improving energy utilization efficiency and decreasing the product cost.
