Abstract: This paper introduces the main problems existing in the domestic low pressure steam system of large-scale iron and steel enterprises. Based on the analysis of the system structure of low pressure steam, the mathematical models of the different steam producers are developed and the optimal regulation model (improved simplex linear programming) is set up to get the optimal way. In addition, this paper takes one iron and steel enterprise as an example and does an empirical research on the result of the optimal model. Large energy-saving potential could be achieved by the optimal operational planning.

摘要： 介绍了国内大型钢铁企业低压蒸汽系统存在的主要问题，在分析低压蒸汽系统结构的基础上，针对大型蒸汽管网不同产汽源系统建立相应的数学模型，利用改进单纯型法求已建立的线性规划模型的最优解，并以某大型钢铁企业为例，证明了应用优化模型的有效性，通过蒸汽系统优化调度，钢铁企业具有巨大的节能潜力。
