摘　　要：高炉煤气、焦炉煤气和转炉煤气是钢铁企业生产过程中的副产品,作为燃料广泛应用于钢铁生产的生产工序中.在实际生产中,不同工序所需煤气的热值差别很大,采用单一煤气供应极易造成煤气过量放散,或者煤气供应不足而影响生产,因此必须对这三种煤气混合使用.即针对不同工序,在备选的煤气混合方案中选择其一,并根据生产需要确定具体的混合量.以煤气放散成本和煤气不足损失成本之和最小化为目标,同时兼顾煤气管网压力与流量平衡,建立了煤气混合优化分配的0-1混合整数规划模型,并考虑了不同煤气混合及能源分配的工艺要求.以某大型钢铁企业的实际生产数据为例,利用CPLEX软件求得了问题的最优解.The byproduct of iron and steel plant including blast furnace gas, coke oven gas and converter gas can be extensively used as fuel in almost all operations of iron and steel production. In practice, the gases required by various operations differ greatly in heat value, using a single type of gas will cause the diffusion of other gases, or affect the production because of the short supply of gas. Therefore, the three types of gases must be mixed to supply the production, that is, select one mixing scenario and determine the amount according to the production demand for each operation. This paper formulates a 0-1 mixed integer programming model for gas mixing and optimal distribution by using the minimum gas diffusion cost and short supply cost as the objective. The balance of gas pipe pressure and flow, the technological requirement of gas mixing and distribution, are considered. Based on the practical data of a large scale iron and steel plant, the model is solved to optimality by using CPLEX software.
