Analysis of Coal Gas Resource Utilization and Energy Flow View Model in Iron and Steel Enterprises

During the production and operation of iron and steel enterprises, a large amount of very important by-product gas resources such as blast furnace gas, coke oven gas and Linz–Donawitz process gas are produced. In order to realize the efficient use value of gas resources, focus on two aspects of its comprehensive utilization and optimization methods. Firstly, according to the different characteristics of by-production gas in iron and steel enterprises at present, the optimal use way is analyzed to promote the conversion of by-production gas from the main fuel utilization (or even direct emission) to the moderate resource utilization, so as to realize the improvement of comprehensive utilization rate. Secondly, according to the characteristics of gas energy flow system, an energy flow view description model is established and the linear optimization model of gas energy flow density is given; then, the feasibility of the optimized method is verified by simulation with actual data of a steel plant.
