Optimization of Gas-Steam-Electricity Network of Typical Iron and Steel Enterprise

Due to the fact that by-product gases constitute significant secondary energy sources in iron and steel enterprises, their reasonable distribution is critical for energy conservation and consumption reduction. In the current study, there is a lack of in-depth thinking about the impact on an entire system owing to the adjustment of single equipment in the process. In this paper, the model combined of gas distribution, steam, and electricity optimization is established based on the mechanism. By using a typical enterprise scene of adjusting the by-product gas combustion ratio of heating furnace, the impact of changes in surplus gas on the Gas-Steam-Electricity network is analyzed. When the ratio of coke-oven gas:blast furnace gas:basic oxygen furnace gas is 2:2:1, the lowest operating cost of the entire system is 95.511 CNY/t-cs, and thus, 5.2619 million CNY can be saved every year. Therefore, the rational allocation and use of by-product gas can bring considerable benefits to the whole enterprise. [GRAPHICS] .

Automated summary

This study analyzes the importance of reasonable distribution of by-product gases in iron and steel enterprises for energy conservation and consumption reduction. The research finds that the rational use of by-product gases can significantly reduce the operating costs of the entire system and bring considerable economic benefits.
