Abstract: Using gas to generate electricity is an important measure for iron and steel enterprises to optimize industrial structure and realize energy conservation and emission reduction.At the same time,gas power generation is also one of the important measures for the iron and steel industry to achieve the national carbon peak and carbon neutral development goals.Based on the discussion and analysis of the general layout characteristics of gas power generation projects in many iron and steel enterprises,this paper puts forward targeted treatment opinions for the key and difficult problems encountered,and puts forward reasonable layout scheme,so as to make the general layout of such projects scientific and reasonable.
