Description

technical field [0001] The invention belongs to the technical field of blast furnace energy saving and emission reduction control. In particular a blast furnace CO 2 Intelligent emission optimization control system. technical background [0002] Iron and steel enterprises are the industries that have the greatest impact on the control of greenhouse gas emissions, and their greenhouse gas emissions are mainly in the form of CO 2 emission-based. Among the carbon emissions of my country's iron and steel industry, more than 95% of the carbon emissions come from energy consumption. Use energy-saving and emission-reduction technologies to reduce CO 2 Emissions, the most feasible and effective emission reduction measure is to reduce process energy consumption. The blast furnace ironmaking process is the process with the highest energy consumption in the steel production process, and its energy consumption accounts for more than 50% of the total energy consumption. Therefore, t...
