AI Technical Summary
The surge performance curve of the blast furnace blower changes with seasonal temperature variations. Existing technology cannot achieve dynamic adjustment, which leads to frequent venting of the anti-surge valve, resulting in energy waste and affecting the safe operation of the blast furnace.
By testing the surge performance of the wind turbine, a two-dimensional coordinate system is established, temperature compensation is performed, the surge line is corrected, and the anti-surge control is dynamically adjusted. The opening of the anti-surge valve is adjusted in real time using a variable gain model to ensure that the wind turbine operates close to the anti-surge line.
This achieved optimal performance of the blower, reduced energy consumption, stabilized the blast furnace air volume and pressure requirements, and ensured the smooth and safe operation of the blast furnace smelting process.
