Regression Analysis of Blast Furnace Blower Surge Curve
HeSteel Group Handan Ironmaking Plant in the process of blast furnace installation and commissioning,due to the change of air temperature and atmospheric pressure,from time to time the equipment wheezing,the blower efficiency can not meet the pressure needed for the production of the blast furnace.Based on this,according to the change of temperature and the influence of air pressure,the output pressure of blast furnace blower and the root cause of wheezing were carefully analysed,and 5 groups of static lobe angles were selected to test the throat differential pressure and outlet pressure.After relevant regression analysis of the data,we determined the wheezing curve and anti-surge curve of the unit,and carried out re-calibration.After the commissioning operation,the effect is good.
