Abstract
Gas purification in ferroalloy furnaces is vital for the efficiency and quality of the entire production process. To enhance the efficiency of the gas purification system, an upgrade to the bag filter regeneration control system has been proposed. Using the SimInTech dynamic modeling environment, the performance of the control system was evaluated before and after modernization. Key quality indicators and misalignment errors were calculated to assess the proposed engineering solution. The speed increased by 3.8 times, reducing response time to 2.9 s, the stability increased by 3 times, achieving a stability degree of 1.05, the reliability of the control system increased by 4.2%, reaching a reliability rate of 96.3%, and the misalignment error decreased by 30 s, resulting in a misalignment error of 25 s. Operational data from the Aktobe Ferroalloy Plant were used to assess the impact of the modernization on productivity, energy efficiency, and the overall quality of the gas purification system. The average efficiency coefficient of the regeneration system was determined to be 34.75%.
