dc.description.abstractThis research focuses on reducing harmful emissions during hot blast stove (HBS) operation by enhancing the automated control system for checkerwork heating. The primary sources of emissions, including nitrogen oxides (NOx), sulfur oxides (SOx), and carbon oxides (CO, CO2), generated during the combustion of blast furnace gas, are analyzed. The authors propose improving the automated control system by implementing feedback on fuel combustion quality, continuous monitoring of exhaust gas composition, and real-time assessment of the fuel’s calorific value. The system’s structure includes regulating combustion airflow, continuous monitoring of blast furnace gas calorific value, evaluating combustion efficiency through O2, CO, and CO2 content analysis in exhaust gases, and adjusting the combustion process according to the mode map, maintaining the dome temperature within 1,350–1,420°C to minimize NOx formation. These measures contribute to reducing NOx emissions, enhancing energy efficiency, and stabilizing the temperature regime. The proposed solutions offer a cost-effective approach to emission reduction and can be seamlessly integrated into existing metallurgical enterprise systems.
