Abstract

Automatic combustion control is a key factor in improving the efficiency, safety, and environmental sustainability of boiler installations. Deviations from optimal combustion parameters can lead to incomplete fuel combustion, increased emissions of harmful substances, or even emergency situations. Automatic control systems enable a stable and economical process by regulating the fuel and oxidizer supply in real time. One of the critical aspects of regulation is maintaining optimal draft pressure in the furnace, which ensures flame stability and promotes complete fuel combustion. This study examines the impact of draft pressure parameters on combustion efficiency, as well as methods for regulating draft using induced draft fans and forced draft fans. The application of modern controllers, particularly PID controllers, allows for rapid adaptation to changes in thermal load while maintaining the necessary balance between air supply and flue gas removal. The results confirm the effectiveness of the proposed automatic draft control system, achieving a 15% overshoot and a regulation time of 5 seconds. Promising areas for further development include the use of machine learning algorithms to predict combustion process changes and the enhancement of control systems based on flue gas composition analysis.
