The article addresses the problem of regulating the thermal power of gas boilers under conditions of using fuels with unstable calorific value. Limitations of traditional automatic control schemes, oriented towards nominal regimes and stable fuel energy characteristics, are shown. A novel method of automated control is proposed, based on the dynamic formation of a mixture of certified and uncertified gases while maintaining a constant flue gas flow rate regardless of boiler load. The multilevel structure of the automated control system, its real-time operation algorithm, and principles of adaptation to fuel composition changes are described. It is demonstrated that the proposed approach ensures thermal power stability, increases boiler efficiency, and reduces specific emissions of combustion products.
