Modern power generation increasingly faces the necessity of using hydrocarbon fuels of variable composition, in particular, artificial gases characterized by high variability in calorific value and combustible component concentrations. This instability of the fuel mixture significantly complicates the operation of traditional automated control systems for steam boilers, as most algorithms were designed for fuels with stable characteristics. The article analyzes modern principles for constructing combustion process monitoring and control systems for boilers of various purposes, examines the patterns of changes in the composition of natural and artificial combustible gases, and evaluates the suitability of existing approaches for operation under conditions of random fluctuations in the fuel's calorific value.
