Abstract

This patent describes a combustion control method for gas combustion units with automatic pre-mixing of the air/gas mixture. Said control method implies calculating the estimated air excess value λ, by using at least two physical magnitudes of the combustion status (J, θ; J1, J2; θl, θ2) close to the flame point during standard operation in specific positions (p.l, p.2); wherein said magnitudes are ionization currents (J) and flame temperatures (θ). The method also includes, a) the processing of a mathematical method suited to evaluate the excess air value λ, b) the determination of the operating conditions at values λ that represent optimal, briefly tolerable and intolerable parameters, regardless of the values of the mathematical model, c) the regular recalibration of the mathematical model The patent also describes the means to implement said method.
