Abstract (en)

[origin: EP0784190A1] A device (1) for optimizing the efficiency of a gas-fired heat generator comprising a burner positioned within a combustion chamber provided with a fan for evacuating burnt gases, the fuel reaching said burner via a feed pipe in which there is positioned an electrically powered pressure regulator, said regulator being controlled to vary the gas flow rate to the burner by electrical signals generated by a control unit of the heat generator. The device comprises fan command and control means (2) which measure the electrical control signals (VREF) of the pressure regulator, said signals (VREF) being compared with a reference signal (VR) to generate a control signal for the fan, the rotational speed of this latter being modified on the basis of the control signals (VREF) which reach the pressure regulator. <IMAGE>
