Gas burner for heating and/or hot water boiler incorporates flame temperature sensor for feedback regulation of air/fuel ratio and/or volumetric flow

摘要

The gas burner (1) has a device (3) for providing a combustible fuel/air mixture with a variable fuel/air ratio and volumetric flow, supplied to a burner (2) provided with a temperature sensor (12) positioned in the main reaction zone of the flame (17). The signal from the temperature sensor is fed to a control device (11) incorporated in the device for providing the fuel/air mixture, for adjusting the fuel/air ratio and/or the volumetric flow in dependence on the detected flame temperature. An Independent claim for a regulation method for a gas burner for a gas-fired boiler is also included.
