Abstract
Servo gas system (11) for a gas burner (10), namely for controlling a pressure regulation valve (20) positioned in a gas duct (18) of the gas burner, thereby controlling a gas pressure within the gas duct (18) being present downstream of the pressure regulation valve (20) and thereby controlling a pressure difference between a pressure in a burner chamber (12) of the gas burner and said gas pressure within the gas duct (18), the servo gas system (11) comprising a static servo gas flow branch (28) and a dynamic servo gas flow branch (29) being connected in parallel, and a flow sensing element (30) being connected between the static servo gas flow branch (28) and the dynamic servo gas flow branch (29) and providing a signal used to control the pressure regulation valve (20) by an electric actuator (41).
