Abstract (en)
[origin: WO2011117896A1] A control method of a boiler provided with atmospheric burner comprises a valve for controlling the gas sent to a burner (14), means (10) for detecting the flame present in the latter and control means (13) of functional components of the boiler such as the gas valve (15), a fan, provided with its own electric motor, a circulator o pump, a temperature probe, said control means (13) co-operating with a memory (12) wherein a plurality of optimum operating conditions of the boiler is tabulated functions of features related to the flame, to the thermal power and to the value lambda. The working point of the boiler is determined on one of such curves, the ratio between combustion air and gas is modified starting from a current operating value, in order to shift such working point along such curve, it is verified if such variation of the ratio arrives at a predefined value and in that case a previous air-gas ratio of correct operation is reset, in the opposite case the gas flow rate being modified in order to obtain an optimum combustion ratio. Protection is also claimed for a device for accomplishing such method.
