摘要： A method for controlling combustion in a burner (1) includes the steps of setting one of the first (8) and second (9) regulating means to a first setting value (n'); calculating, as a function of this first setting value, the optimal pressure difference (ΔΡ') between the first (4) and the second (5) conduit, corresponding to a desired ratio between the air flow and gas flow that is considered optimal for combustion; detecting the real pressure difference by means of the differential pressure meter(ll), and regulating the other of the first and second regulating means so as to obtain a real pressure difference which is substantially equal to the optimal pressure difference. At predetermined time intervals, a step of automatic measurement of a percentage of obstruction of the flue (10) is carried out, in such a way that the optimal pressure difference is calculated taking into account for the variation with time of the resistance of the flue to the flow of spent gases.
