<p>A method and an apparatus for the setting of the working point of a burner, where a flue gas detector (11) together with an electronic control unit (13) determines the working point of the burner in an area with low CO concentration in the flue gas. An optimum determination of the working point of the burner shall be performed regardless of varying burner parameters, and the working point shall be maintained regardless of changes in the operating condition of the burner. This is achieved by first recording a characteristic of the burner in a memory circuit (6). Then the electronic control unit (13) performs a calculation of the characteristic contained in the memory circuit (6), and the working point is determined where a delta value for CO generation corresponds to a determined delta value. The burner is regulated to the working point found, and during continued operation the CO value of the working point is maintained until on the basis of a change of operating conditions or on the basis of operating period or number of burner starts, the electronic control unit (13) performs a new determination of the working point.</p> |
