PURPOSE:To control an abrasion of burner tips effectively and economically by controlling the abrasion of burner tips with an amount of fuel flowed through burner tips. CONSTITUTION:In addition to a due regard to a fact that a flowing amount of the fuel to a burner is approximately proportional to a root of pressure P of the fuel which is supplied to the burner, it is confirmed that whether individual burner is used by a limit switch 4 provided to a burner valve 2. Then, an integrated value of the flow amount of the fuel of individual burner is determined by an integration of root of supplying pressure of the fuel about individual burner only while the valve 2 is opened, and thus obtained value is regarded as a grade of a progress of the abrasion. Further, more accurate grade of the progress of the abrasion is obtained by increasing a factor of proportionality of integral, every time when a specified value is exceeded by the integrated value of the flow amount. Thereby, the abrasion of burner tips may be controlled effectively and economically.
