COMBUSTION CONTROLLER FOR OIL BURNER

PURPOSE:To stabilize the combustion from the beginning of the combustion, in an oil burner wherein the flow rate of fuel and the supplying amount of air are changed simultaneously while keeping an air to fuel ratio in constant. CONSTITUTION:A fuel flow rate changing means 3, into which the signal of an amount of combustion setting means 1 is inputted, drives a fuel pump 2 to supply the fuel into a burner 7. On the other hand, the fuel flow rate changing means 3 outputs the signal thereof also to the ventilating amount changing means 5 of a fan 4, which changes the ventilating amount of combustion air, while the ventilating amount changing means 5 controls the fan 4 so as to supply the amount of air comforming with the amount of fuel oil for the burner 7. A ventilating amount correcting means 8, operated by the signal of a room temperature sensor 9, is connected to the ventilating amount changing means 5 to reduce the amount of air, supplied from the fan 4 to the burner 7, when a room temperature is low at the time such as the beginning of combustion.
