PURPOSE:To obtain heat energy at the maximum efficiency by a method wherein the system, controlling the ratio of a fuel supplying amount to an air supplying amount so as to make the intensity of the band spectrum of a light emitted from a combustion flame maximum, is provided. CONSTITUTION:The system consisting of the first and the second controllers 41, 42, controlling the ratio of the fuel supplying amount and the air supplying amount so as to make the intensity of the band spectrum of light emitted from the combustion flame maximum, is provided. When the fuel is petroleum, for example, and the flow amount of air of a control valve 36 in case the intensity of a desired wave length such as 429nm is attained the maximum value is larger than the half of the maximum flow amount thereof, the controller 42 outputs a signal to control valve 34 so that the flow amount of the air flowing through the control valve 34 is reduced by a predetermined amount, on the contrary, when it is smaller than the half of the maximum flow amount, a signal is outputted so as to increase the amount thereof. As a result, the ratio of the feeding amount of air supplied from an air feeding tube 33 and an auxiliary air feeding tube 35 with respect to the fuel supplying amount supplied from a fuel supplying tube 31 is kept at the most suitable value for obtaining the heat energy at all times. |
