PURPOSE:To permit to conduct surely and safely ignition of an automatic operated burner by a method wherein at the time of automatic ignition of the automatic operated burner, fuel oil feeding pressure to the burner is increased. CONSTITUTION:Upon igniting an automatic operated burner 2, a burner igniting signal 12 is inputted in a flow controller 5 by handling of an interlock relay board 9. And the setting value of the flow controller 5 is sharply increased, signal of which has priority over a signal sent from a pressure transmitter 7 to the flow controller 5 in time lag, thereby a flow control valve 6 is con trolled to open through a high-selecor 10. Being ignited the automatic burner 2, the setting value of the flow controller 5 is excusively controlled by a master signal 4, therefore, the pre-set volume by the master signal 4 is phisically sup plied to a fuel oil main pipe 3. By this constitution, it is possible to increase a fuel oil feeding pressure at the time of igniting the automatic operated burner, thereby, ignition of the automatic operated burner may be conducted safely and surely. |
