Proportional control system This system is used in medium to large burners, and requires a keen control system. As shown in the figure, when the circulating oil is returned to the oil drum through the solenoid valve to complete the cycle, if the solenoid valve When it is closed, the oil circuit generates pressure, which is sprayed through the nozzle for combustion, the remaining oil flows into the FCV flow control valve, and the proportional motor controls the throttle and FCV in a chain to generate the proportion of flame.
