How to Start and Operate a Natural Gas Burner
How to Start and Operate a Natural Gas Burner
A. The main power switch is closed, the thermostat is closed, and when the working voltage of the power supply system reaches the operating value of the motor, the centrifugal fan motor is connected to work. Tunnel ventilation with centrifugal fan and pre-purging. For burners equipped with air inlet valve-operated AC servo motor, the AC servo motor is connected, the air inlet valve is opened to the corresponding position of the secondary fire, and the used centrifugal fan ventilates to the engine combustion chamber tunnel to complete the front purging.
B. After the blowing is completed, the intake valve returns to the first level fire position. After the ignition transformer runs for three seconds, the first level fire ignition valve and valve open simultaneously. The burner gradually put funds into operation. (The total flow controller can set the total flow of natural materials during operation in advance.)
C. After the flame occurs, the fire detector detects the flame and carries out the entire ignition process. (If there is no flame, about 2 seconds after the first level valve is opened, all equipment enters the safety locking position, press the calibration button to open the device, and then carry out the rear blowing.)
D. After performing the actual operation of setting the first-level fire, turn off the burner, connect the power circuit of the second-level fire thermostat, connect the main power switch, restart the burner, and prepare to adjust the second-level fire in advance.
E. Close the main switch of the power supply and the power switch of the device, ignite the burner, automatically enter the second stage flame, and then observe the flame’s appearance. Adjust the total flow rate of gas and natural materials as needed.
F. When the temperature or working pressure of the steam boiler exceeds the preset value of the second-stage thermostat or pressure controller, the second-stage thermostat or pressure controller will cut off, and the second-stage flame will stop running. Only the first stage flame will operate. If the temperature and working pressure still exceed the rated value, the heating furnace thermostat will cut off, and the burner will stop running. On the contrary, if the second-stage flame stops running and the temperature and working pressure of the heating furnace is less than the preset value, the second-stage flame will burn vigorously again.
G. During the operation process, if there is a problem during one stage, it will cause the burner to stop working, and it can only be restarted after fault detection.
