If it is an ignition failure, how to judge it? First, start the Riello burner three times in a row. If it does not ignite and burn, it will be judged as an ignition failure, and corresponding inspections are required to eliminate the failure. The blower runs normally at ignition and the program is correct.
1. If the gas source is faulty, check whether the pressure of the natural gas is normally maintained at 3-5kpa. If it is too high or too low, it will cause misfire. Solution (regulate the pressure of natural gas and set the pressure).
2. If the damper is faulty, check the size of the damper. When the damper is too large, it is easy to fail to ignite many times. How to deal with it;
3. If the ignition electrode or ignition transformer is faulty, the ignition transformer does not ignite, or the ignition electrode is too dirty and the position is wrong, ignition failure will occur. Solution (test whether the ignition transformer is ignited, clean the ignition electrode, and adjust the ignition gap to maintain 2-3mm).
4. If the gas valve group is faulty, the valve group will open in time during normal ignition, and the sound of opening can be heard. If it cannot be opened, no flame will be established. The solution (check the valve group coil and adjust the opening degree of the valve).
5. The ignition controller is faulty. All ignition programs are issued by the controller. If the controller is damaged, it cannot be ignited normally. Processing method; (replace the controller).
What is a stall failure?
(1) When the burner is running and burning normally, the fire is suddenly extinguished, which is a flameout failure.
(2) After the flame fluctuates due to unstable gas source, extinguish the fire and deal with it; adjust the pressure and restart.
(3) When the flame detector is faulty, the flame detection probe is grounded, or when it is too dirty, the normal flame cannot be detected, and the flame goes out. Treatment method: adjust the position of the probe and clean the surface of the probe. Restart.
(4) Circuit failure The power supply is unstable or lacks a phase, causing the flame to go out during the process. Solution: Contact an electrician to check the power supply and wiring.
The burner does not start fault Press the start button for a long time and the burner does not start 1 external chain fault The external temperature or pressure control does not reach the lower limit of the start; check the temperature or pressure setting value. 2. The internal interlocking of the burner does not pass. When the air pressure is too high or too low, when the air pressure switch is normally closed but not closed, and when the damper mechanism is not in place, it will appear, and check it step by step. 3 Program controller failure is not reset, reset again.
(5) Overheating protection of the fan motor, reset the thermal relay.
(6) Check whether the start button of the control cabinet is normal.
6. Circuit failure Check the circuit to see if the starting signal is normal and whether the voltage insurance is normal.
