How to debug the Riello burner, the Riello burner cannot be started

When commissioning, first adjust to about 1 2 of the air supply pressure, and test run the valve leak detection program. The control system is set in standby condition, the combustion device is started, and the pilot fire is carried out. If the initial ignition fails, you can try to adjust the ignition liquefied gas pressure and the opening of the combustion damper during ignition, and test the ignition again until normal ignition.

Open the main valve 1 and the shut-off valve of the long open flame, and test the long open flame. Liquefied gas is turned off after a period of time. Operate in "standby" mode and observe the flame condition of the open flame. Adjust the air distribution (Chang Ming Huo damper) and gas volume (Chang Ming Huo manual adjustment butterfly valve).

Whether nitrogen needs to be added when the flame is put into operation is determined by on-site commissioning. Switch to the "Main Combustion Operation" mode and put into the main combustion. Gradually increase the load, observe the flame, adjust the damper and gas opening at each stage of combustion load, so that the air-fuel ratio is appropriate.

Check whether the gas quality meets the requirements and is stable. Whether the compressed air pressure is normal. The ignition liquefied gas is controlled at 10kpa after pressure regulation; The mixture is controlled at 10kpa after pressurization.

Before and after each start and stop of the burner, the boiler furnace should be fully purged to remove residual gas. Before starting, check that the gas pneumatic shut-off valve is in the closed position, and check that the damper valve plate and the gas butterfly valve are in the "zero" position. After the burner stops running, do not immediately touch the parts close to the flame to avoid burns.

Hello Kiss is happy to answer this question for you. The Riello burner does not start as follows:1

Press the mother flame start button on the combustion control panel. After the mother flame work indicator light is lit for 10 seconds, confirm that the mother flame is ignited. If the mother flame indicator is extinguished within 10 seconds, the combustion fault alarm buzzer on the combustion control panel sounds, which means that the ignition has failed; It is necessary to wait for 60 seconds and then manually press the fault reset button of the program controller to restart the mother fire button.

2. After the mother flame is ignited normally, the operator confirms whether the mother flame is ignited through the burner observation hole. After confirmation, press the fire start button on the burner control panel, after a delay of a few seconds, after the fire work indicator light is on, the operator in front of the furnace should slowly open the load regulating ball valve, and at the same time increase the gas air in proportion until the flame presents the main blue and reddish best. 3. After the fire is ignited and stabilized, check whether the gas supply pressure of the main pipeline is within the normal range.

4. The fan is started, enters the pre-blowing stage, and the equipment is checked to confirm that it is in a normal state. 5. Observe the gas and air pressure indications, and confirm that the burner operation permission instructions are given. 6. Press the combustion control button on the combustion control panel, and the combustion controller enters the combustion start program.

7. The ignition task of taking over the Ming mother fire has been completed. The operator should turn off the mother flame on the panel in time, press the blind button, cut off the mother flame and keep the fire burning. 8. During the combustion process of the fire, the operator can adjust the size of the flame (load) at any time according to the process requirements.

When the process requires a short period of fire, the operator should turn on the mother fire switch to keep the mother fire, and then turn off the fire switch. 9. Adjust the operating handle of the gas valve and air valve, which can be adjusted in stages to ensure that the load output of the burner meets the process requirements. 10. Shutdown operation:

For temporary shutdown, the fire should be turned off first, then the combustion control switch, and finally the stop button.

The Riyalu burner is faulty**, and the red light is displayed because the red light has been lit before the power loss, and it cannot be automatically reset without manual reset. Press the reset button and wait for no more than 3 seconds to turn the yellow light, let go, the burner starts to start, and when the green light is jumped, because the power of the burner is too large at this time, a little bit of a sound (bang) is heard, and it is suffocated, and the electric eye does not establish a stable flame signal to the program controller, the program controller is locked, and the red light is immediately turned on again.

Riello burner failure and treatment method:

1. After the power is on, the yellow light of the machine is on, and the red light is on for a while, and all parts of the machine do not move.

Cause of the fault and elimination method: This is the failure of the self-test to start, check the wind pressure switch, unplug the wind pressure signal line, power off, connect the signal line together, restart the machine, the fan starts to turn, disconnect the air pressure switch signal line, can burn normally, then the wind pressure switch or fan or pressure pipe or smoke exhaust system failure.

2. After the machine works for a period of time, the ignition is not ignited again, and the artificial restart can burn normally, due to the analysis, it may be that the gas pressure changes, and the main flow of the valve group can be adjusted, if the flame is red during normal operation, the main flow rate will be reduced; If it is a blue fire, the main traffic will be increased.

3. The furnace pressure caused by the machine combusting, vibration, and excessive gas pressure is too large, so adjust the gas pressure. (Photo by Li Linwei of Pacific Automobile Network).

The Yalu River burner has a fault code and displays a red light, because the red light has been lit before the power failure, and it cannot be automatically reset without manual reset. Press the reset button, wait no more than 3 seconds, turn on the yellow light, let go, the burner starts to start, jump to the green light. Because the power of the burner is so high at this time, when you hear a loud noise, it will go out.

The electric eye does not establish a stable flame signal for the programmer, the programmer is locked, and the red light will immediately come on again.

Fault and treatment of Yalu River burner:

1.After the machine is turned on, the yellow light is on, then the red light is on, and all parts of the machine do not move.

Cause of the fault and troubleshooting method: This is the failure of the self-test on the boot, check the air pressure switch, unplug the air pressure signal line, turn off the power supply, connect the signal line together, restart the machine, start the fan, disconnect the air pressure switch signal line, it can burn normally, and then the air pressure switch, fan or pressure air intake pipe, or the smoke exhaust is not smooth, etc.

2.After the machine works for a period of time, it will ignite again without judgment, and it can burn normally after manual restart. According to the analysis, it may be that the air pressure has changed, and the valve manifold main stream can be adjusted. If the flame is very strong during normal operation, turn off the small mainstream; If it is an orchid product, increase the mainstream.

3.The combustion and vibration of the machine, as well as the excessive gas pressure leads to a high furnace pressure and therefore a decrease in the gas pressure.

Millions of car purchase subsidies.

Use the multimeter AC 250 volt gear, measure the burner terminal BM 1 and 2 pins, the multimeter shows 220 volts, normal.

Use the multimeter resistance 10 gears to measure the burner terminal BM 3 and 5 pins, and the limit temperature control switch is connected normally.

With AC 220 volts, test the motor separately, and the motor starts normally. Since the motor can start normally, it means that the oil pump is not stuck.

Measure the photosensitive tube with a multimeter resistance of 1k, the resistance value of the sensitive tube when there is no light in normal time should be greater than 20k, and the resistance value when seeing light should be less than or equal to 1k. The measurement results are 1k with and without light, indicating that the photosensitive tube has been damaged and replaced.

When the power is turned on, the burner still can't start normally, and even the motor doesn't rotate, but the 503SE controller has acted. To determine whether the controller is moving, just put your hand on the controller, if there is a slight vibration, it means that the controller has moved.

Because the motor does not rotate and it is good to test the motor separately, it indicates that there is a problem with the connecting wires that supply power to the motor inside the burner.

Unplug the 503 SE controller and check the connecting wire of the motor power supply in the controller base, and it was found that the N wire of the control motor is not connected to the burner terminal BM 2, while the 15 pins of the controller base are connected to the burner terminal BM 2.

At this time, the 15 and 17 pins are shorted with wires, the power supply is turned on, the burner is started, and the motor is working.

After normal, when the copper skin is removed, it turns out that the copper skin is corroded and cracked, causing the N line to be blocked. Because the crack is just pressed with a wire, it is generally not easy to find.

After the burner is started, it does not ignite, and soon the controller will give an alarm.

The ignition transformer was tested separately with AC 220 volts, and the sparks between the ignition rods could be observed from the fire viewing hole. This indicates that the ignition transformer is good, but that there is a problem with the power supply provided to the ignition transformer by the 503 SE controller.

The power supply of the ignition transformer is provided through the internal contacts of the 503 SE controller, and it can be judged that there is something wrong with the 503 SE controller.

Because there was no new controller at that time, I only opened the outer part of the controller and carefully observed the contact provided to the power supply of the ignition transformer.

After gently grinding with fine sandpaper, turn on the power supply and test the burner to start ignition, and the large and small fires work normally.

A Riello burner used in a boiler lit several times before it could start working, and the cause of the failure could never be determined. Then the situation is more serious, no matter how it is not working, pull out the gun head for ignition test, there are sparks at the top of the two high-voltage lines, the nozzle has atomized light oil sprayed out, and the fan works normally. Installed in situ and then ignited, the fault is still the same.

This type of burner maintenance, troubleshooting related components, judged to be the relative ratio of air to fuel has not been adjusted. But as a rule of thumb, the main root cause is that the current air volume is large, and the spark from the transformer is not enough to ignite the fuel. In the case that you used it well in the past, there are the following possibilities:

1) The transformer power is insufficient.

2) The pressure of the burner oil pump is insufficient, the atomization is not good, and the spark cannot ignite 3) The relative back pressure is reduced to negative pressure due to other reasons.

The solution when you can't find a professional repair for your burner:

Replace transformers, oil pumps, and grease nozzles, and clean oil circuits.

Replace the areas that may have problems, and then adjust the damper and oil pressure.

Answer: The reason for the failure of Riello may be the insufficient power of the transformer, the insufficient pressure of the burner oil pump, the poor atomization, and the failure of the spark to ignite; Other reasons that cause the relative back pressure to decrease to negative pressure in the solution to the burner are:

21. Replace transformers, oil pumps, and grease nozzles;

32. Clean the oil circuit and other parts that may have problems;

42. Then adjust the damper and oil pressure.

Why is the ignition normal, and the flame detector burns after the fire is sprayed, what is the fault?

If it is a newly installed pipeline, all pipes should be carefully checked for installation reliability and tightness.

Users who use a separate gasification station should ensure that the gas supply volume and gas supply parameters meet the requirements of safe combustion.

The operator reads the instruction manual of the equipment and is proficient in the knowledge and methods of safe operation.

Check whether the gas valve is open before each start-up, otherwise the burner will not work.

Start the power control on the control cabinet Jing Tongmin trembling button, at this time the digital display will show the current furnace temperature, Xin'an furnace body temperature is the ambient temperature.

Start the fan control button, the fan installed on the furnace body will work, and if the fan is damaged by the control cabinet, it will automatically protect from entering the next operation.
