  Diesel burner troubleshooting 2

In the troubleshooting of diesel burners, it should be noted that these burners use diesel as fuel and due to the presence of particles and impurities in diesel, it causes these devices to suffer from deposits and cause disturbances in The correct way to operate the device.

In the process of troubleshooting the diesel burner and fixing the problems and defects created in the boiler room burner, there are some common and diverse problems.

Why does the diesel pump pressure fluctuate?

1- The pump gears are worn
2- The diesel filter is damaged
3- The pump has air
4- Diesel has evaporated due to high vacuum
5- The pressure adjustment valve is stuck, the one-way valve is defective
6- The one-way valve is defective
7- The lantern type faucet is pierced
8- The diameter of the suction pipe is small
9- In the two-pipe system, the bypass balls have been removed
10- The diesel source is below the burner, the suction pressure is more than the permissible limit

Why does the flame smoke in the troubleshooting process of the diesel burner?

1- The fan is dirty or loose
2- There is not enough combustion fuel air
3- Fuel and air are not mixed properly
4- The air does not have enough speed and rotation
5- The nozzle is worn, dirty, loose, or the cone size is not correct.
6- The nozzle is far behind the flamethrower
7- The pump pressure is too low
8- The chimney is dirty or blocked
9- There is a problem with the flame spreader
10-The nozzle drips after the magnetic valve
11- The nozzle drips into the combustion chamber
12- The flame hits the walls of the combustion chamber
13-The engine does not have the required speed

Why is diesel consumption high?

1- The percentage of air is high and the amount of CO is low
2- The air does not have the necessary rotation to mix with diesel
3- The front and back doors of the boiler are not sealed and the heat is wasted
4- The combustion chamber and pipes are deposited in the water contact area
5- The pipes of the boiler are smoking
6- The system is full of air
7- The size of the nozzle is not suitable
8- The thermal losses of the building are high
9-Diesel leaks from the source of diesel through the pipeline
10- Diesel pressure is low
11- The working period of the burner is too short, not adjusting the steam pressure control
12- The thermostat or Aqustat is set to a high temperature
13- Air suction is high or low
14- Boiler or furnace is not proportional to the amount of consumption
15-The combustion chamber is not suitable

In the troubleshooting process of the diesel burner, why is the noise of the burner high?

1- The fan makes noise
2- The air adjustment valve is loose
3- The burner is not connected to the boiler
4- The gears of the diesel pump are worn out
5- The suction path of the diesel pump is clogged
6- Diesel fuel needs air, it is necessary to ventilate the fuel line
7- The coupling is defective
8- The burner electric motor is not installed properly
9- There is a problem with the engine bushing or bearing
10-The pump or electric motor are not aligned
11- The ignition trans is faulty and makes noise
12- The chimney damper tee vibrates

Why is the combustion sound so loud?

1- There is no necessary suction on the combustion chamber or chimney
2- The chimney is dirty, its diameter is small or blocked
3- The chimney damper is not adjusted or is completely open
4- Boiler pipes are dirty
5- The size of the nozzle is too big
6- The combustion chamber is not suitable
7- Diesel pressure is too low or too high
8- The mixing ratio of air and diesel is not suitable
9- The air does not have the necessary rotation
10-The fan is small
11- The static pressure in the flame cover is low
12- The working period of the burner is short
13-The nozzle has mass
14-The nozzle is placed too far forward
15-The angle of the nozzle is not correct

Why does the burner turn on and then turn off shortly after?

1- The fuel has run out
2- The suction pipe of the air pump is leaking or clogged
3- There is water inside the diesel source
4- The electrodes are defective
5- The diesel nozzle or filter is dirty

Why does the flame return?

1-Delay in ignition, the need to visit and fix the fault of the control circuit
2- Spark electrodes are not adjusted
3- The power transformer is defective
4- Voltage drop when the burner is turned on
5- The electrodes are covered with carbon
6- The connection of the spark cables to the electrodes is loose or they are connected to the body
7- Good diesel is not powdered, it is necessary to visit and depressurize the diesel pump and nozzle
8- The nozzle is dirty, loose, or too far behind the flame cover
9- The pump pressure is too low
10-The nozzle drips after the magnetic valve
11- It drips into the combustion chamber
12- Presence of water in diesel
13- The amount and pressure of the air is high
14- The chimney does not have enough suction
15- Combustion air speed is high
16- Presence of water in diesel
