How does heating oil burner work?

The system of oil burner is based on the circulation of water, which is heated in the boiler and transferred with the circulator to the radiators, as the company καυστήρες Μπότης explain us. Radiators transmit heat from the water to the home environment. So the water cools and goes down to the boiler, where it is reheated to circulate again and repeat the same process.

These facilities are basically the oil boiler (boiler), where the water coming from the bodies is heated and the burner that gives the necessary fire, using oil as fuel. There is also the flue , which leads the flue gases from the boiler to the base of the chimney and of course the hot and cold water pipes, which are connected to the boiler and the expansion tank, located inside the boiler room or on the roof.

What is an oil boiler and what is a burner?

The oil boiler is probably the most important part of a central heating system with oil, gas or LPG, as it is the one that gives the heat generated by the combustion to the water circulating in the pipes and heats it.

The burner, of course, is the medium that burns the various fuels to produce heat.

Boilers are distinguished in cast iron and steel in terms of their construction material, in wall or floor (in terms of how to connect gas and LPG boilers), while in recent years has emerged a new category related to the technology they use and are the condensing boilers.

How heating oil boiler works?

The oil burner is controlled by automation. In order to start its operation, its electronics must receive an electrical command (phase) from the thermostat of the boiler panel. When this is done then the following happens in turn:

The electronic commands the burner motor. This starts to spin and with it the impeller and the oil pump start to spin. This takes a while to happen in burners with a pre heater. The oil must first be heated in the burner oil pipe and then the above processes must begin.

The transformer starts working and a spark is created at the end of the electrodes above the nozzle. In some burners this happens when the electromagnetic oil valve opens and the injector starts spraying oil.

After a few seconds (2 to 15 depending on the type of burner) and as long as there is no flame in the burner, the oil solenoid valve opens. A certain amount of fuel is now pressed towards the injector). This is how the oil is sprayed and mixed with the air already provided by the impeller. This air-oil mixture is ignited by the electrode spark.

The photocell now receives the light of the flame and after a few seconds commands (via the electronic) to stop the transformer, while the burner continues to operate.
When the power supply to the electronics is cut off because the room thermostat or the burner thermostat from the boiler panel or for another reason commands, the burner stops working. In other words, the engine stops and the electromagnetic oil valve closes.

Why is it necessary to maintain the burner – oil boiler?

A well-maintained and well-regulated burner-boiler system increases the overall thermal efficiency of the installation.
Reduces fuel consumption by up to 50%. Increases the life of the burner-boiler system and reduces the chances of serious damage. Maintenance costs are not very high and are amortized by the oil savings achieved by the smooth operation of the burner.

Maintaining the heating system ensures the safety of both you and your children. The appropriate period for the maintenance of the burner – oil boiler. The maintenance period of the oil boiler-burner complex begins with the end of the winter season (April to May).

Thus, you protect the boiler from corrosion since the corrosive deposits are removed in time while at the same time the quality of the work is definitely much better since the installer-maintainer ( burners ) during this period has the possibility of better planning of his working time.

The main tasks in the maintenance of the burner – oil boiler

Cleaning and maintenance of the burner and oil boiler

  1. Appropriate burner settings for fuel economy and emission minimization
  2. Exhaust gas control
  3. Circulator control
  4. Automation control
  5. Checking the good operation
  6. Replacement of spare parts when necessary
  7. Burner – oil boiler

How long does a maintenance take?

In simple cases the maintenance of a burner – oil boiler up to 150000kcal can take from forty minutes to an hour.

Repair and maintenance

During the maintenance process of the individual household boiler – oil burner , the following workgroups will be performed (indicatively mentioned):

Burner cleaning – oil boiler Combustion chamber, ash

Cleaning – maintenance of a burner – oil boiler , is one of the tasks that must be done before turning on the central heating.

  1. Initial installation, maintenance – replacement & operation of oil burner.
  2. Cleaning of the heating inner surface (combustion chamber) and the air ducts in the oil boiler.

Boiler cleaning is done with special wire brushes which detach the residues from the flame chamber and the flame tubes of the boiler. Residues are removed with a high-efficiency vacuum cleaner.

  1. Dry cleaning of oil boiler for water or boilers.
  2. Dry cleaning of oil boiler from ash, soot & combustion residues.

Inspection and cleaning of burner components Nozzles, pins, tamper

An oil boiler burner consists of a set of components and instruments that are mounted on the burner body and must be inspected by qualified technicians.

  1. Restoration of the thermal insulation of the outer surface of the boiler and the piping of the boiler room.
  2. Service – Inspection and cleaning of components in burner – oil boiler.
  3. Cleaning or replacing the nozzle (fuel injector) in an oil burner.
  4. Cleaning the pins or ignition pin on an oil burner.
  5. Adjustment in the air tamper (for intake air for mixing with oil).
  6. Cleaning and measuring an oil pump in an oil boiler burner.

Filters and oil tank leak control and cleaning

The oil tank is one of the most important elements of a central heating installation (oil boiler). The oil filter is placed on the supply line from the tank to the burner.

  • Check, clean or replace filters and gasket in oil boiler.
  • Cleaning the oil tank from rust, mud, water (after evacuation).
  • Check the oil piping from the tank to the burner.
  • Leakage check in the oil pump (tightening of the nuts, replacement in flanges).
  • Leakage and altitude difference check in the oil tank.
  • Installation in the oil tank combustion improvers – injector cleaners.
