Oil burners in fuel are an integral part of oil heating appliances. In the oil boiler, the burner must be adjustable, depending on the changing parameters of the fuel oil. See what are the most important things related to oil burners.
The advantage of oil boilers is that after replacing the burner, the oil furnace can also be operated as a gas. There are also produced dual-fuel burners enabling the change of fuel from oil to gas and vice versa, without the need to replace the burner. However, due to the high price, they are rarely used in boilers intended for single-family houses.
Oil Burner and Gas Burner in heating boilers sprays fuel oil or allows it to evaporate. During this process, the fuel intensively mixes with the air and only a mixture of oil and air is burned.
A proper oil quality is a prerequisite for the proper operation of the oil burner. The most important for the course of the combustion process is kinematic viscosity. To get the right viscosity, you need to heat the oil. In the burner, the oil is heated by an electric oil heater. It is integrated with the nozzle and has a variable power range. The heater adjusts its electrical power to the instantaneous heat demand, thanks to which it minimizes the amount of energy consumed. After the fuel has reached a predetermined temperature, e.g. 80 ° C, the thermostat gives a signal to the controller. The controller first starts the fan, then the ignition system, and then opens the shut-off valve for the oil supply. The resulting oil-air mixture ignites, as indicated by the flame detector.
If the flame disappears during the burner operation, the oil supply is immediately interrupted. The device attempts to restart the burner and ignite the mixture. However, if the mixture does not ignite at the programmed time, the burner will be blocked.
After starting and adjusting the burner, the control electronics allow you to set the minimum amount of oil consumption. If the oil flow is reduced (for example, by 10% due to a blocked nozzle), a service inspection signal will appear on the display.
In order to achieve total and energy-saving combustion, the burner must be perfectly matched to the boiler. Otherwise, the boiler will have lower efficiency, and hence – will use more oil to produce the same amount of heat.
Oil burners – types
Fan burners can be one- or two-stage. In boilers with one-stage burners, the capacity change occurs by turning the burner on or off. Boilers with two-stage burners on the first stage work with less power, on the second – with nominal. Two-stage burners ensure more economical operation of the heating system. Rebar Bender is equipped with a security system controlling the system operation, and in the event of a malfunction, switching off the burner and shutting off the fuel supply.
A two-stage burner better than a one-stage burner. A properly selected oil burner guarantees durability and high boiler energy efficiency as well as minimizing pollutant emissions.
