Boiler burners can be broken down in detail from three aspects:
1. Program controller, the parts of the program controller include: electric eye, photosensitive organ, solenoid valve, ignition electrode, ignition transformer, fan, motor, etc.
2. Fuel oil; fuel oil components include oil pump, oil nozzle, oil nozzle seat, filter, etc.
3. Gas: gas components include pressure gauge, gas filter regulator, gas leak detection device, etc.;
What is the working principle of the boiler burner?
The boiler burner is composed of an oil nozzle and an air regulator. The oil nozzle is placed on the axis center line of the air regulator, atomizes the oil into fine droplets, sprays it into the combustion chamber at a certain diffusion angle, and then mixes it with the air sent in by the air regulator and ignites and burns.
One type of oil nozzle is pressure atomization and the other is dual-fluid atomization. The pressure atomization fuel nozzle also consists of three parts. The three parts are diverter plate, swirl plate and atomizer plate. The oil pressure is generally maintained at 2-3 MPa.
In addition to the swirl and direct current types similar to coal powder burners, the air regulator of the oil burner also has a partial swirl type, that is, a flame stabilizer is arranged in the direct current air regulator, so that 10% to 20% of the air flows through the flame stabilizer and produces a rotational motion, forming a central reflow zone at the outlet of the air regulator, so that the oil mist ignites stably to achieve low-oxygen combustion.
The work of the accessories of the boiler burner, how the accessories of the burner work, the accessories are an important part of the boiler burner, and mastering the correct operation method can facilitate the future use effect. Take a look at the working process of the accessory burner.
1. Check the liquid level, temperature and pressure of the boiler;
2. Check the gas pressure, wind pressure and residual flame of the burner. When you use diesel fuel, check the storage capacity of the fuel tank. Check whether the oil pipe and oil pump are filled with oil;
3. Leakage detection stage of the gas valve group: check the air tightness of the gas valve;
4. Purge stage before pre-explosion: open the air damper, purge the furnace, eliminate the residual gas in the furnace, and provide oxygen to the hall to promote the ignition process;
5. Wind pressure detection: ensure the normal operation of the blower;
6. Ignition stage: close the valve of the burner accessory to the ignition position, open the working mode of the ignition transformer and ignition valve of the accessory to realize the automatic ignition function;
7. Confirm that the flame is ignited;
8. Open the air damper to the main fire position, and then open the main gas valve to establish the main flame;
9. Close the ignition valve of the burner and confirm that the main flame has been established. Implement the minimum fire conversion or adjust the flame size proportionally.
