I believe that many friends will have some problems more or less when choosing burner products. To solve this problem, we must first understand the burner. The selection of fuel oil and gas boiler burners should be based on the structural characteristics of the boiler body and Performance requirements, combined with user conditions, make a correct comparison.
Generally, you can choose according to the following principles:
1. Select according to the type of fuel used by the user, such as liquid fuel oil kerosene, diesel oil, heavy oil, residual oil and waste oil; gas fuel oil city gas, natural gas, liquefied petroleum gas, biogas. The fuel used should have the necessary analysis data: Kerosene and diesel should have calorific value and density; heavy oil, residual oil and waste oil should have viscosity, calorific value, moisture, flash point, mechanical impurities, ash, freezing point and density; There should be calorific value, air supply pressure and density.
2. According to the boiler performance and furnace structure, select the nozzle atomization method or gas combustion type in the fuel burner.
3. The output power of the burner should match the rated output of the boiler, and the shape of the flame, such as length and diameter, should be selected to make it suitable for the furnace structure. The air required for fuel combustion is supplied from the root of the flame, so that the oil mist or gas is mixed with the air speed evenly to ensure complete combustion.
4. The adjustment range of the burner should be large, which can adapt to the needs of boiler load changes and ensure complete and stable combustion under different working conditions.
5. Fuel atomization and digestion consume less energy, and the resistance of the air regulating device is smaller.
6. The impact of flue gas emission and noise must meet the requirements of environmental protection standards, mainly that the emissions of SO2, CO and NOx must be lower than international regulations, and burners with low NOx and low noise should be selected.
7. Integral or split burners should be selected according to the specific conditions of the boiler and user requirements.
8. A burner with simple structure, reliable operation, easy adjustment control and repair, and easy automatic control of the combustion process should be selected.
9. A comprehensive comparison should be made of the burner brand, performance, price, service life and after-sales service.
10. In addition to overcoming the resistance of the boiler body, the wind pressure of the burner should also consider the resistance of the flue gas system.
