The selection of oil and gas boiler burners should be based on the structural characteristics and performance requirements of the boiler body, combined with the user's operating conditions, and make a correct comparison.
Generally, you can choose according to the following principles:
1. Select the fuel according to the type of fuel used by the user. The fuel types include liquid fuel oil kerosene, diesel, heavy oil, residual oil and waste oil; gas fuel oil city gas, natural gas, liquefied petroleum gas, and biogas. The fuel used should have necessary analytical data:
Kerosene and diesel oil should have calorific value and density; heavy oil, residual oil and waste oil should have viscosity, calorific value, moisture, flash point, mechanical impurities, ash content, freezing point and density; gas should have calorific value, gas supply pressure and density .
2. Select the nozzle atomization method or gas combustion type in the oil burner according to the boiler performance and furnace structure.
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 adapt to the furnace structure. The air required for fuel combustion is supplied from the root of the flame to evenly mix the oil mist or gas with the air speed to ensure complete combustion.
4. The burner adjustment range must be large to adapt to changes in boiler load and ensure complete and stable combustion under different working conditions.
5. The energy consumed by fuel atomization and digestion should be less, and the resistance of the air adjustment device should be small.
6. The impact of flue gas emissions and noise must meet the requirements of environmental protection standards. Mainly, the emissions of SO2, CO and NOx must be lower than international regulations. Low NOx and low noise burners 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 should be selected that has a simple structure, reliable operation, is easy to adjust, control and repair, and is easy to realize automatic control of the combustion process.
9. A comprehensive comparison of burner brands, performance, price, service life and after-sales service should be made.
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.
