What are the Effects of Atomizer Pressure and Flow?
When the pressure of atomizing agent is increased, the spraying speed of atomizing agent will increase. At this time, if the cross-sectional area of the atomizer nozzle is kept unchanged, the flow rate of the atomizer will increase; If the atomizer consumption is to be kept unchanged, the atomizer nozzle area should be reduced accordingly. As the oil flow or spraying speed can also change when the oil burner is adjusted, the influence of the relative speed of the atomizer and oil stream and the unit consumption of the atomizer on the atomization quality should be discussed.
The relative velocity of the atomizer has a great influence on the average diameter of particles. The larger the relative velocity is, the smaller the average diameter of atomized particles is, and the effect is more obvious in the high-velocity range. Therefore, the atomization quality of the high-pressure oil burner is generally better than that of the low-pressure oil burner. Regardless of the type of oil burner, the atomization quality can be improved by increasing the atomizer pressure (for example, increasing the air pressure on the low-pressure burner).
The unit consumption of the atomizer plays an important role in particle diameter. In the low-pressure burner, due to the small flow rate of the atomizing agent, which generally does not exceed 100m/s, more atomizing agent is required. When the consumption of atomizing agents is too small (less than 25%~30% of the combustion air demand), the atomizing quality has seriously deteriorated. In the high-pressure oil burner, due to the high atomizing agent speed, the unit consumption of atomizing agent can be smaller, generally about 10% of the combustion air demand, and excessive consumption has no significant effect on improving atomization.
