oil/gas burner Centrifugal rotation
Oil atomization nozzle
(1) mechanical atomization
Mechanical atomization nozzle is the use of high oil pressure, the oil from the nozzle in the high-speed spray to achieve atomization. Commonly used mechanical atomizing nozzles are centrifugal nipples.
Simple mechanical atomization nozzle is composed of atomized film: swirl chamber, sub-oil parts and nuts and other components, with a certain pressure, the temperature of the fuel, through the oil hole and the oil tank into the tangential groove, get a high speed , And then into the swirl chamber. The oil produces a strong centrifugal rotation in the swirl chamber, causing the grooves to pulsate and eject from the orifices to form hollow conical films. As the oil in the case of turbulence, through the nozzle hole diffusion, combined with centrifugal force, the formation of the surface tension and was crushed into many small oil particles, to achieve the purpose of atomization.
(2) rotor atomization
Its working principle is the fuel oil through the hollow shaft to 3000 ~ 5000r / min high-speed rotation of the cup-shaped device, under the action of centrifugal force, the oil in the rotor tight inside the wall to form a very thin film, along the cup Mouth fly out, and was atomized into a very fine oil. At the same time, the fan blades mounted on the same axis will be a wind along the cup through the guide piece blowing, the direction of rotation of the air and the opposite direction of the oil droplets, so that the oil droplets further atomized.
The oil / gas burner is a device that combines the fuel delivery and atomizing device with the air conditioning device through the circuit. Combined as a whole, called the whole oil / gas burner. It is equipped with automatic control, alarm and protection devices in addition to ensuring better fuel supply to the boiler and burning it completely. There are separate to the foundation, that is, oil system, the wind system separately, so the circuit system is also separated. Depending on the fuel, the oil / gas burner is divided into light oil (kerosene, diesel oil>, heavy oil (residual oil) and oil / gas dual / oil burner.
Oil / gas burners are divided into one level (single stage, second stage, two sections), three stages (three sections) and one type according to the oil nozzle and the number of oil nozzles. Nozzle, two injectors, two with three injectors. Proportional is the oil / gas burner load with the boiler output size of continuous adjustment changes, while the other is based on changes in the number of changes in the nozzle Adjust the size of the boiler output.
