Embodiment Construction
[0030] Such as Figure 1 to Figure 3 As shown, the low-pressure oil film breaking atomization technology of the present invention is specifically: in the gas-liquid two-phase fluid generator, fuel oil and compressed air, steam and other auxiliary gases are formed into a gas-liquid two-phase fluid, and the gas-liquid two-phase fluid includes bubbles flow, slug flow or emulsion flow. The gas-liquid two-phase fluid is sprayed into the furnace through the oil gun, and the injected gas-phase fluid breaks and atomizes the formed oil film at one time by overcoming its strong surface tension, so as to achieve ultra-fine atomization of fuel oil and obtain ultra-fine Fine atomized oil droplets; in the process of primary crushing and atomization, the gas energy is fully and effectively used to achieve the best atomization effect. The gas-liquid two-phase fluid is sprayed from several circular injection holes of the atomization moment provided on the oil gun, and each circular injection ...

The invention discloses low-pressure oil film breaking and atomizing technology and device thereof. The low-pressure oil film breaking and atomizing technology is characterized in that fuel oil and an auxiliary gas are formed into gas-liquid two-phase fluids, the gas-liquid two-phase fluids are jetted into a furnace cavity through an oil gun, and the jetted gas-phase fluids enable a formed oil film to be broken by overcoming the surface tension of the jetted gas-phase fluids so as to realize the superfine atomization of the fuel oil; the outlet of a circular jet hole is provided with a secondary transverse ultrasonic air flow, the jet direction of the secondary transverse ultrasonic air flow is perpendicular to that of the circular jet hole, and the secondary transverse ultrasonic air flow further impacts initially-atomized fuel oil jetted from the circular jet hole to carry out secondary breakage and atomization on the fuel oil. The invention has the advantages of smaller average diameter of an oil drop, high penetrating capability of oil mist, good adjustability of an atomized taper angle and very little change of the average dimension of the oil drop when the viscidity of the fuel oil is enhanced or the ejection force of the oil gun is smaller; and in addition, the invention only needs lower fuel oil pressure of 0.4-0.5 MPa, thereby lowering the pressure of a fuel oil system, reducing the electricity consumption of an oil pump and saving the plant electrical consumption.
Description
technical field [0001] The invention relates to an oil gun atomization technology, in particular to a low-pressure oil film breaking atomization technology and a device thereof for an ignition oil gun during start-up and stable combustion of a pulverized-coal boiler of a thermal power generation unit. Background technique [0002] Coal-fired boiler ignition oil guns in power stations still widely use mechanical atomization technology. The mechanical atomization technology mainly relies on the pressure of the fuel oil itself to convert into jet kinetic energy. The high-speed rotating oil flow is formed through the swirl chamber of the mechanical atomization sheet of the oil gun. After the rotating oil jet is sprayed, it rubs against the air to atomize the fuel, and the average diameter of the oil droplets is relatively large. It is characterized by simple structure, and its disadvantages are poor oil mist penetration ability and poor adjustability of atomization cone angle, a...
