In this embodiment one, the atomising head 2 is installed in the bottom of drain pan 4, and the bottom of combustion bowl 1 is vertical to be offered and is located the oil through hole 12 directly over atomising head 2. The bottom shell 4 comprises an outer cylinder 42, the air inlet 41 is arranged on the side wall of the outer cylinder 42, an inner cylinder 43 protruding upwards is arranged at the inner bottom of the outer cylinder 42, the outer bottom of the combustion bowl 1 is overlapped on the inner cylinder 43, the atomizing head 2 can be fixed at the center of the inner bottom of the combustion bowl 1 through a screw and is positioned in the inner cylinder 43, the outer bottom of the combustion bowl 1 can be provided with an annular positioning groove 13, the upper end of the inner cylinder 43 is embedded in the annular positioning groove 13, and the positioning structure of the combustion bowl 1 and the bottom shell 4 is not limited to this. The atomizing head 2 is preferably but not limited to a siphon nozzle, high-speed airflow is generated through compressed gas to form certain vacuum degree in the nozzle, the oil is sucked to the nozzle in a siphon mode, oil drops are directly atomized through the high-speed airflow, the atomizing effect is better, and the atomizing degree and the atomizing amount can be controlled by controlling the pressure of the compressed gas and the flow of the oil, namely, the flame size is controlled. Because the granularity of the oil atomized by the air pressure siphon is very small, the surface area is very large, the contact area of the atomized oil with unit mass and air is very large, and the oil is easy to burn at the moment.
In the first embodiment, the ignition needle 3 is installed at the bottom or the side wall of any one of the bottom case 4 and the combustion bowl 1, a mounting hole may be formed at the side wall or the bottom of the bottom case 4 and/or the combustion bowl 1, for example, the ignition needle 3 is H-shaped, two first mounting holes for passing two large poles of the ignition needle 3 and two high-voltage modules for connecting two large poles of the ignition needle 3 to the outside are formed at the bottom of the bottom case 4, two second mounting holes for passing two small poles of the ignition needle 3 are formed at the bottom of the combustion bowl 1, a small high-voltage discharge head of the ignition needle 3 passes through the bottom of the combustion bowl 1 and extends into the pressure combustion chamber a, two small heads of the ignition needle 3 generate high-voltage electric sparks to ignite atomized oil in a specific electric control mode, the atomized oil is continuously supplied and continuously combusted, the ignition effect is better, because the middle part of the ignition needle 3 is just clamped between the bottom of the combustion bowl 1 and the bottom of, the ignition needle 3 belongs to a quick-wear part, and can be replaced only by taking up the combustion bowl 1 during disassembly and replacement.
In the first embodiment, the air inlet 41 is disposed on the side wall or the bottom of the bottom shell 4, and the air inlet 41 may be connected to an air inlet duct 44. The air intake duct 44 may be connected to an air outlet of a blower (such as an air compressor/blower/induced draft fan) through an air supply duct, and provides pressure air to the pressure plenum B. The air inlet pressure of the pressure air chamber B can be reasonably selected according to actual needs so as to form a certain air pressure in the pressure combustion chamber A and promote the full combustion of oil.
In this embodiment one, ventilation hole 11 is the slope through-hole, and the inlet center that the slope through-hole is located 1 lateral wall of combustion bowl is lower than the export center that is located 1 inside wall of combustion bowl, all forms the contained angle on the horizontal plane and on the vertical face between the central line of slope through-hole and the central line of combustion bowl 1, makes pressure air current drive vaporific oil clockwise or anticlockwise rotation, and it is long when having increased the contact of air with the oil. Parameters such as the number, shape, size, and angle of the ventilation holes 11 can be designed reasonably according to actual needs, for example, the shape can be circular or square, and the angle can also be vertical or curved.
In this embodiment, the fuel burner further includes a fire pressing cover 5, and the fire pressing cover 5 covers the mouth of the combustion bowl 1. The fire-pressing cover 5 is provided with at least one fire-spraying hole 51 for communicating the pressure combustion chamber a with the outside atmosphere, for example, a circle of fire-spraying holes 51 annularly distributed as shown in fig. 1 and 2, or a conical fire-pressing cover with one fire-spraying hole 51 as shown in fig. 4, wherein parameters such as specific number, shape, size, angle and the like of the fire-spraying holes 51 can be reasonably designed according to actual needs, for example, the shape can be oval, circular, square and the like, and the angle can be vertical, inclined, bent and the like. Wherein, the total sectional area of the flame spray holes 51 is smaller than the sectional area of the inner cavity of the combustion bowl 1, the airflow can pass through the through hole of the flame pressing cover 5 at an accelerated speed, the combustion of the atomized oil material is further promoted in the accelerating process, and the combustion of the atomized oil material is also promoted by the high temperature of the pressure combustion chamber A.
The working principle of the first embodiment is as follows: when the starting-up is started, the atomizing head 2 atomizes the oil, and the ignition needle 3 generates high-voltage electric sparks to ignite the atomized oil; pressure air provided by an external fan (such as an air compressor, a blower, an induced draft fan and the like) enters a pressure air chamber B through an air inlet guide pipe 44, the pressure air in the pressure air chamber B quickly flows into a pressure combustion chamber A through a vent hole 11, the burning atomized oil is further violently burnt when meeting sufficient oxygen, the fire suppression cover 5 prevents the atomized oil which is not yet ready to burn from being blown away, and the temperature of a furnace core is ensured to be quickly raised; the expanding air of combustion is ejected through the fire ejecting holes 51 of the fire cover 5.
In summary, the combustion of the atomized oil in the pressure combustion chamber a generates a relatively complex environment, such as a high temperature, a pressure slightly higher than atmospheric pressure, a spiral airflow, and a sufficient and long-time contact with oxygen, which are favorable for the mixed combustion of the oil and air, and simultaneously, the design of the flame holes 51 further promotes the complete combustion of the trace fuel in the tail gas, so as to squeeze the chemical energy of the raw oil to the maximum extent, reduce or even not pollute the environment, and control the sufficient combustion of the fuel can reduce the fuel injection amount and reduce the cost. Meanwhile, the pressure cold air in the pressure air chamber B can provide oxygen, and can well cool the combustion bowl 1, so that the service life is prolonged, and the heat insulation effect is achieved.
