Abstract
Description
Technical Field
[0001] The utility model relates to a liquid fuel combustion device with a fairing. Background Art
[0002] In addition to conventional gas combustion devices, there is also a liquid combustion device on the market. This liquid combustion device achieves combustion by heating the liquid, vaporizing it, and igniting the vaporized gas. However, this liquid combustion device has a relatively obvious disadvantage, that is, it needs to be preheated and wait until the liquid is vaporized before it can be burned. Moreover, since the internal pressure of the liquid fuel is too high after heating, the released gas pressure is high, which will produce obvious noise.
[0003] Therefore, it is necessary to make further improvements. Utility Model Content
[0004] The purpose of this utility model is to overcome the above problems. We provide a liquid fuel combustion device with a fairing, which solves the noise problem and does not require preheating.
[0005] To achieve the above-mentioned purpose, the utility model provides a liquid fuel combustion device with a fairing, which includes a burner, an atomizer and a liquid fuel supplier. The input end of the atomizer is connected to the liquid fuel supplier, and the output end of the atomizer corresponds to the input end of the ejector tube of the burner. The burner is provided with a fairing and a fire cover. The fairing is installed on the opening of the burner and forms a lower air cavity with its inner cavity. The lower air cavity is connected to the ejector tube. The fire cover is arranged on the burner and forms an upper air cavity with the fairing. A plurality of through holes are opened on the fairing to connect the upper air cavity and the lower air cavity.
[0006] In one or more embodiments, an upper end of the fairing is provided with an upwardly extending surrounding wall around each through hole.
[0007] In one or more embodiments, the outer edge of the fairing has an annular supporting edge, and the burner is provided with an annular recessed step supporting the annular supporting edge.
[0008] In one or more embodiments, the fairing is in a concave arc shape or a flat shape.
[0009] In one or more embodiments, a drain pipe is provided at the bottom of the burner located at the lower air cavity.
[0010] In one or more embodiments, an air inlet adjustment ring is provided at the input end of the ejector tube, and the air inlet adjustment ring can be moved relative to the ejector tube to be closer to or farther away from the output end of the atomizer.
[0011] Compared with the background technology, the present invention has the following effects: the liquid fuel combustion device atomizes the liquid fuel through the atomizer and outputs it to the burner for combustion, without the need for preheating and waiting, and also solves the problem of high heating and gasification pressure generating noise; in addition, after the gas is rectified by the fairing, the flow direction and pressure of the gas output to the fire cover are stable, which makes the gas combustion condition better and reduces the combustion noise. When backfire occurs, the fairing can also block the backfire, so that the backfire is confined between the fairing and the fire cover, avoiding combustion and explosion inside the burner. BRIEF DESCRIPTION OF THE DRAWINGS
[0012] Figure 1 This is a schematic structural diagram of a liquid fuel combustion device according to an embodiment of the present utility model;
[0013] Figure 2 This is a schematic diagram of the structure after the fairing and fire cover of the embodiment of the utility model are disassembled. DETAILED DESCRIPTION
[0014] In order to deepen the understanding of the present invention, the present invention will be further described in detail below with reference to embodiments and drawings. The embodiments are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.
[0015] Please see Figure 1-2 The utility model provides a liquid fuel combustion device with a fairing, which includes a burner 1, an atomizer 2 and a liquid fuel supplier 3. The input end of the atomizer 2 is connected to the liquid fuel supplier 3, and the output end of the atomizer 2 corresponds to the input end of the ejector tube 4 of the burner 1. The atomizer atomizes the liquid fuel and sprays it to the input end of the ejector tube. The burner 1 is provided with a fairing 5 and a fire cover 6. The fairing 5 is installed on the open mouth of the burner 1 and forms a lower air cavity with its inner cavity. The lower air cavity is connected to the ejector tube 4. The fire cover 6 is covered on the burner 1 and forms an upper air cavity with the fairing 5. The fairing 5 is provided with a plurality of through holes 7 connecting the upper air cavity and the lower air cavity, and an atomizer is used to atomize the liquid fuel, which eliminates the waiting process for preheating and vaporizing the liquid fuel and solves the noise generated by the high-pressure output of the liquid fuel heating and vaporization. The vaporized liquid fuel and air are mixed in the ejector tube and first pass through the fairing. The flow direction and pressure of the gas after the fairing are rectified tend to be stable, and then it is output from the fire cover for combustion, which can achieve better combustion conditions. When the burner is closed, when backfire occurs, the backfire can be prevented from occurring inside the burner by blocking the fairing.
[0016] The upper end of the fairing 5 is provided with an upwardly extending wall around each through hole 7, so that the through hole becomes a gas nozzle for guiding the gas output, making the direction of the gas output more stable and reducing the disturbance of the gas after output that causes unstable gas pressure.
[0017] The outer edge of the fairing 5 has an annular supporting edge 51, and the burner 1 is provided with an annular concave step 8 for supporting the annular supporting edge. The use of this structure to install the fairing has the advantage of being easy to install and remove. Specifically, the fairing 5 is in a concave arc shape or a flat surface.
[0018] The burner 1 is located at the bottom of the lower gas cavity and is provided with a drain pipe 9. The inner wall of the burner in contact with the gas will inevitably absorb and accumulate oil, water droplets, etc., which can be discharged by the drain pipe provided at the lowest position.
[0019] The input end of the ejector tube 4 is provided with an air inlet adjustment ring 10. The air inlet adjustment ring 10 can be moved relative to the ejector tube 4 to be closer to or farther away from the output end of the atomizer 2. The distance between the output end of the atomizer and the input end of the ejector tube can be adjusted according to the weather conditions and combustion conditions at the time. The amount of air introduced can be easily adjusted to ensure that the combustion conditions are in the best state.
[0020] The above are only preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments. Any equivalent modifications or changes made by ordinary technicians in this field based on the contents disclosed in the present invention should be included in the protection scope recorded in the claims.
