Description

Technical Field

[0001] This utility model belongs to the technical field of burners, specifically relating to a fuel self-heating gasification burner structure. Background Technology

[0002] A fuel self-heating gasification burner is a combustion device that achieves fuel self-heating gasification through internal heat exchange. Its core structure typically includes a fuel supply system, a gasification chamber, a combustion chamber, a heat recovery unit, and a control system. In the gasification chamber, the fuel is converted into combustible gas through high-temperature pyrolysis or partial oxidation, and then fully combusted in the combustion chamber. During the process, the waste heat generated by combustion is used to preheat and gasify the fuel, forming an energy cycle.

[0003] Current burner structures suffer from slow steam generation rates, failing to meet immediate steam demand. Furthermore, manual or imprecise water inlet control can easily lead to unstable water levels, causing dry burning damage or overflow malfunctions. In addition, the large water storage tank has high thermal inertia, resulting in longer heating times and increased energy consumption. Untimely liquid level adjustment can also reduce steam pressure stability, affecting equipment operating efficiency and service life. Utility Model Content

Detailed Implementation

[0020] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0022] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0023] Example

[0024] Reference Figures 1-4 This is an embodiment of the present utility model, which provides a fuel self-heating gasification burner structure, including a shell 110, a connecting plate 120 fixedly installed on the top of the shell 110, a water inlet pipe 130 fixedly installed on the top of the connecting plate 120, a water storage tank 140 is provided at the connection between the water inlet pipe 130 and the shell 110, and a float ball 150 is provided in the inner cavity of the water storage tank 140.

[0025] The integrated design of the outer shell 110 and the connecting plate 120 achieves a compact structure; the combination of the water storage tank 140 and the float 150 enables water level regulation within a limited space, reducing the overall volume while ensuring basic functionality. The design of the water inlet pipe 130 directly connecting to the water storage tank 140 simplifies the water circuit layout and reduces the risk of leakage.

[0026] Specifically, one end of the float 150 is movably sleeved at the end of the inlet pipe 130, and the other end of the float 150 is fixedly installed with a limit block 160.

[0027] The float 150 has a structure in which one end is connected to the water inlet pipe 130 and the other end is equipped with a limiting block 160. This structure allows the float 150 to float freely without detaching from the water inlet pipe 130, thus avoiding jamming or falling off. This design improves the reliability of liquid level control and is especially suitable for high-frequency water replenishment scenarios.

[0028] Furthermore, the diameter of the limiting block 160 is larger than the diameter of the inlet pipe 130, and the diameter of the float 150 is smaller than the diameter of the inlet pipe 130.

[0029] The setting that the diameter of the limiting block 160 is larger than that of the inlet pipe 130 effectively prevents the float 150 from being sucked into the pipe; the diameter of the float 150 is smaller than that of the inlet pipe 130 to ensure smooth water flow. The combination of the two can accurately control the range of water level fluctuations, taking into account both anti-clogging and adjustment accuracy.

[0030] Preferably, a connecting flange 170 is fixedly installed on the outer side of the housing 110, and a handwheel 180 is hinged to the outer side of the connecting flange 170.

[0031] The connecting flange 170 provides a standardized interface for quick assembly with other equipment; the hinged handwheel 180 is designed to allow for manual adjustment or emergency shut-off, enhancing operational flexibility while reducing reliance on external control components.

[0032] Furthermore, the inner cavity of the outer casing 110 is provided with a combustion chamber 190, and the side wall of the combustion chamber 190 is embedded with a fuel nozzle.

[0033] The combustion chamber 190 is integrated into the inner cavity of the outer shell 110, and fuel is directly injected through the fuel nozzle, which shortens the ignition distance and improves combustion efficiency. This integrated structure reduces heat loss and is especially suitable for the high-temperature environment requirements of miniaturized burners.

[0034] Furthermore, the combustion chamber 190 is provided with a vaporization disc 111, and vaporization holes 112 are distributed in a ring on the outer side of the vaporization disc 111.

[0035] The layout of the vaporization disc 111 and its annular vaporization holes 112 enables the fuel to vaporize evenly at high temperatures, avoiding localized carbon buildup; the distribution of the vaporization holes 112 optimizes the airflow path, promotes full mixing of combustible gas and air, and improves combustion stability.

[0036] Furthermore, one end of the outer casing 110 is connected to a steam outlet pipe 113, which is connected to the combustion chamber 190.

[0037] The steam outlet pipe 113 is directly connected to the combustion chamber 190, which utilizes the waste heat of combustion to quickly generate steam and reduce energy loss. The path design of the steam outlet pipe 113 can guide the directional output of high-temperature steam, improve the thermal energy utilization efficiency, and is suitable for application scenarios that require instant steam.

[0038] In use, the inlet pipe 130 fills the water tank 140 with water, and the float ball 150 pushes the limit block 160 to close the inlet as the water level rises, thus achieving automatic water level control.

[0039] Fuel is injected into the combustion chamber 190 through a nozzle and fully vaporized and burned in the annular vaporization hole 112 of the vaporization plate 111 to produce a high-temperature flame. The water in the water storage tank 140 is rapidly heated and vaporized, and the generated steam is output through the steam outlet pipe 113. At the same time, the residual heat of combustion continues to heat and maintain the steam pressure. The float ball 150 reopens the water inlet to replenish water as the water level drops, and the cycle repeats to achieve a continuous and stable steam supply.

[0040] In summary, the coordinated design of the miniature water tank 140 and the high-efficiency combustion chamber 190 achieves a balance between rapid steam generation and stable operation: the miniature water tank 140 significantly reduces thermal inertia, enabling the heating element to quickly convert a small amount of water into steam; the automatic water level control system composed of the float 150 and the limiting block 160 accurately maintains the liquid level within a limited space, preventing both dry burning and overflow.
