Description

Technical Field

[0001] This invention relates to the field of metallurgy, specifically to the structure of a heating burner and a combustion control method. Background Technology

[0002] Most existing melting furnaces, especially steel melting furnaces, are coking furnaces. Coking furnaces have low thermal efficiency and pollute the environment when melting metal materials. Generally, it takes 0.35 tons of coke to melt one ton of cast iron. The melting cost is high and the melting cycle is long. Some furnaces use electric furnaces, but electric furnaces consume a lot of electricity. Melting one ton of cast iron requires about 1,000 kilowatt-hours of electricity.

[0003] Brown's gas, or hydrogen-oxygen mixture, is an active mixture of hydrogen and oxygen produced by water electrolysis. It is defined as a mixture with a precise molar ratio of hydrogen and oxygen in the molecular formula of water. Brown's gas is characterized by its temperature-changing properties, implosion properties, and catalytic properties. It does not produce carbon dioxide or other pollutants during combustion, hence it is known as "water fuel." Compared with traditional heating methods, it has significant advantages. Hydrogen-oxygen mixture can be produced using photovoltaic, wind power, and other methods to achieve energy storage, while releasing a large amount of heat energy in the combustion chamber. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the defects of the above-mentioned technology and provide a hydrogen-oxygen burner structure and usage method.

[0005] To address the aforementioned challenges, this invention discloses a heated burner structure, comprising a combustion chamber and a mixing chamber connected to the combustion chamber. The mixing chamber is sequentially equipped with a compressed air inlet pipe, a hydrogen-oxygen mixture inlet pipe, and a liquefied gas inlet pipe along the gas flow direction. The compressed air inlet pipe extends to the bottom of the mixing chamber, the hydrogen-oxygen mixture inlet pipe extends into the mixing chamber at one end and into the combustion chamber, and the liquefied gas inlet pipe extends into the mixing chamber at one end and into the combustion chamber near the inlet.

[0006] A combustion control method for a heated burner structure includes the following steps:

[0007] Step 1: When using liquefied petroleum gas (LPG), first raise the LPG temperature to 40℃-60℃ using a regulator;

[0008] Step 2: When starting the furnace, first turn on the induced draft fan and the blower, and then turn on the igniter;

[0009] Step 3: After the igniter is running, turn on the LPG switch and the air switch, introduce compressed air into the compressed air inlet pipe, and introduce LPG into the LPG inlet pipe 5. The flow ratio of LPG to compressed air is 1:11 to 1:13.

[0010] Step 4: Start the hydrogen-oxygen generator and deliver hydrogen and oxygen to the combustion chamber 1 through the hydrogen-oxygen mixing inlet pipe 4 for combustion.

[0011] Step 5: When shutting down the furnace, first turn off the hydrogen-oxygen generator, and then turn off the liquefied gas switch and the air switch in sequence;

[0012] Step 6: Shut down the blower and induced draft fan.

[0013] The advantages of this invention compared to the prior art are:

[0014] It makes full use of new energy sources and achieves energy storage effects. It has high combustion heat and produces pollution-free products. No additional environmental protection equipment is needed during the production process, which further reduces production and manufacturing costs. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0020] In the description of the embodiments of the present invention, it should be noted that if terms such as "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of the invention is in use, they are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention. Furthermore, terms such as "first," "second," and "third" are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0021] Furthermore, the use of terms such as "horizontal," "vertical," and "sag" does not imply that the component must be absolutely horizontal or suspended, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.
