Description

Technical Field

[0001] The invention relates to the technical field of gas combustion, and in particular to a highly efficient and energy-saving gas complete combustion method. Background Art

[0002] In traditional gas combustion technology, atmospheric combustion method is usually adopted. This method relies on a large gas discharge port to burn at a high gas flow rate. This atmospheric combustion method is widely used in household and commercial gas appliances, including gas stoves, water heaters, heaters, burners, gas ovens and large gas heating equipment. However, the traditional atmospheric combustion method has the following significant problems:

[0003] 1. Incomplete combustion: Due to the large gas flow, the problem of incomplete combustion is relatively common. This results in the incomplete combustion of the gas, and part of the gas is directly discharged into the air, which not only wastes energy, but also produces a large amount of harmful substances, such as carbon monoxide and hydrogen hydroxide. These harmful substances have significant harm to the environment and human health, and may cause carbon monoxide poisoning and skin damage.

[0004] 2. Low thermal efficiency: In the traditional atmospheric combustion method, the heat dispersion during the combustion process makes the combustion calorific value unable to be fully utilized. This not only affects the heating effect of the gas equipment, but also leads to the problem of low energy utilization.

[0005] 3. Poor energy-saving effect: The traditional atmospheric combustion method has incomplete combustion and low thermal efficiency, resulting in large gas consumption and serious energy waste. Especially in the catering industry, the problem of gas waste is particularly prominent, causing huge economic losses.

[0006] 4. Safety hazards: Due to incomplete combustion and large amounts of gas emissions, traditional gas equipment poses significant safety hazards during use, such as carbon monoxide poisoning risk and fire risk.

[0007] Therefore, how to achieve complete combustion of gas and improve combustion efficiency and reduce emission of harmful substances has become a technical problem to be solved by the present invention. Summary of the invention

[0008] The technical problem solved by the present invention is to provide an efficient and energy-saving gas complete combustion method in response to the defects existing in the above-mentioned prior art, so as to solve the problems of incomplete gas combustion, low thermal efficiency, high emission of harmful substances and serious energy waste raised in the above-mentioned background technology.

[0009] In order to solve the above technical problems, the technical solution adopted by the present invention is as follows:

[0010] A highly efficient and energy-saving gas complete combustion method comprises the following steps:

[0011] Step 1, the gas is initially burned through a tiny gas discharge port, the diameter of the tiny gas discharge port is 1.0 mm to 2.5 mm, the gas is delivered to the gas discharge port through a gas delivery pipeline, and the diameter of the gas discharge port is smaller than the diameter of the gas discharge port of the traditional atmospheric combustion method, so as to achieve precise control of the gas flow rate;

[0012] Step 2: During the initial combustion process, the gas is ignited by an electronic igniter, and the gas flow rate and flame size are controlled by the electronic igniter to ensure that the gas reaches the required combustion temperature and combustion efficiency during the initial combustion;

[0013] Step 3, during the initial combustion process, the incompletely burned gas flow is discharged to a focus burner, wherein the focus burner includes a reflective surface whose back is invisible, and based on the principle of light reflection, the incompletely burned gas flow is reflected and focused to the bottom of the pot to achieve high-temperature and efficient combustion;

[0014] Step 4, the fire-focusing burner performs secondary combustion on the incompletely burned gas flow. During the secondary combustion process, the combustion temperature is controlled between 800 and 1000 degrees to ensure complete combustion of the gas;

[0015] Step 5: During the secondary combustion process, the flame and heat are concentrated to the bottom of the pot through the light reflection and focusing function of the fire-focusing burner, so as to achieve uniform heating while avoiding excessive local temperature and ensuring uniform heating of the pot;

[0016] Ultimately, the above steps can achieve complete combustion of the gas, maximize the release of combustion calorific value, reduce the emission of harmful substances such as carbon monoxide and hydrogen hydroxide, improve the utilization efficiency of the gas, and achieve energy-saving and environmental protection effects.

[0017] As a further solution of the present invention, the diameter of the tiny gas exhaust port in household gas equipment is 1.0 mm to 2.0 mm, and the diameter in commercial gas equipment is 1.3 mm to 2.5 mm, so as to adapt to the combustion requirements of different application scenarios.

[0018] As a further solution of the present invention, the efficient and energy-saving gas complete combustion method is suitable for application scenarios including but not limited to gas stoves, water heaters, heaters, combustion furnaces, gas ovens, and large gas heating equipment.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. Energy saving and environmental protection: By precisely controlling the gas flow and ensuring heat through secondary combustion and optical reflection, the combustion efficiency is significantly improved, so that the gas can be completely burned compared to existing technologies. The reduced gas consumption not only saves energy, but also reduces carbon emissions, which is of great significance to environmental protection.

[0021] 2. Complete combustion: The secondary combustion technology is introduced to re-burn the incompletely burned gas through the concentrated fire burner to ensure that the gas is completely burned at a high temperature of 800 to 1000 degrees. This process not only maximizes the release of combustion heat, but also effectively eliminates harmful substances such as carbon monoxide and hydroxide, avoiding poisoning and skin damage caused by incomplete combustion, and improving safety of use.

[0022] 3. Improved thermal efficiency: The concentrated fire burner is based on the principle of light reflection. It focuses the flame and heat to the bottom of the pot through the reflective surface, realizing the centralized utilization of flame and heat. This design not only improves the thermal efficiency of the burner, but also avoids heat loss and local overheating, making the pot heated evenly and achieving better cooking effect.

[0023] 4. Structural optimization: The traditional pot support is innovatively cancelled, and the fire-gathering burner is used as a support, which simplifies the external structure of the gas cooker and increases the stability and aesthetics of the equipment. At the same time, the flame size and gas flow are controlled by the electronic igniter, achieving precise combustion control, further improving the convenience and safety of the equipment.

[0024] 5. Wide application: This method is not only applicable to household gas appliances, such as gas stoves, water heaters and heaters, but also to commercial gas appliances, such as combustion furnaces, gas ovens and large gas heating equipment. Its wide applicability enables this technology to significantly improve combustion efficiency and energy saving in a variety of application scenarios.

[0025] 6. Reduce harmful emissions: Through complete combustion and secondary combustion technology, the present invention significantly reduces the emission of carbon monoxide and other harmful substances, and improves the environmental performance of the equipment. This improvement not only complies with environmental regulations and standards, but also has important significance for improving the living environment and health conditions of users.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] See also Figure 1 In an embodiment of the present invention, a highly efficient and energy-saving gas complete combustion method comprises the following steps:

[0031] Step 1, the gas is initially burned through a tiny gas discharge port, the diameter of the tiny gas discharge port is 1.0 mm to 2.5 mm, the gas is delivered to the gas discharge port through a gas delivery pipeline, and the diameter of the gas discharge port is smaller than the diameter of the gas discharge port of the traditional atmospheric combustion method, so as to achieve precise control of the gas flow rate;

[0032] Step 2: During the initial combustion process, the gas is ignited by an electronic igniter, and the gas flow rate and flame size are controlled by the electronic igniter to ensure that the gas reaches the required combustion temperature and combustion efficiency during the initial combustion;

[0033] Step 3, during the initial combustion process, the incompletely burned gas flow is discharged to a focus burner, wherein the focus burner includes a reflective surface whose back is invisible, and based on the principle of light reflection, the incompletely burned gas flow is reflected and focused to the bottom of the pot to achieve high-temperature and efficient combustion;

[0034] Step 4, the fire-focusing burner performs secondary combustion on the incompletely burned gas flow. During the secondary combustion process, the combustion temperature is controlled between 800 and 1000 degrees to ensure complete combustion of the gas;

[0035] Step 5: During the secondary combustion process, the flame and heat are concentrated to the bottom of the pot through the light reflection and focusing function of the fire-focusing burner, so as to achieve uniform heating while avoiding excessive local temperature and ensuring uniform heating of the pot;

[0036] Ultimately, the above steps can achieve complete combustion of the gas, maximize the release of combustion calorific value, reduce the emission of harmful substances such as carbon monoxide and hydrogen hydroxide, improve the utilization efficiency of the gas, and achieve energy-saving and environmental protection effects.

[0037] The diameter of the tiny gas discharge port in household gas equipment is 1.0mm to 2.0mm, and the diameter in commercial gas equipment is 1.3mm to 2.5mm, to meet the combustion requirements of different application scenarios. In addition, the efficient and energy-saving gas complete combustion method is suitable for application scenarios including but not limited to gas stoves, water heaters, heaters, burners, gas ovens, and large gas heating equipment.

[0038] The shape of the fire-focusing burner is a concave structure, and a smooth curved reflective surface is formed on the back thereof. The reflective surface is designed to accurately focus the flame and the incompletely burned gas flow to a specified area, such as the bottom of a pot or the surface of a heat exchanger, during the secondary combustion process. Since the reflective surface is located on the back of the burner, it is usually not directly observable, but the curved surface design of the concave inner wall ensures the efficient realization of the reflection and focusing functions, thereby maximizing the combustion efficiency and thermal energy utilization of the gas, which are all extended implementation methods known to ordinary technicians in the field.

[0039] Embodiment 1:

[0040] In the catering industry, gas stoves are used very frequently. Traditional atmospheric gas stoves, due to incomplete combustion, lead to a large amount of gas waste and harmful substances emission, which seriously affects energy utilization efficiency and environmental quality. In order to solve this problem, the efficient and energy-saving gas complete combustion method provided by the present invention is used to transform the gas stoves in the catering industry.

[0041] The specific implementation steps are as follows:

[0042] First, the gas discharge structure of traditional gas cookers was modified, and the original atmospheric gas discharge port with a diameter of 3mm to 5mm was changed to a tiny gas discharge port with a diameter of 1.0mm to 2.0mm. This modification enables the gas flow to be precisely controlled, thus ensuring a more stable and efficient gas supply during the initial combustion process.

[0043] During the initial combustion process, an electronic igniter is used to ignite the gas discharged through the tiny gas discharge port. The electronic igniter can not only quickly ignite the gas, but also adjust the size of the flame and the gas flow rate according to actual needs to ensure that the gas reaches a high temperature of 800 to 1000 degrees during the initial combustion to achieve full combustion.

[0044] Next, the incompletely burned gas flow is directed to the focus burner. The focus burner is designed based on the principle of light reflection. Its back contains an invisible reflective surface that can focus the incompletely burned gas to the bottom of the pot for secondary combustion. In this process, the focus burner concentrates the flame and heat to the bottom of the pot, further improving the combustion efficiency and heat utilization. The temperature of the secondary combustion is also controlled between 800 and 1000 degrees to ensure thorough combustion and minimize the emission of harmful substances such as carbon monoxide and hydrogen hydroxide.

[0045] Due to the light reflection and focusing function of the concentrated fire burner, the flame and heat are evenly distributed on the bottom of the pot, avoiding the problem of flame and heat dispersion in traditional gas cookers, thereby improving cooking efficiency and effect. The traditional pot support is eliminated and replaced with a concentrated fire burner support, which not only simplifies the external structure of the gas cooker, but also increases the stability and aesthetics of the equipment.

[0046] The actual application results show that the gas utilization rate of the gas cooker after the above transformation has been significantly improved. Compared with the traditional atmospheric gas cooker, the gas consumption has been reduced by about 50%, and the combustion efficiency has been improved to a complete combustion state. At the same time, the emission of carbon monoxide and other harmful substances has been significantly reduced, meeting more stringent environmental protection standards and improving the kitchen environment and the health conditions of operators.

[0047] Through this specific embodiment, the practical application effect of the present invention in the catering industry is fully demonstrated. It not only solves the problems of incomplete combustion, energy waste and high emission of harmful substances in traditional atmospheric gas stoves, but also achieves significant energy-saving and environmental protection benefits, reflecting the innovativeness and practical value of the technical solution of the present invention.

[0048] Embodiment 2:

[0049] In household use, traditional gas water heaters have problems with incomplete combustion, harmful substances are emitted in the relatively closed environment of the bathroom, and there are relatively large safety hazards and energy waste. In particular, the diameter of the gas discharge port of traditional atmospheric gas water heaters is large, usually 3mm to 5mm, and the combustion efficiency is low, which easily leads to the production of harmful substances such as carbon monoxide, threatening the health of users.

[0050] The specific implementation steps are as follows:

[0051] The gas discharge structure of the traditional gas water heater is modified, and the original atmospheric gas discharge port with a diameter of 3mm to 5mm is changed to a tiny gas discharge port with a diameter of 1.0mm to 2.0mm. This modification enables the gas flow to be precisely controlled, thereby ensuring that the gas supply during the initial combustion process is more stable, efficient and conducive to full combustion.

[0052] During the initial combustion process, an electronic igniter is used to ignite the gas discharged through the tiny gas discharge port. The electronic igniter can not only quickly ignite the gas, but also adjust the size of the flame and the gas flow rate according to actual needs to ensure that the gas reaches a high temperature of 800 to 1000 degrees during the initial combustion to achieve full combustion.

[0053] Next, the incompletely burned gas flow is directed to the focus burner. The focus burner is designed based on the principle of light reflection. Its back contains an invisible reflective surface that can focus the incompletely burned gas on the heat exchanger of the water heater for secondary combustion. In this process, the focus burner concentrates the flame and heat on the heat exchanger, further improving the combustion efficiency and heat utilization. The temperature of the secondary combustion is also controlled between 800 and 1000 degrees to ensure thorough combustion and minimize the emission of harmful substances such as carbon monoxide and hydroxide.

[0054] Due to the light reflection and focusing function of the concentrated fire burner, the flame and heat are evenly distributed on the heat exchanger, avoiding the problem of flame and heat dispersion in traditional gas water heaters, thereby improving the heating efficiency and effect. At the same time, the unnecessary heat exchange bracket inside the traditional water heater is eliminated and replaced with a concentrated fire burner support, which not only simplifies the internal structure of the water heater, but also increases the stability and aesthetics of the equipment.

[0055] The actual application results show that the gas utilization rate of the gas water heater after the above transformation has been significantly improved. Compared with the traditional atmospheric gas water heater, the gas consumption has been reduced by about 50%, and the combustion efficiency has been improved to a complete combustion state. At the same time, the emission of carbon monoxide and other harmful substances has been significantly reduced, meeting more stringent environmental protection standards and improving the family environment and the health conditions of users.

[0056] Example 2: For example, efficient transformation and application of household gas water heaters.

[0057] In traditional household use, gas water heaters usually use atmospheric combustion, which has problems such as incomplete combustion, low thermal efficiency, and high emission of harmful substances. These problems are more serious in closed environments (such as bathrooms), leading to safety hazards and energy waste. In particular, the diameter of the gas discharge port of traditional atmospheric gas water heaters is large, usually 3mm to 5mm, making it difficult to achieve precise combustion control. Therefore, an efficient and energy-saving transformation plan is needed to improve combustion efficiency, reduce harmful substance emissions, and ensure user safety.

[0058] The specific implementation steps are:

[0059] 1. Accurate modification of the gas discharge structure: The diameter of the gas discharge port of the traditional gas water heater is changed from 3mm to 5mm to a small diameter discharge port of 1.0mm to 2.0mm. This significantly reduces the gas flow rate, making the gas supply more stable and more conducive to full combustion.

[0060] 2. During the initial combustion stage, the gas is ignited by an electronic igniter, and the flame size and gas flow rate are precisely controlled by the electronic igniter to ensure that the gas reaches a high temperature of 800 to 1000 degrees during the initial combustion to achieve full combustion.

[0061] 3. Introducing a secondary combustion device: The incompletely burned gas after the initial combustion is directly guided to a dedicated fire-focusing burner for secondary combustion through a specially designed gas guide pipe. The fire-focusing burner includes a reflective surface (invisible) located on the back, which uses the principle of light reflection to accurately focus the incompletely burned gas onto the heat exchanger surface of the water heater.

[0062] 4. During the secondary combustion process, the temperature is maintained between 800 and 1000 degrees to ensure that all incompletely burned gas is completely burned. Through the secondary combustion technology, not only can the remaining gas be completely burned, but also the emission of harmful substances such as carbon monoxide and hydrogen hydroxide can be significantly reduced.

[0063] 5. Application of light reflection and focusing technology: The reflection surface of the concentrated fire burner is designed as a high-precision smooth arc surface, and its concave design can focus the burning flame and heat on the heat exchanger. This design ensures the centralized use of heat, avoids the problem of flame and heat dispersion in traditional gas water heaters, and thus improves combustion efficiency. This reflection and focusing technology makes the heat exchanger surface more evenly heated, avoids the problem of local over-temperature, and improves the uniformity and overall efficiency of hot water heating.

[0064] 6. Structural optimization and equipment improvement: The unnecessary heat exchange bracket inside the traditional water heater is eliminated and replaced with a concentrated fire burner support. This transformation not only simplifies the equipment structure, but also increases the stability and aesthetics of the equipment and reduces the overall maintenance cost. Through the improved structural design, the energy efficiency of the water heater is significantly improved, and the gas consumption is reduced by 50% compared with traditional water heaters, and the combustion efficiency reaches the level of complete combustion.

[0065] After the above transformation, the household gas water heater has significantly improved the gas utilization rate, reduced gas consumption, and complies with stricter environmental protection and safety standards. Through thorough secondary combustion and light reflection and focusing functions, the emission of carbon monoxide and other harmful substances has been significantly reduced, effectively improving the home environment and the health conditions of users.

[0066] Compared with the prior art, this embodiment not only demonstrates the accuracy of gas flow control and thorough secondary combustion technology, but also combines the efficient use of optical reflection to comprehensively improve the thermal efficiency of gas combustion and significantly reduce the emission of harmful substances. These innovations solve the problems of incomplete combustion and high safety hazards in traditional water heaters.

[0067] Example 3: Application of industrial ovens in paint spraying plants and hardware spraying plants.

[0068] In industrial scenarios such as paint plants and hardware spray plants that require large-area heating, traditional industrial ovens have the disadvantages of wasting gas, incomplete combustion, and emitting a large amount of harmful gases due to their huge size and large number of burners. Especially in the closed high-temperature environment of such ovens, high-power exhaust fans are usually required to exhaust harmful gases produced by incomplete combustion. However, this method not only consumes a lot of energy, but also increases equipment maintenance and operating costs.

[0069] The efficient and energy-saving gas complete combustion method provided by the present invention significantly improves the utilization rate of gas, reduces the emission of harmful substances, eliminates the dependence on high-power exhaust fans, and significantly improves energy-saving and environmental protection performance by modifying the combustion device of a traditional industrial oven.

[0070] The specific implementation steps are as follows:

[0071] 1. Gas emission structure modification: In traditional industrial ovens, there are many burners, and two rows of burners are installed on the bottom and middle parts for heating. The diameter of the gas emission port is usually large (3mm to 5mm in diameter), resulting in low combustion efficiency. In order to improve the gas utilization efficiency, the gas emission structure of the burner is modified, and the diameter of the traditional atmospheric gas emission port is reduced to 1.3mm to 2.5mm. This modification enables the gas flow to be precisely controlled, ensuring that the gas can reach the best combustion state in each burner.

[0072] 2. Initial combustion process: The modified gas discharge port makes the gas supply more stable, and the initial combustion process is completed by the electronic igniter. The electronic igniter can not only quickly ignite the gas, but also accurately control the flame size and gas flow rate to ensure that the gas reaches a high temperature of 800 to 1000 degrees during the initial combustion process. This can significantly improve the combustion efficiency and reduce the generation of harmful gases caused by incomplete combustion.

[0073] 3. Secondary combustion process and application of fire-focusing burner: During the primary combustion process, the incompletely burned gas flow is guided to the fire-focusing burner inside the industrial oven. The fire-focusing burner consists of multiple tiny gas discharge ports and is designed with a smooth reflective surface on the back, which can focus the incompletely burned gas to a designated area for secondary combustion.

[0074] During the secondary combustion process, the combustion temperature is controlled between 800 and 1000 degrees to ensure that all incompletely burned gases are completely burned. Compared with traditional gas systems, secondary combustion can not only reduce the emission of harmful gases such as carbon monoxide and hydrogen hydroxide, but also improve the utilization rate of thermal energy and make the heat in the oven more evenly distributed.

[0075] 4. Heat concentration and uniform heating: The burners of industrial ovens are usually arranged at the bottom and in the middle. The modified fire-focusing burner focuses the flame and heat on the product channel area of ​​the oven through its reflective surface design. Through precise heat focusing, the heat distribution inside the entire oven is more uniform, avoiding the problems of heat dispersion and local over-high or over-low temperatures in traditional ovens, and improving the consistency and quality of product heating.

[0076] 5. Eliminate high-power exhaust fans: Improve energy efficiency. Traditional industrial ovens often rely on high-power exhaust fans to discharge harmful gases due to incomplete combustion. However, after applying the technical solution of the present invention, the thorough combustion effect of secondary combustion and precise gas flow control greatly reduce the emission of harmful substances caused by incomplete combustion. This not only eliminates the need for high-power exhaust fans, reduces energy consumption, but also reduces the operation and maintenance costs of the equipment.

[0077] 6. Practical application effect: The gas utilization rate of the industrial oven after the above transformation has been significantly improved. Compared with the traditional oven, the gas consumption has been reduced by about 50%. The combustion efficiency has been improved, and the emission of harmful gases such as carbon monoxide has been significantly reduced, meeting more stringent environmental protection standards. The heat distribution in the oven is more uniform, and the product heating effect is more consistent, ensuring the quality stability of the baked products. At the same time, the elimination of high-power exhaust fans not only simplifies the equipment structure, but also further improves the reliability and economic benefits of the equipment.

[0078] Through the application of the technology of the present invention, the industrial oven has been significantly improved in terms of gas utilization efficiency, combustion completeness, and heat uniformity. At the same time, the combination of secondary combustion technology and light reflection and focusing function not only improves the complete combustion efficiency of gas, but also reduces the emission of harmful gases and reduces the dependence on high-power exhaust equipment, achieving energy-saving, environmental protection, safety and reliability.

[0079] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
