Description

Technical Field

[0001] The present disclosure relates to the technical field of glass kilns, and in particular to a kiln firing gun device and a glass kiln system. Background Art

[0002] After the melting tank of a glass kiln is built, the temperature must be gradually raised and baked from room temperature to approximately 800-850°C. Once the temperature reaches 850°C, the kiln is switched to a primary burner, such as oxyfuel. The kiln bake-in process is crucial, requiring a steady temperature increase rate. Certain temperature points must be held for a certain period of time, and the temperature must not fluctuate significantly during this period.

[0040] Example 1

[0041] like Figure 1 and Figure 2 As shown, a kiln baking gun device includes a feed pipe 1, an inner gun barrel 2, a gun head 4 and an outer gun barrel 5. The feed pipe 1 is used to transport a mixture of fuel and combustion-supporting air. The inner gun barrel 2 is connected to the feed pipe 1. An igniter 3 is provided in the inner gun barrel 2. The gun head 4 is connected to the inner gun barrel 2. The outer gun barrel 5 is provided on the outside of the inner gun barrel 2. An air inlet is provided on the outer gun barrel 5. The outer gun barrel 5 is connected to the gun head 4.

[0042] The fuel pipe 1 is a conduit connecting the external environment to the interior of the equipment. Its primary function is to guide the mixture of fuel and combustion air into the equipment. Specifically, the fuel pipe 1 can be a metal pipe, suitable for high-temperature, high-pressure environments. Alternatively, the fuel pipe 1 can be a heat-resistant composite material, lightweight and low-cost. More specifically, the fuel pipe 1 can be a straight pipe: simple and direct, with low resistance, suitable for applications with high flow rates and requiring fast response. The fuel pipe 1 can also be a curved pipe, capable of being bent according to actual layout requirements, suitable for applications with limited space. The fuel pipe 1 can also be a Venturi tube, utilizing the Venturi effect to accelerate fluid flow and suitable for applications requiring precise flow rate control. More specifically, the fuel pipe 1 can be a pressurized fuel pipe, connected to a turbocharger or supercharger to increase gas pressure and improve combustion efficiency. The fuel pipe 1 can also be a premixing pipe, mixing the gas with the fuel before entering the combustion zone for better combustion.

[0043] More specifically, a valve 7 is installed on the feed pipe 1 to regulate the material flow. Valve 7 consists of a handwheel switch assembly made of pure copper and a screw with a zinc-plated surface. The operator can adjust valve 7 to control the supply of fuel and combustion air, allowing the fuel and combustion air to pre-combust in the inner barrel 2 before undergoing a secondary combustion within the main burner. The heat generated by the pre-combustion and secondary combustion is then transported into the kiln, where it circulates and is discharged.

[0044] Natural gas can be used as the fuel, offering clean combustion efficiency, ease of regulation, and environmentally friendly combustion products. It is suitable for most industrial furnaces, particularly those requiring high combustion temperatures and environmental conditions. Alternatively, liquefied petroleum gas (LPG) offers high combustion efficiency, high flame temperatures, and ease of storage and transportation, making it suitable for small and medium-sized furnaces, particularly those requiring highly flexible regulation. Alternatively, heavy oil offers high energy density and low cost. However, the combustion process may produce significant amounts of smoke and pollutants, requiring regular burner maintenance, making it suitable for large industrial furnaces, particularly those where fuel costs are a concern.

[0045] Combustion-supporting wind refers to the air or oxygen source used to support fuel combustion, and its quality and flow rate directly affect combustion efficiency and temperature control. Specifically, combustion-supporting wind can be natural ventilation, relying on natural airflow to provide combustion-supporting wind, which is suitable for small or low-power kilns, and is suitable for small ceramic kilns, experimental kilns, etc. Combustion-supporting wind can also be forced ventilation, using a blower or fan to actively provide combustion-supporting wind, and the air volume and wind pressure can be accurately controlled. Combustion-supporting wind can be oxygen-enriched wind, using pure oxygen or high-concentration oxygen to replace part or all of the air, thereby improving combustion efficiency and reducing the generation of nitrogen oxides. For example, the feed pipe 1 can be connected to an oxygen generator, an oxygen storage tank, etc. to provide oxygen-enriched wind, with high combustion temperature, high combustion efficiency, and low pollutant emissions.

[0046] The inner barrel 2 refers to the pipe located inside the kiln gun device, primarily used to transport the mixture of fuel and combustion air. It is connected to the igniter 3 to ensure that the mixture is effectively ignited when it reaches the combustion zone. Specifically, the inner barrel 2 can be a straight tube, with a simple structure and low resistance, suitable for applications requiring linear transport of fuel and combustion air. The inner barrel 2 can also be tapered, gradually tapering from one end, to increase the flow rate of the mixture, improve combustion efficiency, help form a stable flame, and reduce uneven combustion, suitable for applications requiring high combustion efficiency and precise temperature control. The inner barrel 2 can also be multi-channel, with multiple independent channels inside the inner barrel 2, which can separately transport different types of fuel and combustion air. This allows for more complex mixing and combustion control, improves combustion efficiency, and is suitable for advanced kiln gun devices that require the mixed combustion of multiple fuels. More specifically, the inner barrel 2 can be a metal inner barrel 2, such as stainless steel or heat-resistant alloys, which are resistant to high temperatures, corrosion, and wear, suitable for high temperatures and harsh environments, and suitable for most industrial kilns and high-temperature heating equipment. The inner barrel 2 can also be made of a refractory ceramic material that is resistant to high temperatures and corrosion, suitable for special applications requiring extremely high heat resistance. The inner barrel 2 can also be a composite material inner barrel 2, composed of a composite material such as metal and ceramic, metal and heat-resistant plastic, etc., combining the advantages of multiple materials to have excellent high temperature resistance, corrosion resistance, and wear resistance.

[0047] More specifically, a cooling channel is provided inside or outside the inner barrel 2, which can reduce the temperature of the inner barrel 2 by water cooling or air cooling, etc., which can effectively extend the service life of the inner barrel 2, improve the reliability and safety of the equipment, and is suitable for kiln gun devices that operate at high temperatures for a long time.

[0048] The igniter 3 refers to a device installed in the inner barrel 2 of the kiln gun, which is used to ignite the mixture of fuel and combustion-supporting air ejected from the inner barrel 2. Specifically, the igniter 3 can be an electric spark igniter 3, which ignites the mixture through high-voltage electric sparks, with fast ignition speed, high reliability and simple operation. It is suitable for most kiln gun devices, especially occasions where rapid ignition is required. The igniter 3 can also be a hot wire igniter 3, which heats the resistance wire to a high temperature and then ignites the mixture, and is suitable for occasions where frequent ignition is not required. The igniter 3 can also be an infrared igniter 3, which heats the mixture through infrared radiation to reach the ignition temperature, including an infrared radiation source, a reflector and thermal insulation materials, and has uniform ignition and a stable flame. The igniter 3 can also be an ultrasonic igniter 3, which activates the fuel molecules in the mixture through ultrasonic vibrations, making it easier to ignite. It includes an ultrasonic generator, a transducer and a resonance cavity, has high ignition efficiency and is suitable for low-volatility fuels.

[0049] Gun head 4 refers to the part located at the front end of the kiln gun, is connected to the inner barrel 2, and is responsible for ejecting and igniting the mixture of fuel and combustion-supporting air. Gun head 4 can be a direct injection type, with one or more direct injection holes at the front end of gun head 4, and the mixture ejects in a straight line direction, which has a simple structure and low manufacturing cost, and is applicable to occasions where concentrated flames and a smaller combustion area are needed. Gun head 4 can also be a diffusion type, with a plurality of diffusion holes at the front end of gun head 4, and the mixture ejects in a fan-shaped or conical shape, which can cover a larger combustion area and improve combustion uniformity, and is applicable to occasions where uniform heating and a larger combustion area are needed. Gun head 4 can also be a swirl type, with a swirl blade or a spiral groove designed inside gun head 4, so that the mixture forms a swirl when ejected, so as to improve the turbulence degree of the mixture, promote the full mixing of fuel and combustion-supporting air, and improve combustion efficiency. Gun head 4 can also be a porous type, with a plurality of small holes at the front end of gun head 4, and each small hole can spray the mixture separately, which can achieve more refined combustion control and improve combustion uniformity and stability.

[0050] The outer barrel 5 is a pipe that fits over the outer surface of the inner barrel 2 and connects to the gun head 4. It is used to introduce additional combustion air to optimize the mixing of fuel and combustion air and improve combustion efficiency. The outer barrel 5 includes a main pipe, air inlets, and a connection interface. The main pipe is made of high-temperature resistant materials such as stainless steel, heat-resistant alloys, or refractory ceramics. The main pipe can be straight, curved, or tapered, with the specific shape designed according to the equipment layout and combustion requirements. Air inlets are distributed on the sides or ends of the outer barrel 5 to ensure that the combustion air can enter the combustion area evenly. The number and size of the air inlets are determined according to the combustion requirements and equipment specifications, and generally require optimized design through testing and calculations. The outer barrel 5 can be provided with adjustable air inlets, and the air intake can be adjusted via valve 7 or baffles to adapt to different combustion conditions. The connection between the connector and the gun head 4 ensures a secure connection between the outer barrel 5 and the gun head 4, ensuring that the combustion air can enter the combustion area smoothly. The outer barrel 5 can also be provided with a cooling channel, which can be used to reduce the temperature of the outer barrel 5 through water cooling or air cooling to extend its service life. Common cooling media include water, air or cooling oil.

[0051] The inner barrel 2 and outer barrel 5 can be threaded together. The connecting ends of the inner barrel 2 and outer barrel 5 are respectively processed into internal and external threads, and the connection is achieved by tightening the threads. Installation and disassembly are convenient, and the connection is reliable. Threaded connections require additional sealing measures, such as sealing washers or sealant. This is suitable for situations where frequent assembly and disassembly are required. The inner barrel 2 and outer barrel 5 can also be flanged together. The connecting ends of the inner barrel 2 and outer barrel 5 are respectively processed into flanges and fixed together with bolts and nuts. This provides high connection strength and good sealing, and is suitable for high-pressure and high-temperature environments. The inner barrel 2 and outer barrel 5 can also be welded together. The connecting ends of the inner barrel 2 and outer barrel 5 are fixed together by welding. This provides high connection strength, good sealing, and a permanent connection, suitable for fixed installation situations where disassembly is not required. The inner barrel 2 and outer barrel 5 can also be connected by a ferrule. The inner barrel 2 is inserted into the connecting end of the outer barrel 5 and fixed with a ferrule and nut. This provides easy installation, a reliable connection, and good sealing. It is suitable for small and medium-caliber kiln gun devices. The inner barrel 2 and the outer barrel 5 can also be connected by quick plugging. The connecting end of the inner barrel 2 and the outer barrel 5 is designed as a quick plug connector, which can be connected and disconnected by a simple plug-in and pull-out action. It is very convenient to install and disassemble, and is suitable for occasions where quick replacement is required.

[0052] A gap is provided between the inner barrel 2 and the outer barrel 5, and the air inlet is connected to the gap. The combustion-supporting air introduced through the air inlet on the outer barrel 5 can be evenly distributed through the gap into the mixture surrounding the inner barrel 2, improving the uniformity and stability of combustion. The combustion-supporting air in the gap also provides a certain cooling effect, protecting the inner barrel 2 and igniter 3 from high temperature damage, and extending the service life of the equipment. The even distribution of the combustion-supporting air helps form a more stable flame, reducing incomplete combustion and localized overheating.

[0053] The gap size should be determined based on specific combustion requirements and equipment specifications. It should not be too large or too small. A gap that is too large may result in excessive combustion airflow, affecting combustion efficiency and even causing flame instability. A gap that is too small may restrict the flow of combustion air, affecting combustion performance. Specifically, the gap size should be between 1 and 5 mm.

[0054] Through the above technical solution, the kiln baking gun device provided by the present invention puts a mixture of natural gas and combustion-supporting air into the inner barrel 2, and ignites the mixture in the inner barrel 2 through an igniter to achieve initial combustion, and the subsequent mixed gas enters the muzzle, and the secondary combustion-supporting air enters the main combustion chamber through the outer tube, and is further mixed with the mixed gas after pre-combustion, thereby improving combustion efficiency, promoting complete combustion, and helping to maintain a stable combustion process, which can remain stable even when the fuel properties or operating conditions change, thereby improving the uniformity and stability of fuel combustion, and effectively ensuring the stability of kiln temperature rise.

[0055] In some embodiments, a plurality of fins are fixedly connected between the inner barrel 2 and the outer barrel 5. The fins are arranged along the circumference of the inner barrel 2 and are evenly distributed along the extension direction of the inner barrel 2. The fins are provided with vents, and air entering through the air inlet can enter the gun head 4 through the multiple vents. Specifically, the fins can be flat or curved and arranged along the circumference of the inner barrel 2. Depending on the combustion requirements and equipment specifications, the number of fins can range from a few to dozens. The shape of the vents can be circular, oval, or elongated, and the specific shape and size are determined by the flow rate and pressure of the combustion-supporting air.

[0056] Specifically, the air inlet can be provided on an end plate at the end of the outer barrel 5 away from the gun head 4, and enter the gun head 4 through a plurality of air vents. More specifically, the air inlet can be symmetrically distributed on both sides of the end plate. The air vents on the fins can further disperse the combustion-supporting air entering through the air inlet, so that it is more evenly distributed in the mixture around the inner barrel 2, thereby improving the uniformity and stability of combustion. The cooling effect fins increase the contact area between the outer barrel 5 and the inner barrel 2, helping to remove more heat through the combustion-supporting air, and protecting the inner barrel 2 and the igniter 3 from high temperature damage. The fins can enhance the connection strength between the inner barrel 2 and the outer barrel 5, and improve the stability of the overall structure.

[0057] The combustion-supporting air enters the gap between the outer barrel 5 and the inner barrel 2 through the air inlet holes in the outer barrel 5. After entering the gap, the combustion-supporting air is further dispersed through the air vents in the fins and evenly distributed in the mixture around the inner barrel 2. The uniform distribution of the combustion-supporting air helps to form a more stable flame, improving combustion efficiency and the stability of temperature control. By adjusting the flow rate of the air inlet holes, the combustion conditions can be further optimized to meet different combustion requirements. The fins increase the contact area between the outer barrel 5 and the inner barrel 2, allowing the combustion-supporting air to carry away more heat, protecting the inner barrel 2 and the igniter 3 from high-temperature damage.

[0058] In some embodiments, a plurality of fins are provided on the inner wall of the inner barrel 2, and the fins are arranged along the extension direction of the inner barrel 2, and the plurality of fins are evenly distributed along the circumference of the inner barrel 2. Specifically, the fins are flat or arc-shaped. Depending on the combustion requirements and equipment specifications, the number of fins can vary from a few to dozens. The height and width of the fins need to be determined based on the diameter of the inner barrel 2 and the combustion requirements, and the height is between a few millimeters and more than ten millimeters. The fins can increase the turbulence of the fuel and combustion-supporting air in the inner barrel 2, promote more complete mixing of the two, and improve combustion efficiency. The presence of the fins can make the mixture more uniform when entering the combustion area, help form a stable flame, and reduce uneven combustion and local overheating. The fins can enhance the rigidity of the inner barrel 2 and improve the stability of the overall structure.

[0059] In some embodiments, the inner barrel 2 includes a tube body 21 and a combustion section 22. The first end of the tube body 21 is connected to the gun head 4, the second end of the tube body 21 is connected to the combustion section 22, the combustion section 22 is connected to the feed pipe 1, and the igniter 3 is arranged in the combustion section 22. The tube body 21 is the main part of the inner barrel 2, and is used to transport a mixture of fuel and combustion-supporting air. The first end of the tube body 21 is connected to the gun head 4 to ensure that the mixture can be smoothly ejected and ignited. The tube body 21 is made of high-temperature resistant materials, such as stainless steel, heat-resistant alloys, etc. The tube body 21 can be straight, curved or conical, and the specific shape is designed according to the equipment layout and combustion requirements. The combustion section 22 is a part of the inner barrel 2, which is specifically used to optimize the mixing of fuel and combustion-supporting air to ensure that the mixture can be quickly ignited and stably burned when entering the combustion area. Ribs and swirl blades can be set inside the combustion section 22 to improve the mixing effect and combustion efficiency. More specifically, as Figure 3 As shown, the tube body 21 and the combustion part 22 can be connected through an inner tube joint 221 , and the outer barrel 5 is connected to the outer tube joint 222 .

[0060] The mixture of fuel and combustion-supporting air enters the combustion section 22 through the feed pipe 1. Inside the combustion section 22, fins, swirl vanes, and other structures create turbulence, further optimizing the mixing effect. The optimized mixture in the combustion section 22 is then transported to the lance tip 4 through the pipe body 21. Fins or other structures are designed inside the pipe body 21 to further enhance the uniform distribution of the mixture. The mixture is ejected through the lance tip 4 and mixed with the combustion-supporting air introduced by the outer barrel 5. As the mixture approaches the outlet of the combustion section 22, it is rapidly ignited by the igniter 3.

[0061] In some embodiments, the combustion portion 22 gradually shrinks from the side close to the feed pipe 1 to the side away from the feed pipe 1. Specifically, the combustion portion 22 can gradually shrink from the side close to the feed pipe 1 to the side away from the feed pipe 1 to form a cone or trumpet shape. The cross-sectional area of ​​the combustion portion 22 gradually decreases from large to small, and can change linearly or nonlinearly. The length of the combustion portion 22 is determined according to the combustion requirements and equipment specifications, and can be between a few centimeters and tens of centimeters. The combustion portion 22 is made of high-temperature resistant materials such as stainless steel and heat-resistant alloys to ensure that the combustion portion 22 is not deformed or damaged in a high-temperature environment. The combustion portion 22 can also be subjected to anti-corrosion treatment, and corrosion-resistant and wear-resistant materials can be selected to ensure the long-term stable operation of the equipment.

[0062] In some embodiments, a mixer is also included, which is connected to the feed pipe 1. The mixer is connected to a first pipe and a second pipe, and the first pipe and the second pipe are used to transport the auxiliary fuel and the combustion-supporting air respectively. The mixer is a device specifically used to mix the auxiliary fuel and the combustion-supporting air, and is a chamber or a pipe. The mixer is connected to the feed pipe 1 to ensure that the mixed gas can smoothly enter the combustion part 22. The mixer and its connecting pipes are made of high-temperature resistant materials such as stainless steel and heat-resistant alloys to ensure that they are not deformed or damaged in high-temperature environments. The mixer can also be treated with anti-corrosion, and corrosion-resistant and wear-resistant materials can be selected to ensure the long-term stable operation of the equipment. Specifically, the mixer is provided with mixing elements such as spiral blades, inclined plates, etc. to ensure that the auxiliary fuel and the combustion-supporting air can be fully mixed. Welding, threaded connection or flange connection can be used between the mixer and the feed pipe 1, the first pipe and the second pipe. The connection parts can also be sealed to prevent leakage of the mixture.

[0063] In some embodiments, the outlet end of the gun head 4 is provided with a plurality of air outlet holes, and the plurality of air outlet holes are arranged in a circular array. The gun head 4 is the front end part of the kiln gun device, which is responsible for spraying and igniting the mixed fuel and combustion air. The outlet end of the gun head 4 is provided with a plurality of air outlet holes, and these air outlet holes are arranged in a circular array. The shape of the air outlet hole can be circular, elliptical or long, and the specific shape and number are determined according to the combustion requirements and equipment specifications. The air outlet holes can be designed with different injection angles to adapt to different combustion requirements. The air outlet holes are arranged in a circular array to ensure that the mixture can be sprayed evenly, further optimize the distribution of fuel and combustion air, improve combustion efficiency and flame stability, and avoid the flame being too long and burning the kiln body bricks.

[0064] In some embodiments, the device further includes a flameout protection device 6, which is disposed on the feed pipe 1. The flameout protection device 6 is used to detect the combustion state and automatically cut off the fuel supply when flameout is detected to prevent safety accidents. This design greatly improves the safety and reliability of the device. Specifically, the flameout protection device 6 includes a sensor, a controller, and a shut-off valve. The sensor is used to detect the combustion state, and sensor types include thermocouples, flame detectors, etc. The controller receives the signal from the sensor and controls the fuel supply based on the detection results. The shut-off valve is installed on the feed pipe 1 to cut off the fuel supply.

[0065] In some embodiments, the flameout protection device 6 includes a flameout detector 62 and a flameout valve 61. The flameout detector 62 is arranged near the gun head 4, and the flameout valve 61 is installed on the feed pipe 1. The flameout detector 62 and the flameout valve 61 are connected. Specifically, the flameout detector 62 is the above-mentioned sensor, and the sensor can be a thermocouple and a flame detector. Thermocouples are suitable for occasions where precise temperature control is required, with fast response speed and high accuracy. Flame detectors are suitable for occasions where direct detection of flame signals is required, with high sensitivity and rapid response. The controller can accurately process the sensor signal to avoid misjudgment. The controller can be equipped with an alarm function, and when a flameout is detected, an alarm is issued to alert the operator. The controller can be connected to a remote monitoring system to achieve real-time monitoring and remote control. The flameout valve 61 is a cut-off valve, which can have a manual or automatic reset function to facilitate recovery operations after troubleshooting.

[0066] Specifically, the flameout protection device 6 further includes a support frame 63 and a fixing platform. The support frame 63 is connected between the flameout detector 62 and the flameout valve 61 , and the fixing platform is connected to the gun head 4 or the outer barrel 5 to fix the flameout detector 62 .

[0067] The device also includes a leakage protector (R&D) and an overheating protector (OTP). These two devices are connected to the controller, forming a multi-layered safety mechanism to enhance overall safety. The R&D protector detects leakage in the circuit to prevent electric shock. It also detects overheating in the system to prevent equipment damage. The controller receives signals from various sensors, controls the operation of each protective device, and issues an alarm. More specifically, the R&D protector monitors leakage in the circuit in real time. When the R&D protector detects leakage, it transmits a signal to the controller via wires. Upon receiving the leakage signal, the controller immediately issues a command to cut off the power supply to prevent electric shock. Once the fault is resolved, the R&D protector must be reset manually or automatically to restore power. The O&D protector uses a temperature sensor to monitor the system temperature in real time. When the temperature exceeds a set value, the temperature sensor transmits a signal to the controller via wires. Upon receiving the overheat signal, the controller immediately issues a command to cut off the power supply or take other cooling measures. When the temperature returns to normal, the O&D protector must be reset manually or automatically to restore power.
