Description

Technical Field

[0001] This utility model relates to the field of burner technology, and specifically to a burner for uniformly heating products. Background Technology

[0002] A burner is a device that mixes fuel and air in a specific ratio, initiates a combustion reaction through an ignition device, and converts the chemical energy of the fuel into thermal energy. Its core function is to provide a stable and controllable flame and heat output, and it is widely used in industrial heating, power supply, and power engineering. Based on the principle of combustion, it controls the heat release rate and temperature by adjusting the fuel supply, air ratio, and combustion intensity. It is a key device in energy conversion and utilization systems, playing a crucial role in efficiently converting fuel energy into usable thermal energy.

[0003] Current burners suffer from uneven heating, localized overheating or underheating, disordered flue gas circulation leading to significant heat loss, and insufficient structural stability, which can affect heating performance. Additionally, the furnace body has poor high-temperature resistance and insulation, resulting in high energy consumption and susceptibility to damage from high temperatures. Utility Model Content

[0004] The purpose of this invention is to provide a burner that uniformly heats products, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a burner for uniformly heating products, including a furnace bottom, a furnace wall at the top of the furnace bottom, and a burner body extending transversely through the bottom of the four outer walls of the furnace wall;

[0006] A refractory frame is provided in the middle of the top of the furnace bottom, and a fire baffle is provided on the outside of the refractory frame;

[0007] A furnace door is hinged to the front outer wall of the furnace wall.

[0008] The beneficial effects of this utility model are as follows: the four burner bodies are symmetrically arranged on the four sides of the furnace wall, the flames act evenly on the fire baffle, guide the flue gas to form a stable circulation, improve the heating uniformity, the rectangular fire baffle makes the flue gas path regular, the height is lower than the refractory frame to avoid obstruction, and ensure that the flue gas fully contacts the product, the connecting legs of the refractory frame provide stable support, the placement frame is divided into sections to prevent stacking, the mesh plate is breathable to prevent uneven heating at the bottom, in the three-layer structure of the furnace wall, the steel plate shell ensures stability, the insulation layer reduces heat loss, and the refractory layer is resistant to high temperature, improving the durability of the equipment.

[0009] To achieve uniform flame distribution on the fire baffle from four directions by symmetrically positioning four burner bodies at the bottom of the front, rear, left, and right outer walls of the furnace, with the flame nozzles facing inwards and directly opposite the four sides of the fire baffle, thus avoiding concentrated or uneven flame distribution:

[0010] The burner body is further configured such that it is symmetrically located at the bottom of the outer wall of the furnace wall at the front, back, left, and right, with the flame nozzles facing inwards and directly opposite the four sides of the fire baffle wall.

[0011] By adopting the above technical solution, the four burner bodies are symmetrically arranged at the bottom of the front, rear, left, and right outer walls of the furnace, with the flame nozzles facing inwards and directly opposite the four sides of the fire baffle. This arrangement allows the flame to act evenly on the fire baffle from four directions, avoiding the situation of concentrated or unevenly distributed flames. This guides the flue gas generated by combustion to form a more stable and symmetrical circulation path, ensuring a balanced heat distribution in different areas of the furnace, effectively reducing the problem of insufficient or overheated local heating of products, and improving the uniformity and stability of heating.

[0012] To achieve a more regular and smooth flue gas circulation path by designing the firebreak wall as a rectangle with a height lower than the fire-resistant frame, reducing turbulence and dead zones in the flue gas flow, and avoiding obstruction:

[0013] The fire barrier is further configured such that it is rectangular and its height is lower than that of the fire-resistant frame.

[0014] By adopting the above technical solution, the fire barrier is rectangular and its height is lower than that of the fire-resistant frame. The rectangular structure makes the flue gas circulation path more regular and smooth, reduces the turbulence and dead corners in the flue gas flow process, and improves the circulation efficiency. The design of the fire barrier being lower than that of the fire-resistant frame can prevent the fire barrier from blocking the products on the fire-resistant frame and ensure that the flue gas can fully contact all parts of the products.

[0015] To provide stable support for the entire fire-resistant frame via connecting legs, the placement frames allow for zoned product placement, and the mesh panels enable heat and smoke to pass through and contact the products more effectively.

[0016] The fire-resistant frame is further configured such that: the fire-resistant frame includes several connecting legs, and several placement frames are provided between adjacent connecting legs, with a mesh plate fitted onto the surface of each placement frame.

[0017] By adopting the above technical solutions, the connecting legs of the fire-resistant frame can provide stable support for the entire fire-resistant frame, ensuring structural stability after products are placed. The placement frame can divide the products into sections for easy and orderly arrangement and retrieval, avoiding product stacking from affecting heating. The mesh plate has good air permeability, allowing heat and smoke to pass through the mesh plate more fully and contact the products, preventing uneven heating of the bottom of the products due to obstruction.

[0018] To achieve the goal of separating the furnace wall into a steel plate outer shell, an insulation layer, and a refractory layer from the outside in, providing solid structural support for the furnace wall, effectively preventing heat loss from the furnace, directly withstanding the high temperatures inside the furnace, and avoiding damage to the furnace wall due to high temperatures:

[0019] The furnace wall is further configured such that, from the outside to the inside, it consists of a steel plate outer shell, an insulation layer, and a refractory layer.

[0020] By adopting the above technical solution, the furnace wall is divided into a steel plate shell, an insulation layer and a refractory layer from the outside to the inside. The steel plate shell can provide solid structural support for the furnace wall, ensuring the overall stability and deformation resistance of the furnace body. The insulation layer can effectively block the heat inside the furnace from dissipating outward and reduce heat loss. The refractory layer can directly withstand the high temperature inside the furnace and prevent the furnace wall from being damaged by high temperature.

[0021] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0028] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0029] Please see Figures 1 to 5 A burner for uniformly heating products includes a furnace bottom 1, a furnace wall 2 at the top of the furnace bottom 1, and a burner body 3 extending transversely through the bottom of the four outer walls of the furnace wall 2.

[0030] A refractory frame 4 is provided in the middle of the top of the furnace bottom 1, and a fire baffle 5 is provided on the outside of the refractory frame 4.

[0031] A furnace door 6 is hinged to the front outer wall of furnace wall 2.

[0032] In this embodiment, as Figure 1 and Figure 2 and Figure 5As shown, the four burner bodies 3 are symmetrically arranged at the bottom of the outer wall of the furnace wall 2 at the front, back, left and right, with the flame nozzles facing inwards and directly opposite the four sides of the fire baffle wall 5.

[0033] In this embodiment, as Figure 1 and Figure 2 As shown, the fire barrier 5 is rectangular and its height is lower than that of the fire-resistant frame 4.

[0034] In this embodiment, as Figure 1 and Figure 3 As shown, the fire-resistant frame 4 includes several connecting legs 401, and several placement frames 402 are provided between adjacent connecting legs 401. The surface of the placement frames 402 is fitted with a mesh plate 403.

[0035] In this embodiment, as Figure 1 and Figure 4 As shown, the furnace wall 2 is divided into a steel plate outer shell 201, an insulation layer 202, and a refractory layer 203 from the outside to the inside.

[0036] The computer software involved in the hardware carriers such as the burner body in the technical solution is software technology known to those skilled in the art. It is merely applied to the aforementioned hardware carriers. In other words, the computer software portion of the technical solution is an essential technical feature for solving the aforementioned technical problem, constituting a necessary technical feature for the technical problem solved by this application, but it is not a differentiating technical feature or a point of technical improvement. The applicant has not made any technical improvements to the computer software portion involved in the aforementioned related hardware carriers, nor is it a key technical point of the invention.

[0037] Therefore, the "burner body" and other components involved in this application are physical functional modules that combine existing computer software programs or protocols with the hardware carrier of this application. The computer software programs involved in these physical functional modules are technologies known to those skilled in the art and are not improvements of this application. The improvement of this application should be the interaction between the various physical functional modules, that is, the improvement of the overall structure of the burner of this application, in order to solve the corresponding technical problems to be solved by this application.

[0038] The burner that uniformly heats the product operates as follows:

[0039] First, the operator can pull the furnace door 6 outward to rotate and open it around the hinge of the front outer wall of the furnace wall 2. Then, the product to be heated is placed steadily on the mesh plate 403 in the placement frame 402 of the refractory frame 4, and the refractory frame 4 supported by the connecting legs 401 under the product is evenly stressed. Then, the furnace door 6 is pushed to close it against the front outer wall of the furnace wall 2, so as to form a relatively closed space inside the furnace.

[0040] Next, the operator can start the four burner bodies 3 (model: Riello 40GS) through the external controller (model: LMV5). Because they are symmetrically located at the bottom of the front, back, left and right outer walls of the furnace wall 2, they will simultaneously spray flames inward from their respective positions after they are started. The flame nozzles are precisely aligned with the four sides of the fire baffle 5, so that the flames can directly act on the fire baffle 5.

[0041] During this period, the flue gas generated by combustion will be blocked and guided by the fire wall 5, and will begin to circulate counterclockwise or clockwise along the path of the fire wall 5, the furnace wall 2, and the fire wall 5. During the circulation process, the flue gas will fully fill the furnace space, thereby uniformly heating the product.

[0042] During this process, the steel plate shell 201 of the furnace wall 2 provides a stable structural support for the entire device, while its insulation layer 202 can effectively reduce the loss of heat from the furnace to the outside, and the refractory layer 203 can withstand high temperatures to prevent the furnace wall 2 from being burned. At the same time, the furnace bottom 1 always stably supports all components such as the furnace wall 2 and the refractory frame 4, ensuring the stable operation of the entire device.

[0043] Once the product is heated evenly and reaches the desired state, the operator can turn off the four burner bodies 3. After the flame is extinguished, wait for the furnace temperature to drop naturally to a suitable operating level. The operator can then reopen the furnace door 6 and smoothly remove the heated product from the mesh plate 403 of the placement frame 402 of the refractory rack 4.
