Description

Technical Field

[0001] This utility model specifically relates to a combustion furnace structure based on refractory materials. Background Technology

[0002] A combustion furnace is a device used to heat or burn materials. Its basic principle is to generate heat energy through the combustion of fuel, which is then used to heat the materials inside the furnace or for other processes. The fuels for solid combustion furnaces typically include coal, wood, biomass, solid waste, etc.

[0003] In existing solid fuel combustion furnaces, solid fuel is usually burned directly on the grate inside the furnace body. During the combustion process, the flue gas is directly discharged through the flue gas outlet on one side of the furnace body. The flue gas has a short residence time in the furnace body, resulting in poor combustion efficiency. In addition, the furnace body only has a single ventilation opening, which leads to uneven air distribution inside the furnace body and poor contact with the fuel. To address this, we propose a combustion furnace structure based on refractory materials. Utility Model Content

[0004] The purpose of this invention is to provide a combustion furnace structure based on refractory materials to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a combustion furnace structure based on refractory materials, comprising:

[0006] The furnace body has a feed inlet on one side and a combustion port on the furnace body.

[0007] A grate is located in the middle of the inner side of the furnace body, and a ventilation module is provided on the inner side of the furnace body corresponding to the area below the grate;

[0008] The first smoke guide block is fixed on the grate;

[0009] The second smoke guide block is disposed inside the first smoke guide block, and a first flue is formed between the second smoke guide block and the first smoke guide block to retain the flue gas. The first smoke guide block and the inner wall of the furnace body form a second flue.

[0010] Preferably, a smoke exhaust port is provided on the other side of the furnace body, corresponding to the middle of the first smoke guide block.

[0011] Preferably, the second smoke guide block is arc-shaped, and the second smoke guide block is symmetrically arranged in two places along the midpoint of the first smoke guide block.

[0012] Preferably, the ventilation module includes a ventilation pipe, an air outlet, and an air inlet. The ventilation pipe is fixed to the inner wall of the furnace body, and multiple air outlets are evenly distributed along its circumference. One end of the ventilation pipe penetrates the outer wall of the furnace body to form an air inlet.

[0013] Preferably, the air inlet is trumpet-shaped.

[0014] Preferably, the furnace body includes an outer shell, refractory bricks, and a corundum refractory layer. Refractory bricks are fixed inside the outer shell, and the inner side of the refractory bricks has a corundum refractory layer.

[0015] Preferably, the first smoke guide block is C-shaped.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This invention, by incorporating a first smoke guide block, a second smoke guide block, and a first flue, avoids the direct discharge of flue gas from the exhaust port after combustion, as is common in traditional fuel combustion. This device effectively extends the residence time of flue gas inside the furnace, thereby improving the combustion efficiency of the flame and reducing fuel waste. It also effectively purifies the flue gas, enhancing its practicality. Furthermore, the inclusion of a ventilation pipe, air outlet, and air inlet avoids uneven air distribution within the furnace, which can lead to incomplete combustion. This device ensures even air distribution throughout the furnace, improving combustion efficiency. Additionally, the use of composite refractory materials enhances the furnace's insulation and fire resistance. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-4 This utility model provides a technical solution: a combustion furnace structure based on refractory materials, comprising:

[0025] Furnace body 1, with a feed inlet 2 on one side and a combustion port 3 on the furnace body 1;

[0026] A grate 5 is located in the middle of the inner side of the furnace body 1, and a ventilation module 4 is provided on the inner side of the furnace body 1 corresponding to the area below the grate 5.

[0027] This allows air to blow upwards from below the grate 5, enabling better contact between natural wind and the fuel on the grate 5, thus improving oxygen supply.

[0028] The first smoke guide block 7 is fixed on the grate 5;

[0029] The second smoke guide block 8 is disposed inside the first smoke guide block 7, and a first flue 9 for retaining flue gas is formed between the first smoke guide block 7 and the first smoke guide block 7. The first smoke guide block 7 and the inner wall of the furnace body 1 form a second flue.

[0030] This allows for a longer period of time after combustion, during which the flue gas lingers inside the furnace body 1, thereby improving the flame's ability to fully combust the flue gas, increasing energy efficiency, and reducing the pollution caused by organic matter in the flue gas to the outside.

[0031] In this embodiment, preferably, a smoke exhaust port 6 is provided on the other side of the furnace body 1, corresponding to the middle of the first smoke guide block 7.

[0032] In this embodiment, preferably, the second smoke guide block 8 is arc-shaped, and the second smoke guide block 8 is symmetrically arranged in two places along the midpoint of the first smoke guide block 7.

[0033] This facilitates better improvement of the movement trajectory of flue gas inside the furnace body 1.

[0034] In this embodiment, preferably, the ventilation module 4 includes a ventilation pipe 401, an air outlet 402 and an air inlet 403. The ventilation pipe 401 is fixed to the inner wall of the furnace body 1. Multiple air outlets 402 are evenly distributed along the circumference of the ventilation pipe 401. One end of the ventilation pipe 401 penetrates the outer wall of the furnace body 1 to form an air inlet 403.

[0035] This facilitates air distribution and more evenly fills the inner side of the furnace body 1, thereby improving the contact and combustion effect between air and fuel.

[0036] In this embodiment, preferably, the air inlet 403 is trumpet-shaped.

[0037] This facilitates better airflow into the inside of the ventilation duct 401.

[0038] In this embodiment, preferably, the furnace body 1 includes an outer shell 101, refractory bricks 102 and a corundum refractory layer 103. Refractory bricks 102 are fixed inside the outer shell 101, and the corundum refractory layer 103 is provided inside the refractory bricks 102.

[0039] This facilitates better fire resistance and heat preservation, and improves the fire resistance strength of furnace body 1.

[0040] In this embodiment, preferably, the first smoke guide block 7 is "C" shaped.

[0041] This allows the flue gas to be moved further away from the exhaust port 6 during combustion, thereby extending the residence time of the flue gas inside the furnace body 1 and improving the combustion efficiency.

[0042] The working principle and usage process of this utility model are as follows: During use, fuel is fed into the inside of the furnace body 1 through the feed inlet 2, and the fuel is burned on the grate 5. The flue gas from the combustion flows into the second flue through the first flue 9, and is finally discharged to the outside through the exhaust port 6. The first flue 9 and the second flue facilitate the increase of the residence time of the flue gas inside the furnace body 1. The flame inside the furnace body 1 burns the flue gas again, improving fuel utilization efficiency and the purification effect of the flue gas. External air flows into the inside of the ventilation pipe 401 through the air inlet 403 and is blown out from multiple air outlets 402, improving the uniformity of air distribution and ensuring that the fuel is fully and evenly burned in multiple places inside the furnace body 1.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
