Description

Technical Field

[0001] This utility model relates to the field of combustion furnace technology, and in particular to a single-layer high-temperature gasification combustion furnace. Background Technology

[0002] Firewood undergoes two stages of combustion: primary combustion and secondary combustion. Primary combustion occurs at lower temperatures (approximately 280°C to 480°C), where moisture in the firewood evaporates and volatile gases (such as methane and carbon monoxide) are released, but most of the combustible gases remain unburned. Secondary combustion occurs when temperatures reach above 600°C, at which point the combustible gases mix thoroughly with oxygen and burn, releasing a large amount of heat. Current gasification combustion furnaces utilize this principle, controlling air inflow to promote the pyrolysis and gasification of the firewood, ensuring that the combustible gases fully contact and burn with the air within the furnace, thereby improving combustion efficiency.

[0003] CN 119755621 A discloses a firewood gasification furnace, including a furnace body, which includes a combustion chamber and a preheating chamber disposed outside the combustion chamber. Several partitions are vertically arranged within the preheating chamber, dividing it into several preheating channels. Air inlets are provided on the outer walls of the preheating channels, and air outlets communicating with the combustion chamber are provided through the inner walls of the preheating channels. The air outlets are vertically higher than the air inlets. Air enters the preheating channels through the air inlets, is preheated within the preheating channels, and then enters the combustion chamber through the air outlets to participate in combustion.

[0004] However, the combustion chamber of the aforementioned wood-fired gasification furnace is surrounded by a preheating chamber, which means that the heat generated by the furnace needs to pass through multiple furnace walls to dissipate, thus affecting the furnace's heat dissipation efficiency. Furthermore, the double-layered furnace walls result in a larger overall furnace volume, occupying more space and making it inconvenient to carry. In addition, when air is in the preheating chamber, it is only heated on one side, resulting in a small heating area. Consequently, the air temperature remains low when it enters the combustion chamber, affecting combustion efficiency. Moreover, the air entering the combustion chamber flows from the outside in, leading to uneven air distribution. During combustion, the combustible gases distributed at the edges of the combustion chamber will come into contact with and burn the air first, consuming most of the air. This means that the air entering the center of the combustion chamber is insufficient for the combustible gases located in the center to burn completely. The unburned combustible gases will form flue gas and be discharged from the furnace opening. The discharged flue gas not only has an odor but also pollutes the environment. Utility Model Content

[0020] To more clearly illustrate the technical solution of this utility model, the following description is made in conjunction with the accompanying drawings. Obviously, the drawings described below are only one embodiment of this utility model. For those skilled in the art, other embodiments can be obtained based on these drawings and embodiments without creative effort, and all of them fall within the protection scope of this utility model.

[0021] according to Figure 1-11 As shown, a single-layer high-temperature gasification combustion furnace includes a furnace body 1. Several sets of induced draft pipes 2 are arranged horizontally inside the furnace body 1. Several sets of first air outlets 22 are opened on the induced draft pipes 2. An air duct 3 is fixedly installed on the inner front wall of the furnace body 1, and the air duct 3 is connected to the induced draft pipes 2. An air inlet 1021 corresponding to the position of the air duct 3 is opened on the side wall of the furnace body 1. A first furnace opening 1031 is opened at the rear top of the furnace body 1, and a first chimney connector pipe 5 is fixedly installed at the first furnace opening 1031. A second furnace opening 1032 is opened at the front top of the furnace body 1, and a pad 1033 is fixedly installed at the bottom end of the second furnace opening 1032. Furnace opening accessories are fitted on the pad 1033. A fuel inlet 1011 is opened on the front side wall of the furnace body 1, and a furnace door 6 is fitted at the fuel inlet 1011.

[0022] In the above specific embodiment, the induced draft pipe 2 is entirely inside the furnace. By heating the air from all sides, the heating area of ​​the air inside the pipe is increased, resulting in a preheating temperature of the air inside the pipe that is much higher than that of the air preheated in the existing outer furnace chamber. This, in turn, increases the secondary intake temperature and improves combustion efficiency. Furthermore, the furnace body 1 adopts a single-furnace design, which reduces the volume of the furnace body 1 while maintaining the same combustion chamber volume, thus reducing space occupancy and making it easier for users to carry. During use, combustibles are placed on the bottom crossbar of the induced draft pipe 2 for primary combustion. The flue gas generated during combustion moves towards the top of the furnace body 1. Air from outside the furnace enters the induced draft pipe 2 through the air duct 3. As the air flows in the induced draft pipe 2, it is preheated by the heat released during the primary combustion of the combustible material. The preheated air is discharged into the furnace body 1 through the first exhaust port 202. Because the induced draft pipes 2 are relatively compact, the flue gas can fully contact the air when passing through the gaps between the induced draft pipes 2, thereby avoiding incomplete combustion of the flue gas and preventing the flue gas generated during combustion from being discharged outside the furnace body 1, thus reducing the pollution to the environment.

[0023] This embodiment provides a single-layer high-temperature gasification combustion furnace. To increase the air coverage area within the furnace body 1, the top crossbar of the induced draft pipe 2 adopts a structure of alternating high and low heights, allowing air to be distributed in multiple layers within the furnace body 1. This ensures sufficient air supply at the top of the furnace body 1 for secondary combustion of the flue gas. The specific technical solution is as follows: according to Figure 7 As shown, the number of exhaust pipes 2 is odd, the exhaust pipes 2 have a C-shaped structure, the bottom horizontal bar of the exhaust pipe 2 is fixedly installed on the air duct 3, the bottom horizontal bar of the exhaust pipe 2 has an air inlet 21, the top horizontal bars of adjacent exhaust pipes 2 are staggered at different heights, the first air outlet 22 is horizontally set on the side wall of the top horizontal bar of the exhaust pipe 2, wherein the first air outlet 22 on the two sets of exhaust pipes 2 near the end of the air duct 3 is inclined towards the inside of the furnace body 1 at an angle of 40-50 degrees, and several sets of second air outlets 23 are opened on the front side of the vertical bar of the exhaust pipe 2, wherein the second air outlets 23 on the two sets of exhaust pipes 2 near the end of the air duct 3 are inclined towards the inside of the furnace body 1 at an angle of 40-50 degrees.

Support legs 105 installed at the bottom of the furnace body 1 can be retracted for easy storage or transport. The specific technical solution is as follows: according to Figure 6As shown, the furnace body 1 includes a first side plate 101 and a second side plate 102. Both the first side plate 101 and the second side plate 102 are L-shaped structures. The first side plate 101 and the second side plate 102 are connected end to end.

A bottom plate 104 is fixedly installed on the bottom of the first side plate 101 and the second side plate 102. Support legs 105 are hinged to the front and rear ends of the bottom of the first side plate 101 and the second side plate 102.

When it is necessary to add combustibles to the furnace body 1, the user holds the switch lever 6022 and moves the door switch 602, causing the hook portion 6021 on the door switch 602 to disengage from the slot 1012, thereby opening the furnace door 6.
