Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a furnace for the above-mentioned defects of the prior art, which overcomes the low fuel utilization rate of the existing furnace, the ash generated after combustion is more, and part of the heat generated when the fuel is burned is passed through the air. And the loss of the furnace body is difficult to recycle, resulting in a large amount of heat being wasted in vain

Embodiment 1

[0028] Such as Figure 1-3 As shown, the furnace of the present embodiment includes a shell 1 and a furnace liner 2 sealedly connected with the shell 1. The upper and lower ends of the furnace liner 2 are respectively provided with a fuel inlet 21 and an ash outlet 22. The fuel The inlet 21 is used to add fuel into the furnace liner 2, and it also serves as an outlet for flame and flue gas. Both the fuel inlet 21 and the ash outlet 22 are in communication with the outside of the housing 1 to facilitate the addition of fuel and the cleaning of ash. The shell 1 is provided with an air inlet 23, and the side wall of the furnace liner 2 is provided with a multi-stage oxygen supply area from bottom to top, and the multi-stage oxygen supply area is not less than two stages, any of which Oxygen zones are provided with oxygen supply openings that run through the side walls of the furnace liner 2, and the air that enters from the air inlet 23 forms a pressure in the lowermost oxygen s...

Embodiment 2

[0031] Such as Figure 4 , 5 As shown, the overall structure of the furnace of this embodiment is the same as that of Embodiment 1, the difference is that the furnace of this embodiment also includes a windshield 3 arranged on the outside of the furnace liner 2, and the windshield 3 is connected with the inside of the furnace. An air passage 31 is formed between the bladders 2, and the upper end of the windshield 3 is sealed and connected with the furnace inner bladder 2, and the lower end is separated from the furnace inner bladder 2 by an appropriate distance. In addition, a wind guiding interlayer 32 will be formed between the wind deflector 3 and the housing 1 . The setting of the windshield 3 can provide guidance for the air. When the air enters the oxygen supply area covered by the windshield 3, it must first pass through the wind guide interlayer 32 and enter the air passage 31 from the lower end of the windshield 3. , and then pass through the oxygen supply areas at ...

Embodiment 3

[0034] Such as Figure 6 , 7As shown, the overall structure of the furnace of this embodiment is the same as that of Embodiment 2, the difference is that the furnace also includes a blocking plate 4, and the blocking plate 4 is sealingly connected to the housing 1 and the windshield 3, there is an air outlet 41 on it, and the air inlet 23 is located above the blocking plate 4, that is, the air inlet 23 is located on the casing 1 where the sealing position between the blocking plate 4 and the casing 1 is above the sealing position. Location. The blocking plate 4 divides the entire cavity between the shell 1 and the furnace liner 2 into upper and lower cavities, and connects the upper and lower cavities through the air outlet 41 . Further, also because the most serious heat dissipation area of ​​the furnace liner 2 is mainly concentrated in its upper position, the blocking plate 4 is also arranged at the upper middle position of the housing 1, so that the upper cavity forms a ...

Abstract

The invention relates to the field of environment-friendly stoves, in particular to a hearth. The hearth comprises a shell and a hearth liner. The hearth liner is hermetically connected with the shell. A fuel inlet and an ash outlet are arranged at the upper end and the lower end of the hearth liner and are communicated with the outside of the shell. An air inlet is arranged on the shell. Multiple levels of oxygen supply areas are arranged on the side wall of the hearth liner from bottom to top. Any level of oxygen supply area is provided with an oxygen supply opening penetrating the side wall of the hearth liner. The pressure generated by air entering the air inlet at the lowest oxygen supply area is larger than that generated by any above oxygen supply area. After entering the hearth from the air inlet, the air fully absorbs heat diffused by the hearth liner to become high-temperature combustion air and then carries back the heat to the hearth liner through the oxygen supply openings to recycle the heat, so that dissipation of the heat of the hearth is reduced to the greatest extent without use of heat-insulating materials and heat-insulating measures; full combustion of fuel is facilitated, utilization rate of the fuel is increased, and ash is reduced.

Description

technical field [0001] The invention relates to the field of environment-friendly cookers, in particular to a furnace. Background technique [0002] In life, large and small hotels, restaurants, factory canteens, school canteens, families, etc. all need to use stoves, and the hearth is the core component of the stove. With the development of social economy and the gradual consumption of resources, energy conservation and emission reduction have become the only way to achieve sustainable development. Along with the development of society and economy, the environmental protection requirement to stove is also higher and higher. In the traditional furnace, it is difficult for the fuel to be fully burned when the fuel enters the furnace, and more ash is produced after combustion, thereby reducing the utilization rate of the fuel; part of the heat generated during combustion is difficult to dissipate through the air and the furnace body Recycling causes a lot of heat to be waste...
