'一种高性能燃烧器'中公开了一种使用生物质燃料的炉具的燃烧器。该燃烧室
包含一个与进料管一端相连通的第一燃烧区,一个紧接第一燃烧区的第二燃烧区,一个紧接第二燃烧区的第三燃烧区。第一燃烧区包括一块基本水平的第一底板、两块斜置的第一侧板、一块从第一底板向上延伸的第一前板、以及与第一底板相对的第一上方开口。出料口穿过第一前板使得进料管与第一燃烧区连通。两块第一侧板之间的距离在出料口处与出料口的宽度基本相同,沿从第一燃烧区向第二燃烧区方向宽度逐渐增加。第二燃烧区包括一块沿第一底板向下倾斜延伸的第二底板以及与第二底板相对的第二上方开口。第二底板相对于第一底板向下倾斜的角度可为
8 ° -30
°。第三燃烧区包括一块第三底板、一块从第三底板向上延伸至第二底板的前竖板、一块从第三底板向下延伸至底面的后竖板、以及一个与第三底板相对的第三上方开口。 The inventor of the invention filed in China 201110257871.8
A burner for a stove using biomass fuel is disclosed in 'A High Performance Burner'. The combustion chamber
A first combustion zone is provided in communication with one end of the feed tube, a second combustion zone immediately adjacent the first combustion zone, and a third combustion zone immediately adjacent the second combustion zone. The first combustion zone includes a substantially horizontal first bottom plate, two inclined first side plates, a first front plate extending upward from the first bottom plate, and a first upper opening opposite the first bottom plate. The discharge port passes through the first front plate such that the feed tube is in communication with the first combustion zone. The distance between the two first side plates is substantially the same as the width of the discharge opening at the discharge opening, and gradually increases in width from the first combustion zone to the second combustion zone. The second combustion zone includes a second bottom plate extending obliquely downward along the first bottom plate and a second upper opening opposite the second bottom plate. The angle at which the second bottom plate is inclined downward relative to the first bottom plate may be
8 ° -30
°. The third combustion zone includes a third bottom plate, a front riser extending upward from the third bottom plate to the second bottom plate, a rear riser extending downward from the third bottom plate to the bottom surface, and a third opposite the third bottom plate Three openings above.
在实际使用过程中发现这种燃烧室的性能还存在有提升的空间。首先,虽然第一底板上方的第一燃烧区是主燃烧区,但燃烧的燃料在被新从进料管进入到第一底板的燃料从第一底板推动而落入第二底板之上的时候尚未燃尽,仍具有很大的能量,即使落入第三燃烧区时也仍然未完全燃尽。而三个燃烧区的能量是分别从三个上方开口处向上进入能量交换区,这样能量交换区的面积过大,不利于能量的集中使用,会造成浪费。第二,主燃烧区的第一底板基本是一个水平的平面,燃烧的燃料呈水平分布,并容易掉落第二燃烧区中,不易累积一定的燃料厚度。而实践证明比较薄的燃料厚度不易形成较高的燃烧温度。第三,由于燃料累计厚度较薄,在进料管与第一燃烧区相连通的地方就不易累积起尚未点燃的燃料。在实际操作中发现燃料基本上会从此处落入至第一底板上然后开始燃烧,这样就会在进料管与第一燃烧区相连通的地方形成很高的燃烧温度,从而非常容易引燃进料管内的燃料,造成回火。
There is still room for improvement in the performance of such a combustion chamber during actual use. First, although the first combustion zone above the first bottom plate is the main combustion zone, the fuel burned when the fuel newly introduced from the feed pipe to the first bottom plate is pushed from the first bottom plate and falls onto the second bottom plate. It has not burned out and still has a lot of energy, even if it falls into the third burning zone, it is still not completely burned out. The energy of the three combustion zones enters the energy exchange zone from the three upper openings respectively, so that the area of the energy exchange zone is too large, which is not conducive to the concentrated use of energy and waste. Second, the first bottom plate of the main combustion zone is basically a horizontal plane, and the fuel burned is horizontally distributed, and is easily dropped into the second combustion zone, and it is difficult to accumulate a certain fuel thickness. Practice has shown that a relatively thin fuel thickness is not easy to form a higher combustion temperature. Third, since the cumulative thickness of the fuel is relatively thin, it is difficult to accumulate unburned fuel where the feed pipe is in communication with the first combustion zone. In actual operation, it is found that the fuel will basically fall from here to the first bottom plate and then start to burn, which will form a high combustion temperature in the place where the feed pipe communicates with the first combustion zone, so that it is very easy to ignite. The fuel in the feed pipe causes tempering.
本发明所要解决的一个技术问题是提供一种新型燃烧器,其具有集中的热交换区,能量集中使用,热量的利用率较高。
One technical problem to be solved by the present invention is to provide a novel burner having a concentrated heat exchange zone, concentrated use of energy, and high heat utilization.
本发明所要解决的另一个技术问题是提供一种新型燃烧器,该燃烧器可以累计较厚的燃料厚度,从而具有较高的燃烧温度。
Another technical problem to be solved by the present invention is to provide a novel burner that can accumulate thicker fuel thicknesses and thus have a higher combustion temperature.
本发明所要解决的另一个技术问题是提供一种新型燃烧器,该燃烧器在送料筒与燃烧器相连通的地方可以累积尚未点燃的燃料,从而降低此处的温度,减少回火的可能性。
Another technical problem to be solved by the present invention is to provide a novel burner which can accumulate unburned fuel where the feed cylinder communicates with the burner, thereby reducing the temperature here and reducing the possibility of tempering. .
