Embodiment

[0027] Such as figure 1 As shown, the high-power heat exchange burner described in this embodiment mainly includes a heat exchanger 1, an air inlet pipe 4 arranged on the heat exchanger 1, and a combustion chamber connected to the heat exchanger 1 and the air inlet pipe 4 3. The mixer 2 arranged inside the combustion chamber 3, the ejector 5 communicated with the air inlet pipe 4, and the main gun 6 and the ignition gun 7 communicated with the mixer 2.

[0028] Wherein, the heat exchanger 1 is the core heat exchange component of this embodiment, and its specific structure is as follows: figure 2 shown. That is to say, the heat exchanger 1 as a whole is a coaxial circular seam structure with more than 3 layers, which is mainly composed of an exchange cylinder 11, an inner finned tube 12 set on the outer side of the exchanged tube 11, and an outer finned tube 12 placed on the outer side of the inner finned tube 12. The fin tube 13 is composed of a shell 14 sleeved on the outs...

Abstract

The invention discloses a high-power heat exchange burner for an industry kiln stove. The high-power heat exchange burner for the industry kiln stove is characterized by being mainly composed of a heat exchanger (1), an air inlet pipe (4), a combustor (3), a mixer (2) and a main gun (6), the heat exchanger (1) is provided with an air channel and an exhaust gas channel, the air inlet pipe (4) is arranged on the heat exchanger (1) and communicated with the air channel of the heat exchanger (1), the combustor (3) is communicated with the air channel of the heat exchanger (1) and the air inlet pipe (4), the mixer (2) is arranged in the combustor (3), and the main gun (6) is communicated with the mixer (2) and used for conveying fuel gas. The heat exchanger and the burner are integrated, the high-power heat exchange burner is suitable for fuel media such as natural gas, coke oven gas and producer gas, preheated combustion air and fuel gas can be fully mixed and burnt in the combustor after being mixed, and the maximum burning power reaches 4000 KW and is more than twice that of a traditional burner.

Description

technical field [0001] The invention relates to a burner, in particular to a high-power heat-exchanging burner for industrial kilns that can use natural gas, coke oven gas, and producer gas as fuel media. Background technique [0002] At present, burners with self-preheating structure have been widely used in industrial kiln burner technology, and the preheating of combustion air is generally realized by adding independent heat exchangers. Although the burner of the self-preheating structure has a better use effect, it still has the following defects: [0003] First, due to the addition of an independent heat exchanger on the burner with its own preheating structure, the volume of the entire device is relatively large, and its installation is extremely inconvenient. [0004] Second, since the burners with self-preheating structure are realized by one-time heat exchange, the heat exchange power is generally less than 1500KW. In some large-load industrial furnaces, the only w...
