Problems solved by technology
The leeward side of the slotted blunt body is easily damaged due to long-term exposure to high-temperature combustion environments, especially for vertical blunt body burners. In the process of the burner, when the properties of the used coal and the designed coal are quite different, it is necessary to move the position of the blunt body or even replace the blunt body to achieve the purpose of efficient pulverized coal combustion. Changing position is more difficult

Embodiment Construction
[0019] The present invention will be described in detail below with reference to the drawings and embodiments. However, it should be understood that the drawings are only provided for a better understanding of the present invention, and they should not be construed as limiting the present invention.
[0020] Such as figure 1 , As described in 2, the slotted bluff body provided by the present invention includes a feed pipe 1, a bluff body body 2, a positioning ring 3 and an anti-dropping device 4. The bluff body 2 is composed of two bluff halves arranged symmetrically. Each half of the bluff body includes an upper bushing 21, a bluff body windward surface 22, a bluff body leeward surface 23, and a lower bushing 24, and the upper bushing 21, the bluff body The body leeward surface 23 and the lower bushing 24 are both semi-annular. The front end of the bluff body windward surface 22 is firmly connected to the outer periphery of the upper bushing 21, and the rear end of the bluff bod...

The invention relates to a slit bluff body. The slit bluff body is characterized by comprising a feeding pipe, a bluff main body composed of two symmetrical half bluff bodies, a locating ring welded to the front portion of the feeding pipe and an anti-disengagement device arranged on the back portion of the feeding pipe, wherein the two half bluff bodies are connected to form the bluff main body through a snap joint type rapid connecting component, so that the rapid mounting and dismounting functions can be achieved; the locating ring is used for accurately locating the bluff main body on the feeding pipe; and the anti-disengagement device is connected between the half bluff bodies and the feeding pipe so as to prevent the half bluff bodies from being disengaged from the feeding pipe. According to the slit bluff body, the position of the bluff main body relative to a nozzle can be changed just by changing the positions of the locating ring and an anti-disengagement ring; and besides, because of the anti-disengagement device, serious accidents such as flameout, detonation and even explosion, caused by falling of the bluff body can be avoided.
Description
Technical field [0001] The invention relates to a core component of a pulverized coal burner, in particular to a slotted bluff body in a slotted bluff body burner. Background technique [0002] Since the slotted bluff body burner has the characteristics of maintaining flame stability, strengthening combustion, saving coal and fuel, it is widely used in the field of pulverized coal combustion. The leeward side of the slotted bluff body is easily damaged due to long-term exposure to high-temperature combustion environments, especially vertical bluff body burners. When the bluff body is damaged, there is also the risk of the bluff body falling off; in the field of industrial boilers, bluff bodies are used In the process of the burner, when the properties of the coal type used and the designed coal type are quite different, the position of the bluff body needs to be moved or even replaced to achieve the purpose of efficient combustion of pulverized coal. However, the existing bluff b...
