The burner cover is a key device fixed around the burner head, mainly used to protect the burner and surrounding equipment from high temperature damage. The burner cover reduces the damage to the equipment by high temperature through the cooling system, thereby extending the service life of the equipment. This design not only improves production efficiency, but also reduces maintenance costs, bringing significant economic and safety benefits to the enterprise.

[0003] The burner hood of the pulverized coal burner in the gasifier disclosed in the Chinese patent application publication specification CN212565752U, the hood body formed by the pipe ring of the device can effectively isolate the heat radiation of the flame in the furnace to the pulverized coal burner, thereby well protecting the pulverized coal burner, greatly extending the service life of the pulverized coal burner, effectively saving the maintenance cost of the equipment, and also ensuring the smooth operation of the entire gasifier.

[0004] However, during the implementation of the technical solution of the above patent, the installation and disassembly of the burner hood is rather cumbersome. Most of the existing burner hoods are installed on the burner by a flange through multiple bolts. When fixing with this multiple bolt installation method, in order to avoid gaps in the installation position caused by the flange tilting and ensure uniform force, the multiple bolts need to be symmetrically cross-tightened and tightened in stages, so that the multiple bolts need to be twisted slowly and multiple times, and the process is rather cumbersome. The burner hood is used in a high temperature environment and is easily damaged. It needs to be frequently removed for maintenance or replacement. This bolt fixing method is inconvenient during disassembly. Utility Model Content
