Description

Technical Field

[0001] The invention belongs to the field of boiler burner devices, and in particular relates to a wall-type tangential-circle burner and a working method thereof. Background Art

[0002] The boiler is an important energy conversion equipment, which is widely used in industrial production and daily life. The boiler consists of two major parts: the pot and the furnace. The heat energy released by the combustion of fuel or other heat energy is used to heat the working medium water or other fluids to certain parameters. At this time, a wall-type tangential burner will be needed to heat the boiler.

[0003] The wall-type circular burners and working methods currently on the market have the following problems when used: 1. When the traditional wall-type tangential circular burner and its working method are actually used, since the burner needs to be installed on the boiler when using the burner, the traditional wall-type tangential circular burner is only installed and fixed by a flange, and has no other fixing method. The burner body is large in size and heavy in weight. At this time, after the burner is installed, its stability is poor; 2. Most wall-mounted circular burners and working methods are exposed to the outside after installation and are not equipped with protective devices. When the wall-mounted circular burner is hit during use, it may cause the burner to shake or tilt, or even directly cause damage to the burner itself, and the protection is poor during use; 3. During the use of most wall-mounted circular burners and working methods, since the burner is installed by directly penetrating the burner flange with bolts, the burner is installed and fixed on the boiler. At this time, there is no other connection method. When the burner is hit during use, it may cause the burner to fall, and the connection strength is low during use. Summary of the invention
