Oil burners can be divided into light oil burners and heavy oil burners. Light oil mainly refers to diesel, and heavy oil refers to the heavy oil left after gasoline and diesel are extracted from crude oil; gas burners can be divided into natural gas burners, city gas burners, liquefied petroleum gas burners and biogas burners. As a mechatronic device with a high degree of automation, boiler burners can be divided into five major systems based on the functions they realize: air supply system, ignition system, monitoring system, fuel system, and electronic control system.

The sound-isolating material board 1 34, which is a gypsum board, and the sound-isolating material board 2 35, which is a sound-isolating board, are provided to effectively isolate the sound.

Conversely, the metal baffle 64 is pushed and inserted into the inside of the limiting opening 2 63 and the limiting opening 1 53, and then the magnetic block 67 is pushed to move and inserted into the square opening 65. Due to the adsorption effect of the magnetic block 67 on the metal, it is convenient to install the replaced box body 31.

[0034] The working principle of the device for reducing boiler burner noise is described in detail below.

[0035] The heat-insulating sleeve 32 is provided to protect the noise reduction structure inside the box body 31. The sound-isolating material board 1 34, the gypsum board, and the sound-isolating material board 2 35 are provided to effectively isolate the sound.
