[0002] Burner is the common name for the combustion device used in industrial fuel furnaces. It usually refers to the main body of the combustion device, which has a fuel inlet, air inlet and ejection hole. It plays the role of distributing fuel and combustion-supporting air and ejecting them in a certain way for combustion.

[0003] After searching, a Chinese patent with publication number CN208431760U discloses a burner with a protective function, including a body, a mixing chamber is arranged inside the body, one end of the mixing chamber is connected to the air inlet through an air conduit, and a switch valve is installed inside the air conduit.
