The invention discloses a burning stabilizing ring structure of a vortex burner. The burning stabilizing ring structure comprises a burning stabilizing ring body and further comprises a plurality of flame stabilizing teeth, a pressing plate and a bolt assembly. The flame stabilizing teeth are pressed to the burning stabilizing ring body through the pressing plate. The pressing plate is arranged on the burning stabilizing ring body. The bolt assembly penetrates through the burning stabilizing ring body, the pressing plate and the flame stabilizing teeth, so that the flame stabilizing teeth are fixed to the burning stabilizing ring body at equal intervals, and the windward faces of the flame stabilizing teeth are made from silicon carbide. The silicon burning stabilizing ring can resist high temperature and abrasion, the burning stabilizing teeth can be effectively prevented from falling off, the service life of the burner is prolonged, and safety and economy of a power plant are improved.
