Abstract

The invention discloses an outer fire cover of a burner. The outer fire cover comprises a cylindrical fire cover body. A plurality of main fire holes are formed in the fire cover body at intervals in the circumferential direction. One ends of the multiple main fire holes are communicated with a gas mixing cavity. Two annular flame stabilizing grooves are formed above and below the main fire holes in the outer fire cover body in the circumferential direction of the outer fire cover body. One side of each flame stabilizing groove is formed in the vertical surface of the outer side of the fire cover body so that a circle of stable flames can be formed, and the other side of each flame stabilizing groove is communicated with the gas mixing cavity. A fire transferring groove is formed in the upper surface of the outer fire cover body. One end of the fire transferring groove is divided above the upper flame stabilizing groove and the main fire holes so that the upper flame stabilizing groove and the gas mixing cavity can be communicated. Main flames of the outer fire cover are controlled by flame stabilizing flames in the upper flame stabilizing groove and flame stabilizing flames in the lower flame stabilizing groove at the same time so that the optimal state can be achieved; in addition, the main flames can be pulled by the flame stabilizing flames sufficiently during combustion, continuous and stable combustion of the main flames is achieved, the stability and reliability of fire transferring are improved, and the heat efficiency is improved.

Description

1. Technical field [0001] The invention relates to the technical field of burners, in particular to a burner outer ring fire cover with a flame stabilizing effect. 2. Background technology [0002] At present, the outer ring fire cover of the stove burner on the market is usually below the main fire hole, and the small fire holes arranged alternately with the main fire hole are used to stabilize the flame effect; some of them use a single flame stabilizing groove under the main fire hole to It has the effect of stabilizing the flame. Due to the large differences in gas composition and gas pressure in various regions; the flame stabilization method of relying only on small flame holes and a single flame stabilization groove is not ideal, and the main flame often produces flying flames, which cannot fully and stably burn The phenomenon of flameout occurs, which seriously affects the normal use of users. 3. Contents of the invention [0003] The purpose of the burner outer ...
