Inner ring fire cover of combustor

Abstract

The invention discloses an inner ring fire cover of a combustor. The inner ring fire cover of the combustor comprises a cylindrical fire cover body; a through hole is formed in the middle part of the fire cover body to form an air mixing chamber; the lower end surface of the air mixing chamber communicates with an air supply slot in a furnace head seat; a plurality of main fire channels are circumferentially formed at intervals in the fire cover body; one end of each main fire channel communicates with the air mixing chamber, and while the other end of each main fire channel is opened in the vertical surface of the outer side of the fire cover body to form at least one circle of main flame holes which are axially formed at intervals in the fire cover body; a circle of annular flame stabilizing channel is circumferentially formed in the fire cover body; one side of each flame stabilizing channel is opened in the vertical surface of the outer side of the fire cover body to form a circle of flame stabilizing rings, and while the other side of each flame stabilizing channel communicates with the air mixing chamber. The inner ring fire cover of the combustor has the advantages that the main flame of the inner ring fire cover is controlled by the flame stabilizing flame in the flame stabilizing rings to achieve the optimal state, so that the continuous and stable combustion can be achieved, the heat efficiency and the ignition success rate can be increased, and the effect of soft fire without extinguishing can be achieved.

Description

technical field [0001] The invention relates to the technical field of burners, in particular to an inner ring fire cover of a burner. Background technique [0002] At present, the inner ring fire cover of the cooker burner on the market usually uses one or two rings of main flame holes to achieve stable and complete combustion, and then it is equipped with a thermocouple and an ignition needle set in the inner ring fire cover to Play the purpose of high ignition success rate and small fire not to extinguish. However, due to the different types of burners produced by various manufacturers, the complexity of gas costs, and the large difference in gas pressure, if only relying on the main flame hole, the inner ring fire cover will cause flying fire, and the main flame cannot be stably and fully burned. There may even be a flameout phenomenon, affecting the normal use of the user. Contents of the invention [0003] In order to overcome the above-mentioned defects, the prese...
