Abstract

The invention relates to an air curtain ring assembly of a combustor. The air curtain ring assembly comprises an air curtain ring, an air curtain groove suspension groove, an air curtain hole, a secondary premixing groove, an air oxygen supplementing ring cavity, cooling fins, an air curtain ring inner ring, an inner edge step of the air curtain ring inner ring and an air curtain ring outer edge wall which are separated and can be assembled together. An induction needle and an ignition needle are arranged on the air curtain groove, and the air curtain groove is formed in the bottom of the air curtain ring to form a complete air curtain ring assembly. By means of the air curtain ring assembly, the air oxygen supplementation problem of the combustor can be solved. Particularly, air outside the assembly can directly supplement oxygen to the root of a fire hole of a burner furnace end in an airflow mode through an air supplementing hole, and sufficient combustion of flames is accelerated; when the combustor is in a dynamic state, air flowing through the suspension groove of the combustor enables an effect similar to an air cushion to be formed between the fire cover of the combustor and the air curtain ring, namely heat insulation of the suspension air is achieved, and therefore the heat effect of the combustor is improved.

Description

technical field [0001] The invention relates to a burner device for a kitchen stove in the field of IPC classification number F23D, in particular to an air curtain ring assembly of the burner. Background technique [0002] With the strengthening of awareness of safety, energy saving, environmental protection and changes in fuel types, structural innovations of kitchen stoves are also emerging. [0003] For example, Chinese patent document CN114060814A discloses a combustion device and a gas stove. The combustion device includes a panel, a combustion part, a first air supply part and a first ejection part, and the combustion part is arranged on the side facing away from the combustion side of the combustion part. Panel, the first air supply part is provided with a first gas port, the first ejection part is connected with the first air supply part and the combustion part, a first air port is arranged between the first ejection part and the air supply part, the first ejection p...
