Three-ring fire combustor

Abstract

The invention discloses a three-ring fire combustor and relates to the technology of household gas stove combustion. In order to solve the problem that an existing household gas stove combustor is low in heat efficiency, the technical scheme is provided. The three-ring fire combustor is characterized by being composed of a main fire combustor body, an auxiliary fire combustor body and a small fire combustor body. The main fire combustor body and the auxiliary fire combustor body are closely next to each other. The number of fire stabilizing holes is half of the number of main fire holes. Or a fire cover is provided with a torch, and the torch is provided with fire holes; fuel gas is sprayed out in the clockwise direction of the fire cover from the fire holes in the torch, and rotary fire is formed. During ignition, the small fire combustor body is firstly ignited, the main fire combustor body is ignited by the small fire combustor body, and the auxiliary fire combustor body is ignited by the main fire combustor body. When it is needed to turn down a fire behavior, the auxiliary fire combustor body and the main fire combustor body are turned off in sequence.

Description

technical field

[0001] The technical proposal relates to the combustion technology of household gas stoves. Background technique

[0002] At present, most household burners are composed of a main burner and a small fire burner. Its disadvantage is that it is necessary to adjust the fire of the main burner to a small value, which can only reduce the air pressure of the main burner to make the flame smaller; because the flame becomes smaller, the distance between the flame and the bottom of the pot is large, and the thermal efficiency is low. Individual household burners have a three-ring fire, but the outer ring fire is too far away from the center of the burner. For a pointed bottom pot, the firepower of the outer ring flame has been reduced when it reaches the bottom of the pot. Also have the steady fire fire hole on the fire cover equal to the main fire fire hole quantity, block the oxygen supply of part main fire and let the waste gas. Contents of the invention [000...
