Stove combustor and process for manufacturing combustion disk in combustor

Abstract

The invention relates to a burner of cooking utensils and a preparation technology of a tray for combustion in the burner. The burner comprises a distributor, a tray for combustion, a base seat and an ignition device, wherein, the distributor consists of an external distributor and an internal distributor; the tray for combustion is provided with three rings of fire, three grooves for flame stabilization and four overall channels, has a maximum sectional drift diameter necessary for gas to enter into the tray for combustion and leaves four fan-shaped secondary air inlets at the bottom of the tray so as to ensure the secondary air supply to inner ring fire and central fire. Induction tunnels communicated with a gas pipe for main fire and a gas pipe for central fire are arranged on two staggered horizontal planes with independent gas intake, which greatly saves gas kinetic energy and reduces resistance in air intake by the induction tunnels. The burner can ensure enough primary air intake without yellow flame, flashback and blow-off for more full burning. The preparation technology provided by the invention can ensure high surface smoothness of the tray for combustion and high precision in dimension of an inner cavity, smooth flow of gas and reduction in loss of gas kinetic energy so as to improve the efficiency of gas combustion.

Description

technical field [0001] The invention relates to a device used on a gas stove, in particular to a stove burner. The invention also relates to the preparation process of the combustion disk in the burner. Background technique [0002] At present, most of the burners in the gas stoves sold on the market and used at home have adopted three-ring fire and double-jet gas technology. The gas is ejected by two gas ejectors respectively, and the gas ejected by the two gas ejectors is divided into a central fire, an inner ring fire and an outer ring fire by a combustion disc and a flame distributor, forming a three-ring flame. Although the flame distribution of this type of burner is uniform, the area acting on the bottom of the pot is enlarged, and the combustion efficiency is improved. But there are also the following disadvantages: [0003] 1. If figure 1 , figure 2 As shown in FIG. 2 , there are two structural schematic diagrams of the connection between the existing double e...

AI Technical Summary

Problems solved by technology

The walls of the air cavity of the combustion disc 2 and the fire cover 3 of the traditional technology are relatively thick, and the space in the air cavity is occupied when the screw is fastened, and the inner diameter cross-sectional area of ​​the air cavity is reduced, causing the gas to go through multiple turns, and the gas pressure is damaged again , especially artificial gas with a fast burning speed is easy to temper, (tempering is a major defect of the burner)

In order to ensure a sufficient diameter of the air cavity, if the size is increased outward, the secondary air passage at the bottom of the combustion pan will inevitably be reduced. Insufficient supplementary secondary air will also cause excessive carbon monoxide in the flue gas

At the same time, it is not conducive to the heat balance of the burner, and will reduce the effective service life of thermocouples, ignition needles and other devices installed between the central fire and the inner ring fire.

Therefore, the cross-sectional diameter of the gas inlet and outlet of the base and the combustion disc in the prior art is small, the resistance is large, the gas is not smooth, and the power is difficult to increase

[0005] 3. There is no flame stabilizing groove in the existing burner, which cannot fully adapt to the combustion speed of various gas sources in my country

Therefore, a flange is added to the lower part of the fire groove of the external firearm, and some fire transmission is slow, and severe deflagration will be caused.

For thinner external firearms, the ignition groove is deeper, and the strength decreases, causing deformation and affecting its free disassembly
