Abstract

The utility model provides a combustor provided with a porous high-temperature premixing chamber. The combustor body is formed by an air intake conductor pipe, a high-temperature premixing chamber anda flaming shield, wherein the high-temperature premixing chamber adopts a column structure; a plurality of parallel porous pipe cavities are uniformly distributed in the axial direction of the columnand formed at the upper part of the air intake conductor pipe; a porous crater device is arranged on the surface of the flaming shield and positioned at the upper part of the high-temperature premixing chamber; and a fuel combustion channel is formed by the porous crater device, the high-temperature premixing chamber and the air intake conductor pipe. The utility model has the advantages that thehigh-temperature premixing chamber adopts the structure of the porous pipe cavities, so that when the combustor is used, the fuel and air are fully mixed in all pipe cavities in the high-temperaturepremixing chamber, and the residual heat produced in the combustion process of the stove fully heats mixture gas in the pipe cavities through the high-temperature premixing chamber, thereby realizingfull combustion of the fuel, avoiding backfire in fuel combustion, eliminating combustion explosion, improving the heating efficiency of the stove, saving the fuel, and reducing the environment pollution.

Description

The burner that has porous high temperature premixer

Technical field

The utility model discloses a kind of burner that has porous high temperature premixer, is to the improvement of existing premixer, single chamber burner structure, belongs to gas fuel cooking stove technical field.

Background technology

At present, the mixing chamber of gas fuel cooking stove generally adopts the premixed structure in single chamber, therefore, cooking stove in use, fuel and air are difficult for mixing in the premixer, because the high temperature heating, deflagration phenomenon often appears in the combustion chamber, cause cooking stove tempering or flame-out, bring potential safety hazard to use, influenced the normal use of cooking stove, because premixing effect is poor, cause the cooking stove efficiency of combustion to reduce, also wasted the valuable energy.

Summary of the invention

The utility model provides a kind of burner that has porous high temperature premixer, and the generation of detonation situation appears in cooking stove easily that solved premixer, existing single chamber.

Technical solution of the present utility model is as follows: burner body is made of air intake conduit, high temperature premixer and flame cover, wherein, the high temperature premixer is a column structure, along cylinder axis to being evenly distributed with some parallel porous tube chambers, device is on the top of air intake conduit, the surface of flame cover offers porous bocca device on the top of high temperature premixer, constitutes the fuel combustion passage with high temperature premixer, air intake conduit.

Good effect of the present utility model is: the high temperature premixer adopts the antipriming pipe cavity configuration, fully mixed in fuel and air each tube chamber in the high temperature premixer during use, the waste heat that produces during the cooking stove burning fully heats intraluminal gaseous mixture by the high temperature premixer, thereby realize fuel completing combustion, avoid the fuel combustion tempering, eliminated firing the phenomenon generation, improved the thermal efficiency of cooking stove, save fuel, reduced environmental pollution.
