Anti-weather stable burning apparatus and method for gas flame

Abstract

The invention relates to a gas flame wind-rain proof stably burning device and relative method. It comprises a gas fuel nozzle (1), an outer bottle (2), a inner bottle (3), and porous plate (4). Wherein, the chamber of outer bottle (2) is higher than the inner bottler (3); the inner bottle (3) is inside the chamber; two axes of inner and outer bottles (2, 3) are the same; the mouths of inner and outer bottles (2, 3) are upward; the bottom of outer bottle (2) has a outer air inlet (B); the bottom of inner bottle (3) has a inner air inlet (C); the gas fuel nozzle (1) through the bottom of outer bottle (2) connects the bottom of inner bottle (3); the porous plate (4) is above the inner bottle (3) and fixed at the upper part of outer bottle (2); the porous plate (4) has a mixed airflow outlet (D); and the bottom of gas fuel nozzle (1) has a gas fuel inlet (A). The invention can avoid the gas flame from blown out and keep stable burning in variable conditions.

Description

technical field [0001] The invention relates to a gas combustion method and a combustion device, in particular to a gas flame-resistant and stable combustion device and method capable of burning stably in any stormy atmospheric environment. Background technique [0002] In many practical work and life, people need an ideal gas stable burner to ensure that the gas flame will not be blown out under various external wind directions and even stormy conditions, and maintain a stable gas flame to burn stably. The general understanding of the stable combustion of gas flames has always been on the heating effect of the high-temperature flue gas backflow on the initial fuel flow, which is mainly achieved by the high-temperature flue gas backflow structure produced by a blunt body or a swirler. Due to its inherent high temperature, low speed, and reverse flow properties, the recirculation zone is the most favorable ignition source area in the combustion process, and it can stabilize t...

Problems solved by technology

[0003] Although these methods have achieved great success in the application of industrial combustion systems, the structure of the swirler is relatively complicated, and it is difficult to apply it to ordinary daily life, and whether the simple blunt body can produce backflow and its shape and size after backflow are different. These methods have significant limitations depending on the direction and velocity of the external airflow
