Two-way isobaric and porous equalized air supply and double-layer mixed air adjustment device for burners

Abstract

The invention discloses a bidirectional isobaric porous equal air supply and double-layer wind mixing regulating device used for a combustor. The device comprises a base, an air supply wind mixing regulating unit and a supply distributor. The base comprises an upper base body and a lower base body. The air supply wind mixing regulating unit is arranged in a cavity and comprises an upper air valve, an injection intensifier and a lower air valve. The injection intensifier is fixedly arranged between the upper air valve and the lower air valve. A cavity defined between the lower air valve and the injection intensifier is a first air supply wind mixing chamber. A cavity defined between the upper air valve and the injection intensifier is a second air supply wind mixing chamber. The supply distributor is fixed to the bottom of the lower base body and comprises a middle air supply tube, an annular air supply tube and an air supply tube fixing piece. The air supply tube fixing piece is used for fixing the middle air supply tube and the annular air supply tube to the bottom of the lower base body.

Description

technical field [0001] The invention relates to the technical field of burners, in particular to a two-way isobaric multi-hole equalized air supply and double-layer mixed air regulating device for a burner. Background technique [0002] There have been a number of gas stoves with combined burners on the side of the column cavity and firearms on the market. Although the burners of this gas stove have a good energy-saving effect, it has been found through its use and in-depth experimental research that due to the need for multiple The multiple air supply holes of the side port type fire distributor of the column chamber cannot supply the gas at equal pressure, which leads to the inconsistency between the air output volume of each hole and the injection mixed air volume, and then the flames ignited by the multiple column chamber fire distributors are of different sizes. etc., some deflagrate and leave the flame, some have yellow flame and red fire; at the same time, there is al...

Problems solved by technology

[0003] The purpose of the present invention is to overcome the problem of unequal air supply from one-way air source to the multi-holes and the problem that the rated power and mixed air volume will gradually decrease with the increase of temperature in the fire distributor cavity due to the influence of "thermal resistance" in the fire distributor cavity. Provide a simple structure, can form an isobaric loop for air supply, and can form a kind of bidirectional isobaric multi-hole equal quantitative air supply and double-layer air mixing adjustment device for a burner that can counteract the "thermal resistance" function, so as to fundamentally Realize the equalization of multi-hole air supply and the balance and stability of rated power and mixed air volume
