Abstract
The invention discloses a kind of corrugated flue for gas-steam boiler, the equally spaced interval of outer wall of described flue be provided with multiple arc groove, the spacing between two adjacent described arc groovesBetween 1st to two/15th 1/10th of described flue length L, distance H of flue mouth inner wall described in the distance from bottom of described arc groove is not less than 16cm.This corrugated flue can either strengthen the disturbance of the flue gas in flue, increases again radiant heat transfer area；Meanwhile, add the rigidity of flue, effectively reduce the swelling stress of flue, be greatly enhanced heat-transfer effect, promote fuel and burn in flue.
Description
Technical field
The present invention relates to boiler technology field, especially, relate to a kind of corrugated flue for gas-steam boiler.
Background technology
Flue is the vitals of gas fired-boiler, plays main impact for fuel combustion and radiant heat transfer efficiency.Pass
The inwall of the flue of system is for facing directly, and this structure cannot carry out disturbance to the flue gas in flue, and radiant heat transfer area is little, unfavorable
Raising in fuel combustion Yu radiant heat transfer efficiency.
Summary of the invention
Present invention aim at providing a kind of corrugated flue for gas-steam boiler, to solve in prior art,
The inwall of traditional flue is for facing directly, and this structure cannot carry out disturbance to the flue gas in flue, and radiant heat transfer area is little, no
It is beneficial to the problem that fuel combustion improves with radiant heat transfer efficiency.
For achieving the above object, the present invention provides a kind of corrugated flue for gas-steam boiler, described flue
The equally spaced interval of outer wall be provided with multiple arc groove, the spacing between two adjacent described arc groovesFor described stove
Between 1st to two/15th 1/10th of gallbladder length L, flue mouth inner wall described in the distance from bottom of described arc groove
Distance H is not less than 16cm.
Further, the width W of described arc groove opening is the spacing between the described arc groove that said two is adjacent1/2nd.
The method have the advantages that
This corrugated flue can either strengthen the disturbance of the flue gas in flue, increases again radiant heat transfer area；Meanwhile, add
The rigidity of flue, effectively reduces the swelling stress of flue, is greatly enhanced heat-transfer effect, promotes fuel at flue internal combustion
Burn.
Accompanying drawing explanation
Below with reference to figure, the present invention is further detailed explanation.The accompanying drawing of the part constituting the application is used for
Thering is provided a further understanding of the present invention, the schematic description and description of the present invention is used for explaining the present invention, is not intended that
Inappropriate limitation of the present invention.In the accompanying drawings:
Fig. 1 is the present invention structural representation for the corrugated flue preferred embodiment of gas-steam boiler.
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiments of the invention are described in detail.
Referring to Fig. 1, the preferred embodiments of the present invention provide a kind of corrugated flue for gas-steam boiler, institute
State flue 1 the equally spaced interval of outer wall be provided with multiple arc groove 2.It is right that the density of setting of arc groove 2 directly affects
The intensity of flue gas disturbance, the quantitative design of arc groove 2 is very little, bad to the effect of flue gas disturbance, but the number of arc groove 2
It is too many that amount designs, and can hinder flue gas flowing in flue 1.Spacing between two adjacent described arc grooves 2Design
Between 1st to two/15th 1/10th of described flue length L, such as, flue length L is 3 meters, two adjacent institutes
State the spacing between arc groove 2 to be between 15cm-20cm, so can be only achieved preferably flue gas disturbance effect；Meanwhile, described
Distance H of flue 1 mouth inner wall described in the distance from bottom of arc groove 2 is not less than 16cm.If the distance from bottom institute of arc groove 2
The distance stating flue 1 mouth inner wall is the least, and flue gas, when flue 1 oral area enters, can be produced back by the obstruction of arc groove 2
Stream, affects fuel combustion.In actual use, the corrugated flue of this structure can either strengthen the flue gas in flue
Disturbance, increases again radiant heat transfer area；Meanwhile, add the rigidity of flue, effectively reduce the swelling stress of flue, greatly
Strengthen greatly heat-transfer effect, promote fuel and burn in flue.This corrugated flue can either strengthen disturbing of the flue gas in flue
Dynamic, increase again radiant heat transfer area；Meanwhile, add the rigidity of flue, effectively reduce the swelling stress of flue, significantly
Strengthen heat-transfer effect, promote fuel and burn in flue.
Preferably, improving the disturbance effect to flue gas further, the width W of described arc groove 2 opening is said two
The adjacent spacing between described arc groove 21/2nd.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention；Skill for this area
For art personnel, the present invention can have various modifications and variations.All within the spirit and principles in the present invention, that is made any repaiies
Change, equivalent, improvement etc., should be included within the scope of the present invention.
Claims (2)
1. the corrugated flue for gas-steam boiler, it is characterised in that:
