One end be in low level.After forming condensed water in internal layer condensing heat-exchanging pipe, outer layer condensing heat-exchanging pipe, if not
Discharge in time, heat transfer effect can be affected, therefore it is obliquely installed and condensed water can be made to discharge rapidly.
As preferably, described internal layer condensing heat-exchanging pipe, outer layer condensing heat-exchanging pipe with the angle of inclination of horizontal plane are
3-7 degree.Because high-temperature flue gas moves upward, if angle of inclination is excessive, fume emission can be affected even
Backflow.Angle in this range tilts to ensure that condensed water is discharged rapidly, does not interferes with again flue gas
Discharge.
As preferably, the inwall of described flue is provided with ripple.The setting of ripple can not only increase in flue
The surface area of wall, and it is prone to radiant heat transfer after forming curved surface.
Being compared with the prior art, the beneficial effects of the utility model are: efficient water-heating combustion gas of the present utility model
Boiler heat exchange efficiency is high, and can be discharged by condensed water in time, improves heat exchange efficiency.
