Specific embodiment
The utility model is further described below by drawings and examples.By these explanations, this practicality is new
The characteristics of type and advantage will become more apparent from clearly.
Dedicated word " exemplary " means " being used as example, embodiment or illustrative " herein.Here as " exemplary "
Illustrated any embodiment should not necessarily be construed as preferred or advantageous over other embodiments.Although each of embodiment is shown in the drawings
In terms of kind, but unless otherwise indicated, it is not necessary to attached drawing drawn to scale.
According to boiler provided by the utility model flue gas disturbed flow pipe, as shown in Figures 1 and 2, boiler flue gas flow-disturbing
Pipe,
The disturbed flow pipe includes flow-disturbing tube body 1 and the flue gas turbolator 2 being arranged on inside flow-disturbing tube body 1,
The flow-disturbing tube body 1 is light pipe, and light pipe refers to smooth pipe in the application；
The flue gas turbolator 2 in the shape of a spiral, is reversed by thin plate and is formed, as shown in Figure 2；
