When designing mixing device, it is considered as matching, the balance of pipeline crushing.When calculating flow resistance loss, for flue
There is certain rubbing action in road since air itself has between viscosity and air and tube wall, it is contemplated that gas density very little, on
Riser section hydrostatic resistance loses and acceleration drag losses are all negligible, and such pipeline section drag losses include mainly in air-flow
When friction loss and air-flow caused by friction flow through spiral blending blade, demister, the size and Orientation of flow velocity occurs
Thus variation generates the local resistance loss caused by local eddy currents.Spiral blending blade, demister crushing are more relatively large, but
Blending, foam removal channel cross-sectional area are much larger than inlet channel sectional area, and blending flow velocity is slower, and crushing is small, can also be supplied by improving
Atmospheric pressure and flow compensate crushing.
