To design the flue duct and condensate water collector for the chimney more scientifically

on the basis of the CFD method

a model coupling Eulerian wall Film model and mixture model was applied to simulate the distribution characteristics of water film

which is from the saturated wet flue gas at outlet of the wet electrostatic precipitator

that condensing on walls of the flue duct and double-inner cylinder sleeve titanium plate stack.The calculation shows that

under the extreme weather conditions with the boiler of the maximum continuous evaporation amount

the maximum condensation amount above the expansion joint was 12.99t/h

and that below the expansion joint was 1.75t/h.Moreover

analysis shows the water film regions where liquid film would most likely be re-entrained were the inner wall at the chimney entrance

the inner wall of the expansion joint and the top of the ducts near the stack.
