ABSTRACT = {Aiming at the problem that the total pressure loss of the flue of the electric precipitator of the 350 MW unit of a power plant to the inlet of the draft fan is
too large, the numerical simulation software Fluent and the standard <i>k-ε</i> model
was used to simulate the flue, the results show that the main part of the flue mean
total pressure loss is derived from the confluence header and elbow. In order
to reduce the loss and consider the cost of transformation, the concept of twodimensional feature surface is established, gradually proposed three sets of flue
transformation program and analysis of the flue transformation program drag
reduction effect, the results show that the total reduction of the flue can be reduced
from 486 Pa to 89 Pa and the reduction rate is 81.7%, which is the best solution;
The concept of two-dimensional feature plane is helpful for quick condensing of
flue; Double V-type structure of the convergence of the box has a better drag
reduction effect.},
