Flow Field Simulation on ESP Inlet Head Coagulator
摘要
Abstract
The coagulator is usually arranged in the straight fuel of electrostatic precipitator (ESP)inlet,therefore,a longer straight fuel is needed.But it is difficult for reconstruction of the ultra-low emission for the coal-fired power plant.This pa-per presents a scheme of moving the coagulator into the ESP inlet head so as to solve the above problem.On the basis of cal-culating and comparing turbulence intensities of the inlet head and fuel and particle trajectories,it discusses reasonability of this scheme and influence on ESP air flow distribution.Analysis results indicate turbulence of the flow field in the inlet head is weaker than that in the fuel,and it is able to realize effective mixing and collection of particles by reasonable arrangement of partial electric field so as to ensure better air flow distribution of the first electric field of ESP.关键词
