Research of Deposit Characteristics on Sludge Collector for Steam Generator

Numerical simulation was used to study the flow field characteristics of sludge collector and the effects of key factors on the collection performance.Studies have shown that the effects of different cutting modes on the flow field characteristics of sludge collector could be ignored.With the particle concentration increased,the amount of single mass collection increased,but the single collection efficiency unchanged.Under the condition of the same inlet and outlet of sludge collector,with the particle diameter increased,the collection capability of sludge collector increased.There was an optimum inlet and outlet aperture of sludge collector in each particle diameter.
