Original abstract
In the present article a process of the retrofit of the desulfurization absorber in the Plzenska energetika power plant in the city of Pilzen, the Czech Republic, is described with details provided on the modeling approach to both the flow field in the desulfurization vessel and the performance of the rotary atomizer used there. The retrofit is performed on the numerical basis using CFD code with a simple yet correct and validated model for the semi-dry desulfurization. For the numerical modeling of the multiphase flow in the absorber the Euler-Lagrange approach is used with the Eddy Interaction Model. The retrofit measures that were numerically tested focus on the optimization of the flow field inside the absorber with the goal to increase the time during which the lime slurry remains in contact with flue gases. The main idea behind the retrofit was to keep the installation costs of the retrofit measures as low as possible yet improving the desulfurization efficiency. Results of the numerical modeling are in very good agreement with operation tests.

Článek se věnuje využití modelování proudění a procesu odsíření při rekonstrukci odsiřovacího absorbéru včetně vlivu parametrů rotačního atomizér. Při rekonstrukci se využilo numerických výpočtu na bázi CFD s implementovaným modelem pro polosuché odsiřování. Pro numerické modelování vícefázového proudění v absorbéru byl použit Euler-Lagrangeuv.
