NUMERICAL RESEARCH ON A DIRECT AIR-COOLED CONDENSER WITH A FLOCCULE-PROOF SCREEN INA POWER PLANT

This paper solves the floccule-proofing problem encountered in the actual operation of an air-cooled condenser by relying on the technological alteration project of a 2×660MW power plant. Numerical simulation, analysis and research are conducted on the thermos-flow performance of the direct air-cooled condenser (DACC) in different wind directions under performance assessment conditions. The material, structural style, porosity, resistance co-efficient and installation position of the floccule-proof screen are determined. Floccule-proofing is realized by utilizing an engineering design margin while the air-cooled condenser is made to meet the requirements of performance assessment conditions. The research provides a theoretical basis for the operation and optimal design of a DACC.
