The flow field of an axial fan in a direct air-cooled condenser for a large power plant is modeled numerically. In order to improve the efficiency of heat exchange of the air-cooled condenser, methods of increasing the rotational velocity of the fan and laying out the guide blade at the outlet of the fan are adopted. Results show that increasing the rotational velocity of the fan can effectively increase the flux of the fan, and can improve the efficiency of an air-cooled condenser; laying out the guide blade at the fan outlet can ameliorate the flow field in an A-flame. This causes the rotational kinetic energy to change into static pressure at the fan outlet, so the ability of the heat exchange of the air-cooled condenser is improved.
