This article focuses on the optimization design of tower type for natural draft wet exhaust smoke cooling tower using optimization calculation methods based on a detailed research of typical 1000MW coal fired power units and existing design code. According to the main changes parameters of cooling tower including tower height and bottom diameter ratio、throat diameter and bottom diameter ratio、inlet height and bottom diameter ratio and fill height, the optimization calculation program of water supply system was used to decide the selection and economical allocation of cooling tower.The result shows that the dimension of the natural draft wet cooling tower is relatively more appropriate and practical when the cooling towers are selected using optimization calculation of water supply system and in combination with optimization design of cooling tower body.
