Abstract:
The exterior flow field of air-cooled platform was numerically air-cooled unit. The effects of different wind velocity on heat exchan condenser were analyzed. The cause of air inverse flow at the edge of plat was expounded. The measures to enhance the heat exchange efficiency lated for one 300 MW direct ge efficiency of direct air-cooled form and the hot air re-circulation of the air-cooled condenser were explored so as to make the direct air-cooled unit operate stably and economically.[著者文摘]
