Abstract: Four schemes of steam discharge into air cooling system were planned according to the different nameplate output definition for 1000MW unit. The process flow of direct air cooling system was described. The heat-transfer area of air cooling condenser (ACC), the number of fans and duct rows, the diameter of discharge ducts and the height of the ACC platform for each scheme were determined by detailed calculation and analysis. The result can be used as reference for the construction of air cooling system in 1000MW unit.
