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.

The shafting stability was introduced aiming at 1000MW ultra-supercritical turbine-generator set of Zouxian power plant phase IV. The results calculated in design, which included instability speed, specific pressure, and logarithm damping ratio of bearing, the lateral vibration and torsional vibration properties of shafting, were analyzed. The shafting stability was judged by adopting Q factor method. The causes of steam flow excited vibration and its design criterions as well as preventing measures were expounded. The operating status after putting the measures in practice was described briefly, and the basic stability criterions of turbine shafting used by main manufacturers abroad were recommended.
