Abstract
Through study on performance of air-cooled condenser and air cooling fans for direct air-cooled units
a calculating model of operating performance for air-cooled island system has been established
the thermodynamic characteristic curve of condenser performance under different atmosphere temperature
different cooling air speed
and different load of unit being obtained.Based on the operating mode of air cooling fans
an operation-optimizing model for air-cooled island of the air-cooled unit has been put forward
and directing against the air-cooled island of 600 MW direct air-cooled unit
calculation for performance and optimization being carried out
and the optimized operation mode and optimal back pressure of air-cooling fans in system of air-cooled island being given.
