This paper describes a new optimized design scheme for the connecting pipes of condenser rear water chambers. In this proposal

the columns of turbine house passes through the connecting pipes of condenser rear water chambers via low resistance alary casings so that the double pressure condenser rear water chambers can be directly connected by the pipes with short pipeline

less elbows and low resistance. It is not only good for the turbine house arrangement

but also can save 60 tones of steel comsumption and reduce the auxiliary power 61× 104 kWh. Moreover

this paper provides the calculating model and relevant formulas.
