What are the effects of air leakage in the condenser?
by

1 Answer

Answer :

1. It increases the back pressure on the turbine with the effect that there is less heat drop and low thermal efficiency of the plant  
2. The pressure of air in the condenser lowers the partial pressure of steam, which means steam, will condense at a lower temperature and that will require greater amount of cooling water.  
3. It reduces the rate of condensation of steam, because air having poor thermal conductivity impairs the overall heat transfer from the steam-air mixture.
