| Abstract: | Thermal performance of the N-11220-1 power plant condenser is numerically studied using the computer program developed by author. It's pointed out that the performance of the condenser can be improved by means of either replacing the original tube bundle with a fully new more advanced one or increasing the sizes of steam lanes around the tube bundle after a series of detailed numerical experiments. |
