accommodate the condenser's fouled or blocked tubing is an indication that the plant needs to clean the tubing in order to return to the turbine's nameplate capacity. A variety of methods for cleaning are available, including online and offline options, depending on the plant's site-specific conditions.

In the U.S., ASME publishes several performance test codes on condensers and heat exchangers. These include ASME PTC 12.2-2010, Steam Surface Condensers, and PTC 30.1-2007, Air cooled Steam Condensers.
