8  Plant Testing

8.1  Introduction

 

Condenser thermal performance tests are carried out for two reasons:

  • As acceptance tests to establish that a condenser meets its specified performance, and is capable of producing the desired condenser steam inlet pressure when operating under specified conditions.
  • As routine operational tests to monitor the condenser performance periodically, and to verify that station thermal efficiency is not being adversely affected by a deterioration in the condensing plant heat transfer coefficient.

In both acceptance tests and routine tests, a high standard of instrumentation is required, particularly in the measurement of the condenser steam inlet pressure, and the cooling water temperatures. Routine tests generally use less instrumentation than acceptance tests, but only when it is certain that this is not detrimental to accuracy.
