Steam Turbine Parts
Diaphragms are a key component to the overall performance of your steam turbine, and the degradation of the diaphragms can have a big impact.
As little as a 5% deviation of total nozzle area can equate to a significant loss in both Heat Rate and Output of your turbine. If diaphragms are not repaired during the outage, these losses will be not only maintained, but increased throughout the next outage period.
