Creep Classification of Grade 91 Steel
Background Grade 91 steel is superior to many other industry used materials for its increased resistance to m...
Today’s combined cycle power plants can achieve near 60% efficiency when new and operating at the design load-case, but operating off-design can severely reduce efficiency and hence the heat-rate. The challenge is two fold:
Typically, performance losses are associated with age-related degradation (for example fouling),off-design operation, or modifications that lead to changes in process conditions (for example, a GT upgrade that affects downstream HRSG performance).
Tetra Engineering has the experience and tools for identifying the origin of performance losses and how they might be recovered in considering the feasibility and cost-effectiveness.
