Online Training - Boiler Life Assessment

DESCRIPTION Boiler life assessment is the process of evaluating the remaining useful life of a boiler, predicting its future performance and identifying potential issues or risks that may affect its longevity. It involves a comprehensive analysis of various factors such as boiler design, operating conditions, maintenance history, and inspection data. OBJECTIVE

• Evaluate the present state and the condition of the boiler components in order to continue stable and reliable boiler operation.
• Evaluate the remaining life for superheater and reheater by metallurgical inspection.
• Evaluation of creep life and future inspection scheme by metallurgical inspection for water wall, economizer, superheater and reheater tubes.
• Evaluation degree of creep damage for superheater and reheater by hardness test.
• Evaluate the remaining life based on thickness measurement for water wall.
• Evaluate the remaining life based on thickness thinning for economizer due to low temperature corrosion.
• Evaluate the remaining life based on thickness thinning for superheater and reheater tubes due to high temperature corrosion.
• Confirm the cause of the inner scale generation.
• Evaluate the remaining life based on check of metal structure, inner scale, etc for sample tube.
