Reliability engineering appraisal for power plants life assessment and management
- Monash Univ., Churchill, Victoria (Australia). Gippsland School of Engineering
Reliability engineering in power plants life assessment and management aims at minimization of life synthesis cycle plant cost without compromising plant safety. Power plant reliability depends, as discussed in the present paper, on power plants life synthesis and various reliability methods such as synthesis based analysis, design, and manufacturing, operating conditions, plant reporting and recording system, plant failure analysis system, and field operational data on the same or similar power plants components. The paper presents a new approach to power plants reliability engineering appraisal. The approach, designed specifically to form part of a power plant`s overall life assessment and management, introduces a flexible mechanism for appraisal. This is done through the introduction of the Reliability Appraisal Matrix (RAM) of various reliability methods. In addition, RAM is introduced for Boiler Tubing (BT) life synthesis in relation to new, random and remnant life of BT. RAM is also introduced for BT components, namely stress rupture, water-side corrosion, fire-side corrosion, erosion, and deficiency of quality assurance leading to failure. In fact, there is a growing need in the literature to find an indicator of reliability appraisal. The indicator is introduced in the present paper as RAM. The paper recommends the standardization of RAM as an adaptable and dynamic mechanism for engineering reliability appraisal of power plant life assessment and management. Furthermore, the recommended standardization of RAM coefficients should account for different classes of power plant components, operating conditions, maintenance procedure and age.
