  • Boiler Pressure Parts Remaining Life Expectancy - Bright

    Aug 18, 2009 · Remaining life prediction techniques. There are many methods used by engineers to predict the remaining life of boiler pressure parts. The most commonly used technique is the steam side oxide scale thickness growth and life fraction rule using Larson-Miller parameter. Every tube in service has a Larson-Miller parameter that increases with time.
