Abstract

Assessment of service availability and integrity of power plant component materials requires the use of methodological approach, that includes service history data acquisition and analysis; defining a programme for material state non-destructive and destructive testing; and formulating acceptance criteria. Data based on boiler service history and on previous test results, comparing the new results to adopted acceptance criteria served as a basis for integrity assessment of hot-water boiler at plant “Mirijevo”, belonging to JKP “Beogradske elektrane”. Following the integrity assessment of critical boiler piping system parts, a proposal is defined for partial replacement of boiler wall tubes and a sequence of service recommendations how to prevent appearance of wall tubing damage is also given.

Keywords: hot-water boiler, non-destructive tests, destructive tests, integrity assessment, corrective and preventive measures
