Condition assessment is carried out to arrive the present state of the condition of components property degradation using non - destructive and destructive methods. Condition assessment plays a vital role in running plant without any interruption and meets increasingly stringent environmental regulations, planned outages, proper maintenance and data collection in new as well as old plants. It is an ongoing procedure rather than one time activity. This paper enunciates salient features of condition assessment of boiler from the experience gained over the period of years in this arena to arrive the scope including metallographic spots, selection of non - destructive and destructive tests, planning, execution (bar charts) and reporting.
