VARIOUS TESTS THAT ARE CARRIEDOUT FOR THE CARLA ARE.

The boiler and it’s components are built with assumed nominal design and reasonable l i fe o f operat ion o f about two to th ree decades (one or two hundred thousand hours). These units are generally replaced or t h e i r l i f e i s e x t e n d e d a t t h e e n d o f t h i s period.

This service covers maintenance inspection, repair, alteration & operating procedures for boilers used across all industries.

Under normal operating conditions, and after an initial period of teething troubles, the reliability of these units remains fairly cons tant up to about two decades of normal operation. The failure rate is then increased as a result of their timedependent mater ia l damage. Further r u n n i n g o f t h e s e u n i t s m a y b e c o m e un-economical and dangerous in some cases.

A life extension program comes in handy here. One of the most important steps involved in life extension strategies is the assessment of the remaining life of the existing components so that required timely refurbishment steps can be introduced to extend the plant l ife. Remaining Life Assessment (RLA) becomes a necessary evil.

REPORTING

RECOMMENDATIONS

The final report is generated with all the test results analyzed and evidence of damage recorded. Recommendations are made to attain longer, more reliable and safer operations of the boiler.

Based on the findings and analysis of the test results a 3R decision is made to either Run the boiler, Repair the boiler or Rerate the boiler for safe operation and enhancement of boiler efficiency.

By initiating timely preventive measures a n d b y w a y o f p r o p e r m a i n t e n a n c e refurbishment actions, it is possible to retain these units in service safely, reliably and economically for many more years.
