Historical review

·Steam-dryers and steam-traps can remove condensed water from the pipes,and steam-jacketing can reduce cylinder condensation they do not eliminate the problem.

·It was realised in the 19th century that once the steam was removed from proximity with water in the boiler it could receive additional heat and its temperature could be raise above the boiling point.

·This is referred to as "superheating".

·With sufficient additional heat,the rise in the temperature of the steam would more than compensate for the fall in temperature as it passed through the pipe-work and engine and condensation could be eliminated.

·Tube failure is one of the leading causes of forced outages in power plants. One of the key ways of preventing failure is to predict the remaining useful life of tubes.

·By gaining an accurate assessment of the predicted lifespan of the tube, power plant operators have the necessary information to make decisions on prioritising future inspections, and whether to run, repair or replace tubes.

·How we analyse the remaining useful life of tubes:

·The lifespan of a superheater or reheater tube is affected by time, temperature and stress.

·To measure the remaining useful life of the tube, information on the steam pressure, original and present wall thicknesses and the tube’s outside diameter (OD) is used to calculate the stress history of the tube. ·The steamside scale thickness is used to gauge the effective temperature history of the tube.

·The stress history and the effective temperature history are compared to the creep rupture material of the specified tube material. From this information, the remaining useful life of the tube can be calculated – as well as the temperature profiles across the boiler.

·Hot spots and wastage patterns can also be identified.
