Mechanical Property Evaluation and Remaining Life …

1/3/2001 · This paper is aimed at investigating the residual life of more than eleven years service - exposed main steam pipes of various boilers in a thermal power plant. The remaining life assessment for safety were made using destructive accelerated stress rupture and tensile tests at different temperatures, and some nondestructive tests. There was no evidence of localised damage in the form of

1/10/2007 · During this period, the size of PC plant boilers increased by nearly 70% while the average efficiency of the overall PC power plant increased from 29.9% to 37.6%. These improvements in economy of scale and overall plant efficiency (attributed in part to improvements in other plant areas) are reflected in the boiler capital cost per unit of net capacity (in $/kW).

1/11/2013 · A bounding value for this transient steam pressure of 181.6 barg was used (a peak differential pressure of ΔP = 142.6 barg). The differential pressure in cold shutdown is zero. Boilers which have been powered-down and disconnected from a running reactor are either depressurised or nearly so.
