industrial boiler engineers will switch to a [more expensive] high grade steel for all superheaters but above 480 °C they will switch again and at 510 °C or thereabouts they will switch to exotic metals for at least the hottest part of the superheater. Few will even consider an HP steam temperature above 525 °C. Cost and Benefit Analysis
1 Symmetric double-flow high-pressure turbine with low wall thickness 2 Full three-dimensional, high-performance, and variable-reaction blading
4 5 1. High efficiency (even at part loads) - low operating cost. 2. Wide fuel band - can burn coal, lignite, washery rejects, pet coke etc.
