Boiler Ratings | Spirax Sarco

Both these effects reduce the actual steam output of the boiler, for the same consumption of fuel. The graph in Figure 3.5.1 shows feedwater temperatures plotted against the percentage of the 'from and at' figure for operation at pressures of 0, 5, 10 and 15 bar g.

Failure investigation of a secondary super heater tube in a 140 MW …

2017/4/1 · High gas flow velocities can cause tubes to vibrate at high frequencies and result in fatigue cracking failures . Corrosion by combustion product, oxidation and by impure boiler water can significantly reduce the tube wall thickness and result in failure of a tube many years before the expected end of its useful service life.
