FIGURE 20 Tube bundles in HRSGs require appropriate support
mechanisms; thermal cycling in combined-cycle units makes this

consideration even more important. (Power.)

GAS-TURBINE-PLANT OXYGEN AND FUEL INPUT
DETERMINATION

In a gas-turbine HRSG (heat-recovery steam generator) it is desired to raise
the temperature of 150,000 lb/h (68,100 kg/h) of exhaust gases from 950°F
(510°C) to 1575°F (857.2°C) in order to nearly double the output of the

HRSG. If the exhaust gases contain 15 percent oxygen by volume, determine
