7. Protecting the superheater tubes from high temperatures during startup is accomplished by gas recirculation, or gas tempering?

8. Does gas recirculation in the lower furnace cause an increase or decrease in the heat transfer rate?

9. Spray attemperators inject a fine mist of high purity water to control steam temperature.

10. Gas recirculation is used to control final reheat steam temperatures. There is a spray attemperator in the "hot reheat line", but under normal operating conditions, its use should not be necessary. {I have noted that 33% = 1,400,000 at 2500 psig; Full Load = 4, 200,000 at 3000 psig, econ included. The psig = "pressure per square inch gauge".}
