Consider Problem 17.10. Show the effect of the metal mass on the temperature transients during shutdown. To show this, ramp down the fuel flowrate to 20% of its steady-state value in 4 h and then completely close the fuel control valve, CV-1106. The air continues to flow with the flowrate being the same as when the fuel flowrate was 20%. Show the temperature transients of Streams 6 and 7. Now increase the metal mass of E-1104 and E-1105 by 50%. Carry out the same test again. Compare the temperature transients with what you obtained before.
