In this paper, gas reheat with recuperation was applied to the regular triple-pressure steam-reheat combined cycle (the Regular cycle) by replacing the GT unit with a recuperated gas-reheat GT unit (requires two gas turbines, gas recuperator, and two combustion chambers).
According to cellular pattern evolution and velocity measurement, a recuperated detonation with nearly the same velocity as the undisturbed incoming wave finally develops downstream in both channels, at a distance of about four times the channel height (160 mm).
The temperature rise of recuperated air in the recuperator has great impact on the performance of this recuperated unit.
Catalase levels (P<0.05) remained significantly elevated in the recuperated group compared with controls at 12 mo of age.
At 22 d of age, MnSOD and catalase protein levels were significantly (P<0.001) increased in the recuperated group compared with controls (Fig. 5 A ).
At 12 mo of age, both aortic and WBC levels of CoQ9 were significantly reduced (P<0.05) in the recuperated group compared with control animals (Fig. 2 A).
At 22 d of age, aortic CoQ9 concentration was significantly reduced (P<0.05) in the recuperated group compared with controls (Fig. 2 A ).
At 22 d of age, NEIL-1 protein levels were significantly (P<0.05) increased in the recuperated group compared with controls (264±54 vs. 100±25%).
Taken together with the increased NOX-4 protein expression, reduced linked complex II-III activity, and CoQ9 deficit, this suggests a specific mitochondrial dysfunction in the aortas of recuperated offspring associated with an increase in oxidative stress.
Consistent with the CoQ9 deficit, a significant (P<0.05) reduction in linked complex II-III activity was observed in the recuperated group compared with controls at 22 d of age (Fig. 2 C), whereas there was no difference in complex I (0.2±0.03 vs. 0.2±0.04 ratio to CS activity) or complex IV activity (0.01±0.001 vs. 0.01±0.001 ratio to CS activity).
