Those are certainly going to be the uptakes for the rear generators. We can also now see the uptakes for the forward generators.
I don't think uptakes (intakes?) would cause the air to shimmer like that as seen in photo #3 in post #5901. That said, I think in the same structure we can also see the uptakes for the rear generators as well -- assuming I'm interpreting your words correctly.
Red circle below: rear funnels
Red square below: hot exhaust from funnels
Green circles below: air uptakes/intakes
Uptakes = exhaust
Downtakes = intakes
The bottom green circle is not an air intake for the generators, but like the others that are more visible, they are just ventilation for the uptakes. The upper green circle I am not yet able to identify, but seems like it would be too small to be a downtake, especially one for a GT generator.
I can't help to think about JY-26, working on UHF/VHF. I think the size of the array would be pretty close to the ones on 055.
The ones on the Type 055 has to work on S-band (consumer knows this as your Wifi band) so it can track aerial targets much more precisely needed for accurate targeting for the HQ-9 missiles. It can't work with UHF/VHF on that subject.
Something like the JY-26 can be a replacement to the Type 517 radar on the Type 052D however. These are the aerials that are on the back of the ship.
S-band radars cannot perform "accurate" targeting for HHQ-9 missiles. They can provide early and mid-course guidance for the missiles but C-band or X-band will be needed for the actual targeting, same reason the S-band SPY-1 is not used for targeting, rather its slaved SPG-62 in X-band.
As for UHF/VHF, it would make perfect sense for such a radar to work with the other radars in the kill chain of the HHQ-9 by being the initial detector, especially for stealth targets, in ascertaining a very general location of the target for the S-band radar to focus a narrow search on with perhaps most or even all of its T/R modules, and after detecting the target and providing early/mid-course guidance for the outbound missile, hand off final terminal maneuvers to the X-band radar.
That is a heck of a pic:
Particularly when you realize how many of these ships the CHinese are building and how quickly.
By the time the second carrier is IOC, they will have enough of each to form battle groups around both...and with several more to spare.
Of course with the next carriers to come, they will need them all.
Very modern, very capable carrier groups.

I think your idea and my idea for targeting is a bit different. In my case, the target has been determined by its range, heading, and bearing to be a threat, and the radar hops to a higher band frequency and PRF for an even more accurate and rapid updating of tracking of range, heading and bearing of prioritized targets, accurate enough to slew the SPG-62s towards the prioritized target and keep slewing, and provide mid phase updates to the missiles on air. Homing and illumination is done by the SPG-62.
I'm on board that HQ-9B and its successors might likely be ARH seekers, and doesn't need a shipboard C or X-band for target illumination. The higher frequency edge of the S-band combined with high PRF would be accurate enough to bring the missile into the catch basket of the active seeker. C-band is needed for target illumination for homing, the SARH or TVM HQ-9 doesn't support X-bands anyway. Land based HQ-9 mobile station is all C-band, which means aside from the initial detection by a separate long wave radar, this means track while scan, target priority for engagement, and target illumination (CWI) are all done by the same panel on C-band. In the case if the missile is an active seeker, the last stage is omitted. There is likely a separate search and detect mode in case if the separate search radar is not present, disabled or destroyed.
