Where ?
I can't find any boiler on any google earth pro image.
It's buried in some Chinese forum. GE imagery is also typically too outdated to keep up with the most recent developments so I wouldn't rely on it.

That being said, it's just hearsay and not verified. Personally I think it makes more sense to use steam propulsion, which is tried and proven for large vessels. I doubt the PLAN will go from a steam-powered 001 and 002 to gas-powered 003, and then back to steam for CVNs.

The Google maps / earth contain maps with 3D features and so on, so they are updated slowly.

However the GE pro (pc installation ) contain new images if you choose the "historic imagery " option.
Surprisingly, the standard GEP / GM / GE image is from 04/10/2018, but with historic imagery the latest is 29/10/2019 , for the Jingnan shipyard.

So, the GEP only 60 days older than the latest , grainy satellite image post on this forum.

There is something called the QD400 that showed up in the AECC catalogs. If you remember QD280 is the gas turbine used on the 052D and 055 and QD70 is for the Type 726 LCAC. QD400 is a 40MW gas turbine, likely for marine use. Four of this could deliver what you need for a carrier, with four 12MW diesel engines like those used on the 075.

My understanding is QD models gas turbine are for Industrial power generation while QC models are for ship propulsion. AECC official website cited all QD gas turbine are for 工业发电, meaning Industrial electrical power generation. QD probably stands for qidian 气电 (abbreviated for 燃气机发电).

QC models have been cited for ship used through out many years, and QC would be for qichuan汽船 (abbrivated for 燃气机船用).

QD/QC series were developed by 606 Institute while the CGT series were developed by 703 Institute.
