Drawings

Hello there, I was wondering if anyone knows where I could find some technical data for circulation fluidized bed gasifier. It generally doesn't matter what size it is, or if anyone has some data for other gasifier, that would be fine. All it is required from me is to model gasifier for some presentation, but I have a bit issue in finding some model or drawings so I could get some dimensions and get overall idea in size of that system.
If anyone could provide me some useful links, I would be very thankful. I searched for a couple of days and it appears as I cannot find anything useful.
Some link to help you understand what I mean is https://www.sciencedirect.com/science/article/pii/S1364032114006595

Best regards,
Davor
