Are those adjustable exhaust hoods? Is there some blower that pulls the smoke/etc. out of the room through those adjustable hoods?

Anybody know?

The hoods you see over the forges are not for exhaust, they are for intensifying and concentrating the amount of heat that can be produced

They are a downdraft hood. Some of the exhaust can be recirculated through the blower to increase heat, but they do extract through the floor via a ducted system.

It looks like you are correct when I blow up the picture I could see what looked like a rectangular duct going down the back of the forges
