I don't work in the industry, but as far as I know the limitations are economic not engineering. Vestas new V90-3.0MW comes on a choice of towers; 65, 80, 90,or 105m.
I am looking for a ballpark number for the furnace, so your number looks good, Paul. Thanks.
If there are specific technologies (CFB or supercritical?) that provide a greater transfer rate I would be interested in that information as well.
