    Wind turbine towers

    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.

    Heat transfer in a coal boiler?

    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.

    Could any tell me what the heat transfer rate (W/cm2) is in a typical modern coal boiler? Thanks
