    The question is will 12,100 pounds of molten salt at a temperature of 1050 stored in a 3 by 8 storage tank run through a heat exchanger generate enough steam to run this generator for 4 hours?

    If not then how much will be needed?

    This article has information on how large the salt tank needs to be.

    http://en.wikipedia.org/wiki/Thermal...alt_technology

    A 100-megawatt turbine would need tanks of about 30 feet (9.1 m) tall and 80 feet (24 m) in diameter to drive it for four hours by this design.
    Your turbine is 7.5 megawatts, so you would need 7.5% of that. A tank 30 feet high by 80 feet in diameter is 150,720 cubic feet. 7.5% of that is 11,304 cubic feet.
    If your tank is 3 feet high by 8 feet diameter that is around 150 cubic feet. So that's about 1/75 of the size you need.

    Thnaks Harold. I wasn't sure if there was a direct correlation but that is actually the spec I used. So wouldntt that be 30' divide by 10 or 10% be 3'?

    So it is better to use volume then tank size?

    Cylinder shape.

    A cylindrical shape that has a diameter of 80 feet and a depth of 30 feet has a volume of:

    Volume
    = 4270.1 cubic meters
    = 4270100000 cubic centimeters
    = 5585.1 cubic yards
    = 150800 cubic feet
    = 260580000 cubic inches
    = 1128000 U.S. gallons
    = 4270100 liters


    150800/10 = 15,080 for 10 mw 12,100 for 7.5 mw looks good. But thank you for giving me a baseline to use.
