  • Mercury as a Working Fluid. - Douglas Self

    2019-8-19 · MERCURY Mercury has got to be the ultimate dodgy working fluid mercury: as remarked elsewhere on this site, in the Steamwheel gallery, (where mercury is used as a weight and sealant rather than a working fluid) it is an insidious poison of a most unpleasant kind. It has a much higher boiling point than water, at 357 degC.

    2019-10-3 · On maintained full-load the heat output averages 9800 BTU per net kWh [34.8% efficiency]. It is believed that maintenance costs will be lower than in ordinary steam plant. The back-pressure on the mercury turbine is fixed by the steam boiler pressure; only a small vacuum pump is needed, as there is no air or other gas in the mercury system.
