Abstract
In this paper the author first gives an account of the early experiments made, after which the thermodynamic possibilities of the process are taken up. The 1800-kw. installation in the plant of the Hartford (Conn.) Electric Light Co. is then described, following which boiler problems, leakage, packing, and related topics are discussed, as well as the question of mercury supply. An appendix to the paper includes a table of the properties of mercury vapor at absolute pressures ranging from 0.4 to 180 lb. per sq. in. abs., a Mollier chart for mercury, and a chart showing the available energy of mercury vapor in watt-hours per lb. for expansions from absolute pressures of from 20 to 85 lb. per sq. in. to back pressures of from 0.4 to 1.6 lb. abs.
