Parsons Marine Steam Turbine Company Parsons Marine Steam Turbine Company Parsons Marine Steam Turbine Company was a British engineering company based in Wallsend, North East England, on the River Tyne. The company was founded by Charles Algernon Parsons in 1897 with £500,000 of capital, and specialised in building the steam turbine engines that he had invented for naval use. The first ship to use a Parsons propulsion system was "Turbinia", launched in 1894; the successful demonstration of this vessel led to the creation of the company and the subsequent construction of the engines for the first two turbine-powered destroyers for the Navy, and , launched
Mercury vapour turbine is used to raise steam for the steam turbine. The Hartford Electric Light Co. (U.S.A.) has a 10,000kW turbo-generator driven by mercury vapour, which reaches the turbine at 70 lb. per sq. in. (gauge), 880°F. The mercury vapour is condensed at 445°F and raises 129,000 lb. steam per hr. at 280 lb. per sq. in. pressure. The latter is superheated to 735°F and passed to the steam turbines. During 4 months continuous operation, this plant averaged about 0.715 lb. of coal per kWh of net output, about 43% of the output being from the mercury turbine generator and 57% from
