The 2000-Psi, 1050 F, and 1000 F Reheat Cycle at the Philip Sporn and Twin Branch Steam-Electric Stations

The economical generation of steam-electric energy is affected by such factors as site, fuel, cycle, and equipment. A discussion of these basic factors serves as introduction to a description of the program involving the addition of 525,000 kw of generating capacity to the Central System of the American Gas and Electric Company at the Tidd, Philip Sporn, and Twin Branch Steam-Electric Stations. The discussion of the design employing 2000-psi 1050 F initial temperature with 1000 F reheat at the Philip Sporn Plant includes the location of the plant on the system, features of the site, the heat cycle, turbine, boiler, and plant layout. A net plant heat rate of 9270 Btu per net kwhr output is expected.
