1948 Engineering: Some of the significant engineering

This 80,000-kw turbogenerator, put on the line late in 1948, is the third of five such units for the Port Washington plant of the Wisconsin Electric Power Company. The turbine is a tandem-compound design, using the reheat cycle. New concentrically-mounted hydrogen coolers have reduced the diameter of the generator housing and halved the total ventilating hydrogen volume. Steam conditions at throttle are 1,290 pounds per square inch (gauge) and 850 degrees Fahrenheit, with reheat at 850 degrees Fahrenheit and exhaust at 29.5 inches of mercury.
