High-pressure steam power plants, 1920s
Boston Edison's Edgar Station becomes a model for high-pressure steam power plants worldwide by producing electricity at the rate of 1 kilowatt-hour per pound of coal at a time when generators commonly use 5 to 10 pounds of coal to produce 1 kilowatt-hour. The key was operating a boiler and turbine unit at 1,200 pounds of steam pressure, a unique design developed under the supervision of Irving Moultrop.
