Curtis Steam Engine
Curtis Steam Turbine, about 1895Smithsonian American History Items
This experimental turbine is of the type patented in 1895 by Charles G. Curtis of New york. The Curtis turbine is divided into several sections, to divide the pressure drop into stages and thus reduce the speed. Each stage uses a group of divergent nozzles, similar to those used by C. G. P. De Laval, to direct the steam against the wheel vanes. The turbine takes advantage of both the expansion (recaction) and the velocity (impulse) of high-pressure steam.
The first large turbine installation in the US wsa at the Fisk Street Station of the Commonwealth Eduson Co, where General Electric erected the first unit in 1903. These units were also the first with capacity as great as the largest reciprocating engine of the period. The vertical design was used to save floor space.
