Steam Turbine Construction
Introduction:
There are two
main types of steam turbine, impulse and reaction. The principles are different,
but the processes construction are somewhat similar. In either type steam is
caused to impinge on blades carried on a rotating part. The high speeds and
stresses involved necessitate great strength and accuracy of manufacture. Since Sir Charles A. Parsons produced in 1884
his first practicable steam turbine, enormous advances have been made with this
form of prime mover. The generation of electricity on a rapidly growing scale
all over the world during recent years has led to the almost universal use of
steam turbines for the driving of electric generators where water power is
unobtainable. The objective of this module is to present the major features of
steam turbine construction, and support systems.
