Steam power plant basically operates on the Rankine cycle. Coal is burnt in a boiler, which converts water into steam. The steam is expanded in a turbine, which produces mechanical power driving the alternator coupled to the turbine. The steam after expansion in prime mover (turbine) is usually condensed in a condenser to be fed into the boiler again. In [...]

There are many ways of classifying water or hydraulic turbines, for example, according to the type of flow of water, according to action of water on moving blades, according to head and quantity of water available, after the name of originator and according to the specific speed of the machine. According to the type of flow of water, the water [...]
In this article we will discuss about:- 1. Operation of Steam Turbines 2. Classification of Steam Turbines 3. Compounding. Operation of Steam Turbines: The operation of a steam turbine is based upon the principle that the steam issuing from a small opening attains a high velocity. This velocity attained during the expansion of the steam depends on the initial and [...]
