The function of a governor is to control the fluctuation of speed of a prime mover within the prescribed limits with the variation of loads on it. In case of steam turbines when it is connected to drive an alternator for converting its mechanical energy into electrical energy, device is used to vary the turbine output according to the load [...]
In this article we will discuss about:- 1. Simple Impulse Turbine 2. Reaction Turbine 3. Impulse Reaction Turbine. Simple Impulse Turbine: The impulse turbine depends completely upon the dynamic action of the steam. The direction of motion of the steam is changed as it passes across the blade. As a result of change of direction of steam across the blade, [...]
Compilation of lecture notes on ‘Steam Turbines’ for engineering students. Lecture Note # 1. Optimum Operating Conditions: Lecture Note # 2. Blade Height of Turbine: For impulse turbine the blade height at a particular section of a turbine will be function of mass flow rate (m), specific volume (v), area (A), and velocity of steam Let, P = pitch = distance [...]
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 [...]
