PRESSURE COMPOUNDING
Compounding of steam turbine is used to reduce the rotor speed. It is the process by which rotor speed come to its desired value. A multiple system of rotors are connected in series keyed to a common shaft and the steam pressure or velocity is absorbed in stages as it flows over the blades.
Research approach. In this way, compressors increase pressure and compress gases using their blades. In contrast, turbines reduce the pressure of flow media such as steam or gases in order to convert the expansion of these media into power that makes the blades rotate.

PRESSURE VELOCITY COMPOUNDING
It is a combination of the above two types of compounding. The total pressure drop of the steam is divided into a number of stages. Each stage consists of rings of fixed and moving blades. Each set of rings of moving blades is separated by a single ring of fixed blades.
